DESIGNING THE FUTURE OF INFORMATION The Internet Beyond the Web

Current computer science operates with models of information, networking, and databasing that were conceived in the mainframe era and cannot serve the needs of a truly connected world. Two unique initiatives—the “Information Commons” of MAYA Design and “Internet Zero” from MIT’s Center for Bits and Atoms—offer simple, proven foundations for the intense complexity of a global information economy.

Designing the Future of Information The Internet Beyond the Web

Designing the Future of Information Overview “The Information Commons” (Maya Design, INC.) 4 Global information space for everyone. Overcomes the Web’s “information islands” to offer scalable interoperability for the pervasive era. Enables civic computing with public data but protects intellectual property for commercial use.

4 New information technology, next-generation capabilities. Simple, scalable architectures for information devices, data storage, and information itself. Enables sophisticated fusion and visualization of data that will never be possible with the Web alone. The result of $50M in R&D to date.

4 Global P2P system. Fully distributed computation and storage/retrieval. 4 Proven in commercial, government, and non-profit implementations. “Command Post of the Future” helps run U.S. military operations in Iraq today.

4 Free access and browsing/authoring app. Java-based “Civium Workbench” in public beta by the end of 2005. Powerful geospatial features, among many others.

4 Works with the Web and legacy systems. Information can be published into and out of the Commons from the Web and other systems that use the relational databasing and client-server model that the Commons replaces.

4 Could replace the Web. Future-proofed design principles and “emergent intelligence” potential could make it the Web’s replacement for the 21st century.

4 Multi-disciplinary team and approach. Research lab/design consultancy spun out of Carnegie Mellon University. Includes luminaries from the fields of engineering, information visualization, interface design, and human sciences.

“Internet Zero” (MIT’s Center for Bits and Atoms) 4 Emerging standard for connecting anything. Replaces today’s many so-called connectivity standards with a truly interoperable “Morse Code for the Internet.”

4 Embeds IP in the physical world. Back-to-the-future concept extends the

scalable, agnostic protocols of the Internet to any device, even non-electronic ones. Incorporates Internet Protocol into physical infrastructure.

4 Multi-disciplinary team and approach. Faculty from many MIT departments. Includes one of the fathers of the Internet itself.

Designing the Future of Information The Internet Beyond the Web

hen it comes to preparing for the global information economy of the 21st century, most people assume that “the technologists are taking care of it.” They take it on faith that the best possible designs for the future of information will emerge from large corporations and centralized authorities. But those are big, unfounded assumptions. In fact, most entrenched entities are showing little appetite for radical departures from current practice. Yet current practice will not serve the needs of a genuinely connected world. This paper examines two real-world initiatives based upon new thinking about information management and networking. They demonstrate that it is possible to migrate gracefully to scalable architectures designed for the era of pervasive computing.

Introduction The Pervasive Internet: IT means what it says For quite a few years now, Harbor Research has focused most of its research and consulting on what we call “the Pervasive Internet”—the convergence of pervasive or embedded computing with the packet-switching “network of networks” called the Internet. We prefer “the Pervasive Internet” over other terms in common use—notably “M2M,” which usually stands for “machine-to-machine”—because it captures the profound enormity of the phenomenon: the world on the Internet, the Internet in the world. Pervasive computing—also commonly called “ubiquitous” or “invisible” computing—usually refers to digital microprocessors and sensors embedded in everyday objects. But even this makes too many assumptions about what the pervasive phenomenon will be. Encoded information in physical objects is also pervasive computing—even without intrinsic computing ability, or, for that matter, without being electronic at all. Seen in this way, a printed bar code, a CD or DVD disc, a house key, or even the pages of a book can have the status of an “information device” on a network.   Lucas, “The Trillion-Node Network,” p. 3. © 2005 Harbor Research, Inc.

But very few people are thinking about pervasive computing on that level. We all casually repeat phrases like “the network is the computer” without really considering the implications. “Pervasive computing” should automatically be understood as “networked pervasive information and computation,” but it isn’t. The nature and behavior of a truly distributed global information system are concerns that have yet to take center stage—not only in business communities, but in most technology communities, too. The “Information Commons” and “Internet zero” In the following pages, we examine two unique and important initiatives from people who are thinking on the scale that the Pervasive Internet deserves—the “Information Commons” of Pittsburgh-based MAYA Design, Inc. (http://www.maya.com/), and “Internet 0” (I0) from MIT’s Center for Bits and Atoms (CBA) (http://cba.mit.edu/). In our years of work on the pervasive phenomenon and its real-world effects on business, we have not encountered more compelling visions of the future of information than these. The creators of both these initiatives have taken great pains to keep their thinking as simple, generalized, extensible, and irreducible as possible. That, as much as anything else, is the theme of this paper. The Information Commons and Internet 0 are disruptive technologies. They are not incremental improvements, patches, Band-Aids, or new flavors of what we already do. They represent a true paradigm-shift in IT thinking. The Information Commons, for example, looks toward the creation of a universal database to which anyone can contribute, and which liberates information by abandoning relational databasing and the client-server computing model. Internet 0 envisions one simple standard, based upon Internet Protocol itself, for networking any information device (even non-electronic ones), rather than the multiplicity of so-called standards we have today. At the same time, taking these initiatives seriously does not mean junking all current IT practice in one fell swoop. The pillars of present-day information technology will not crumble overnight, nor has the great existing investment in them suddenly lost all value. There are reasonable, fiscally sane paths for migrating to the future. But migrate we must. The assumptions and practices of the mainframe and PC eras are now decades old and not suitable for the pervasive computing era.

The “Information Commons” of MAYA Design Can the Pervasive Internet Be “Designed”? “The Pervasive Internet” really means the future of information, and that means the future of civilization. It will require a remarkably agile global network that could comfortably scale to trillions of nodes—some of them hardware, some software, some purely data, many of them coming into and out of existence or changing location constantly. Obviously, such a network cannot be “designed” in any ordinary sense. Certainly, it cannot be designed “topdown.”

And yet the Pervasive Internet must be designed in some sense. Such a network will easily be the biggest technical achievement in the history of humanity. Its closest predecessor is the global financial economy—with which, in fact, it will share vital characteristics. Some basic design principles must be put in place to guide the We are talking here about the design growth of a vast, distributed technological organism that must remain organized as it evolves according to a logic all of systems that will evolve and its own. It demands that we design not only devices and unfold according to a logic all their networks but also information itself in ways not addressed own—a possibility that will require by current IT.

an expansion of our understanding of design work.

“Most Advanced Yet Acceptable” For more than 15 years, this has been the underlying pre“Information Architecture and the Emergent Properties of Cyberspace” —MAYA Design occupation of most work done by MAYA Design, Inc., a multi-disciplinary technology research lab and design consultancy founded by three Carnegie Mellon professors with diverse backgrounds—human sciences, visual design, and engineering. MAYA’s name is an acronym for “Most Advanced Yet Acceptable”—a phrase borrowed from Raymond Loewy, who is usually called the father of industrial design. (Loewy was the creator of the Studebaker Avanti automobile and the Shell Oil logo, among other classic designs.) MAYA’s co-founder and intellectual leader, Peter Lucas, and his longtime collaborator and CTO, Jeff Senn, have tried to connect all their work to the overarching agenda of liberating information from arbitrary restrictions and restraints. Along the way, they have had many illustrious colleagues and collaborators. MAYA cofounder Jim Morris spent eight years at Xerox PARC and worked on the legendary Alto   Lucas, “The Trillion-Node Network,” p. 2-6. © 2005 Harbor Research, Inc.

computer that inspired the entire era of mouse-driven, windows-based computer interfaces. He later left MAYA to become Dean of the Carnegie Mellon School of Computer Science. The late Steve Roth, co-founder of MAYA Design’s sister company MAYA Viz (recently acquired by General Dynamics and renamed simply Viz), was a pioneer in data visualization with his seminal work at Carnegie Mellon’s SAGE group. Many of Roth’s ideas are fundamental to all MAYA software. Bruce Horn, co-designer of the original Finder for the Apple Macintosh, was another early “MAYAn,” as the company likes to call its people. Since their inception, MAYA Design and MAYA Viz have won more than $50M in government and corporate contracts to conduct research and create solutions for next-generation computing and information technology. Their architectural and visualization breakthroughs can be seen in “Executive Command Center,” a commercial product for business, and “Command Post of the Future” (CPoF), a new system for real-time situational awareness and collaborative decision-making now being used by the U.S. military in Iraq. Retired Army General Paul F. Gorman called CPoF the “greatest advance in technology for Command and Control in the past 30 years.” Much of this innovation has now found its way into MAYA’s “Information Commons,” a global information space designed for everyone and every conceivable kind of data, with the scalability and information-freedom needed by the pervasive-computing era. The Information Commons has been in the lab a long time. It’s now coming out into the world—by bringing the world into itself. The Commons already contains, for example, information on all worldwide geopolitical entities, physical features of the Earth, human-created structures such as buildings and transportation infrastructure, U.S. Census data, and much more. By virtue of MAYA’s unique information-architecture concepts, these datasets can be mapped much more powerfully than in most commercial GIS applications. And the Commons allows anyone to become a contributor by creating new units of information or by commenting upon existing ones, all the while clearly separating fact from opinion. Why Do We Need the Information Commons When We Already Have the Web? Before delving into the new thinking that makes all this possible, let’s talk about why it’s necessary at all. Don’t we already have a vast public information space called the World

Wide Web? Didn’t the Web completely revolutionize human communication? And isn’t the Web working and scaling quite handsomely? Almost everyone will answer with a resounding “Yes!” But consider this analogy from Buckminster Fuller: Suppose you are traveling on an ocean liner that suddenly begins to sink. If you rip the lid off the grand piano in the ballroom, throw it overboard, and jump on it, the floating piano lid may well save your life. But if, under normal circumstances, you set about to design the best possible life preserver, are you going to come up with the lid of a grand piano? The World Wide Web is like that piano lid. In a period of great change and tumult, it worked—in the sense that it kept us afloat. But that does not make it the best possible design, or qualify it to be something that we should plan to live on forever. Yet, in the course of one mere decade, the world has become so dependent upon the Web that most people, inside IT and out, cannot bring themselves to think about it with any critical detachment. Even in sophisticated discussions, the Web and its key enabling technologies are usually viewed as utterly inevitable and unquestionable. IT professionals, for example, rarely talk these days about the need for ever-evolving information services that can be made available anywhere, anytime, for any kind of information. Instead, they talk about “Web services.” Even high-tech business people use the terms “the Web” and “the Internet” interchangeably without giving it a thought. But the Web is not the Internet. The Internet itself is a simple, elegant, extensible, scalable, technology-neutral networking system that will do exactly what it was designed to do for the indefinite future. The same cannot be said of the Web, which is essentially an application running on top of the Internet. It is hardly the only possible Internet application, nor is it the most profound one conceivable. Now, after a decade of rampant, unruly Web proliferation, we see that the Internet’s inherent scalability has been both a blessing and a curse. The Internet was able to “give the Web all the rope it wanted,” and today the Web finds itself trying to be something that it was never designed to be: the fundamental platform for the future of humanity’s information. This is the dilemma that MAYA’s Information Commons proposes to resolve by providing something that really was designed to be such a platform—with the extremely well-thoughtout device- and information-architectures required.   “The Internet of Things,” p. 76. © 2005 Harbor Research, Inc.

The Web Consists of information islands The Web’s Achilles heel does not originate in its browsing software, or markup languages, or the other superficial aspects that most users touch directly. Those inventions are not necessarily ideal, but they are useful enough today, and they can be replaced over time with better alternatives. Rather, the Web’s weakness lies with its basic enabling technologies—in particular, relational databasing and the client-server model—and the restrictions they place upon structuring, storing, and reDemand for interoperability is trieving data. The Web stores information in one of two basic ways: utterly unstructured, or far too rigidly structured. The unstructured way gives us typical static Web pages, blog postings, etc., in which the basic unit of information is large, free-form, and lacking any fundamental identity. The overly structured way involves the use of relational database tables that impose rigid, pre-ordained schemas on stored information. These schemas, designed by database administrators in advance, are not at all agile or easily extensible. Making even trivial changes to these schemas is a cumbersome, expensive process that affects all the data inside them. Just as importantly, they make deep, inflexible assumptions about the meaning and context of the data they store. Both of these approaches to data-structure enforce severe limitations on the two things you want most in a global, pervasiveera information system: scalability and interoperability.

growing, and as designers of information devices work to provide it, they will be laying the foundation for an information system far vaster than the existing World Wide Web. Cyberspace will spill from our desktops and extend tendrils into our kitchens, our cars, and our clothing. It will be many orders of magnitude more complex than any artifact human beings have ever encountered. “Information Architecture and the Emergent Properties of Cyberspace” —MAYA Design

The client-server model underlying the Web greatly compounds the problem. Regardless of data-structure, when you put information on the Web you put it in a specific physical location—i.e., you upload your HTML or middleware files, or your database tables, to a specific directory on a specific server. Thus, a Web URL does not point to information per se; it points to the information’s physical location, which is a very different thing. This means that the Web is machine-centric, not information-centric. Information on the Web is not free to move, and because its life is tied to the life of a physical machine, information on the Web can easily become extinct. If a particular server goes offline, temporarily or © 2005 Harbor Research, Inc. All rights reserved. http://harborresearch.com/ [email protected] • 800.595.9368 • 415.615.9400

forever, all its URLs are dead and the information is unavailable. You can “mirror” your data so that copies reside on multiple servers, but this does not change the fact that Web-based information is always tethered to specific locations on specific machines. All of this adds up to a huge collection of information-islands called the World Wide Web. Assuming the islands remain in existence reliably, they are still fundamentally incapable of truly interoperating with other information-islands. We can create bridges between them, but islands they remain. That’s what they were designed to be. The latest bridges are called “Web services,” by which Web islands automatically “feed” information to each other. In terms of convenience for human beings, Web services are a distinct advance over manually navigating Web pages. You can now set up a browser page or a desktop applet to “consume” (receive and display) a Web-feed of news headlines, stock quotes, weather information, package tracking, and so on. And that’s a good thing—a pleasant, time-saving, incremental improvement on yesterday’s way of doing things. But many people talk about Web services as “the next big thing,” and if that’s true we can only say: We were hoping for something bigger. Consuming a Web service is exactly the same thing as loading a Web page. The networked Dashboard Widgets in Apple’s Mac OS X, for example, are really little mini-browsers set up to hit Web URLs; you just don’t see them doing it. Web services are still prey to the client-server rigidity and vulnerability we’ve described, making them particularly unsuitable for vital public information services. And in order to concatenate information from diverse sources, Web services depend upon data-tagging conventions that require yet more layers of prior agreement, schemas, markup, and manual human administration. With each additional layer of such engineering and administration, the Web comes closer and closer to resembling a fantastically jury-rigged Rube Goldberg contraption. The reason is simple. The Web, with or without “services,” was not designed for a world driven by pervasive information flow. Why Do We Need the Information Commons When We Have Google? In its earliest days, the Web did not pretend to be the ultimate global information platform for all time. Its raison-d’être was more idiosyncratic and less glorious than that, though it was clearly a remarkable innovation—Everyman’s first hands-on experience of a global data network. Back then, hard-coded links were what added meta-value to the unstructured in© 2005 Harbor Research, Inc.

formation stored on the system. Human beings indexed the Web manually, with their eyes and hands, and well-maintained “jump pages” were the most valuable Web destinations. Those days didn’t last long, of course, but it’s important to remember what the Web was originally designed to be. Soon, automated indexing via search engines became essential. Those engines had names like AltaVista and Lycos, and when you searched for something, you got about 50,000 badly prioritized results, and you spent half your day barking up the wrong tree. Then came Google. It was started by some very smart people, and it produced vastly better results than the competition. Today, “Google” has become a verb and the company is among the most bankable in the world. If Google, or something else like it, had not arrived, humanity might have felt significantly less confident about depositing virtually all of its precious information on the system called the World Wide Web. But though it is a remarkable achievement, Google remains a blunt instrument, not a precision tool, for dealing with the world’s information. No matter how clever its indexing schemes and searching algorithms, Google cannot get around the fact that the Web does not store information in a fashion conducive to sophisticated retrieval and display. The Web can’t genuinely fuse data from multiple sources, and so Google can’t build an informationmodel that visualizes the answer to a complex, multi-dimensional question. Data Fusion: Information Wants to Be Free Information on the Web is not free (and that’s free as in “freedom,” not free as in “free of charge”). In fact, it’s closer to being imprisoned than it is to being genuinely liberated. Thanks to the client-server model, Web information is not free to move anywhere at will. And thanks to our present information architectures, it’s not free to merge with other information. What would truly liberated information be like? It might help to think of the atoms and molecules of the physical world. They have distinct identities, of course, but they are also capable of bonding with other atoms and molecules to create entirely different kinds of matter. Often this bonding requires special circumstances, such as extreme heat or pressure, but not always. In the world of information, such bonding is called “data fusion.” The special circumstances that provoke fusion might be nothing more than a user asking a certain multi-dimensional

question. And the newly created matter would be an easily perceivable, manipulable, or mappable “model” of the answer to that question. Here’s a geospatial example that already exists. In Pittsburgh, PA, USA, community development groups (in partnership with Carnegie Mellon University and the Brookings Institution), are importing a great variety of city-related datasets into MAYA’s Information Commons—from property assessment and land-use information to statistics on building permits and crime. Considered in isolation, none of these data would yield much more than we might get with conventional Web deployment. But MAYA’s leaders have a longstanding interest in civic computing and enhanced access to public information, so the Commons also already contains the location of every toxic waste site in the United States, as tracked by the EPA. Remember that all of these datasets were developed independently by entirely different agencies, and never consciously intended to be used together. But they all contain location information, often in the form of latitude and longitude. In the Information Commons, these shared attributes become fusion-points by which one can model the geographic relationship of, say, building permits to toxic waste sites, or land-use to crime. Any other shared attributes, such as calendar dates, could also be fusion-points between these datasets. And any other dataset of interest—the incidence of certain types of cancer, building-code violations, recreation areas, etc.—could also be fused into a visualizable information-model of the city or one of its neighborhoods. Facilitating data fusion is one of the fundamental purposes of MAYA’s Information Commons. Most people have had little, if any, experience with it, and so its power and importance are often difficult to grasp. The ability to perform true data fusion is the holy grail of information systems because it allows not only patterns but a whole higher order of intelligence to emerge from large collections of ordinary data. The implications for research in almost any area of human inquiry are obviously immense. The Commons uses an entirely new, schema-free database technology (we’ll discuss it in a moment) that avoids the confinements and limitations of relational databases. It allows data to maintain their fundamental identity while bonding freely with other data. Furthermore, the attributes of any data object can be changed or extended without changing any other. Even so, datasets rich in potential fusion-points are most desirable. Thus, there are best practices and recommended minimum attributes for most Commons data. In the case of building permits, for example, MAYA is working with the Brookings Institution to assess the © 2005 Harbor Research, Inc.

practices of many major cities in order to produce an ideal building-permit specification that reflects the accumulated wisdom of the profession at large. Cities and towns that adopt this specification will know, at a minimum, that their Commons-stored data will fuse well with building-permit data from anywhere else. Data in the Information Commons have strong inherent identity and a format that occupies a middle ground between unstructured and overly structured. A recommended set of attributes for a Commons data object or whole dataset is not the same thing as the rigid schemas of relational database tables, and does not lead to walled-off, non-interoperable information silos. Isn’t the information commons the same as the Semantic Web? Recognizing the need to share and fuse data from many diverse sources, the World Wide Web Consortium (W3C) launched an initiative some years ago called “the Semantic Web” whereby information stored in static pages and relational databases on servers can be “Webbed”—that is, made newly fluid and portrayable on the Web for both humans and machines. Many people who hear about MAYA’s Information Commons assume that it is another version of the Semantic Web, and thus redundant and unnecessary. The two visions may seem to have the same goal, but in fact they are profoundly different. The Semantic Web proposes to liberate data not by re-thinking basic information architecture or the machine-centric networking model, but by introducing a complex new layer of metadata (information about information). This is done with a markup language called RDF (Resource Description Framework) that describes the potential meanings and relationships (fusion-points) of a given piece of information in various contexts. RDF is the Semantic Web’s way of trying to add smartness to the inherently dumb Web. The Semantic Web does recognize the dilemma presented by the Web’s limitations, and it has many passionate proponents—perhaps precisely because it does not propose any particularly radical or disruptive steps. However, the Semantic Web has had very few real-world deployments. Besides being forbiddingly arcane and captive to existing Web technologies, RDF metadata often grows significantly larger than the data it is trying to describe. That last point has important negative implications for pervasive computing. Tim Berners-Lee, the inventor of the Web, has written that “one of the main driving forces for the Semantic Web has always been the expression, on the Web, of the vast amount of relational © 2005 Harbor Research, Inc.

database information in a way that can be processed by machines.” Even though he wrote that in 1998, Berners-Lee surely understood that “machines” could not mean simply human-operated PCs with the horsepower and the gigabytes of memory and storage required by billowing clouds of metadata around every single information object. Berners-Lee went on to say that “the goal of the semantic web is to express real life”—a completely admirable sentiment, but the “real life” of a global information space will involve the networking of many billions of comparably modest information devices, right down to such small but vital things as smoke detectors and burglar alarms. At the end of the day, the Semantic Web takes a step in the right direction, but it takes that step in a cumbersome way, without re-examining the Web’s underlying assumptions. It tries to fix a broken system with more engineering. The Information Commons, by contrast, imagines an Internet-connected world beyond the Web, and it does so with architectures that embrace every conceivable information device, however large or small. Like the Internet itself, a future-proofed global information system should be based upon fundamentally simple, extensible ideas. The Information Commons represents a shift to that sort of new paradigm. The Semantic Web represents an attempt to salvage the old paradigm. “Infotrons” and Information device Architecture (IDA) Radical new thinking about information technology must begin at the most basic levels, with new conceptions of information devices and of the fundamental unit of information itself. MAYA’s leaders attempt to future-proof their innovations in these areas by making the fewest possible assumptions about the nature of networked objects and the data they carry or process. Thus, the company takes a much broader, all-encompassing view of information devices (or “infotrons,” as they’re called) than is typically found in conventional computer science. Infotrons are the basic building blocks of MAYA’s Information Device Architecture (IDA). All infotrons have inputs and outputs, but little else about them is taken for granted. The essence of an infotron is completely abstracted from its real-world embodiment. In IDA, infotrons are fungible—that is, mutually interchangeable. From outside a properly designed infotron, there is no way to know whether it is hardware or software, because it doesn’t matter. Infotrons may, and often will, be capable of computing, but they don’t have to be.   Berners-Lee, “Web Design Issues: What a Semantic Web Can Represent.” © 2005 Harbor Research, Inc.

Indeed, an infotron doesn’t have to be electronic at all. If it’s capable of having information encoded within it, in any form, it’s an infotron. Infotrons also transmit information in a significantly different way from most distributed computing systems popular in industry today. IDA was designed from the ground up to let individual components communicate via “asynchronous message-passing,” which means that IDA-based designs tend to get better, not worse, as they scale. IDA encourages and rewards parallel computation, which is almost the same thing as “pervasive computing.” A Representation of “Infotrons” and MAYA’s Information Device Architecture (IDA)

In MAYA’s IDA, virtually any object that contains information—whether hardware or software—is an “infotron” that can be connected to any other. Source: MAYA Design, Inc.

In the past, the art of parallel computing has involved solving problems fast by getting lots of machines to work on what is essentially the same computation. With IDA, the art is to get machines to work together productively when their users have several different, independent, but overlapping information needs. People can work together in the Information Commons, and so parallel computing in the Commons is less about crunching one big problem than it is about facilitating complex collaboration.

not possible to move forward. The next great step in IT—completely fluid information and fully interoperating devices—requires an equally simple, flexible, and universal abstraction that will make information itself truly portable in both physical and information space, and among any conceivable information devices. A Representation of the Structure of U-Forms in MAYA’s VIA Repository

The attribute-value pairs of a u-form are arbitrarily extensible by users (though there are best practices that will maximize useful data-fusion). Note that a u-form can reference any other u-form by using its UUID as the value of an attribute. Source: MAYA Design, Inc.

As we have seen, chunks of information that lack structure or have too rigid a structure tend to live in isolation, unable to discover and bond with others to create new information. What’s required is a data-structure that provides unmistakable identity for every chunk of information but also facilitates flow and fusion. To this end, MAYA has built a new information architecture upon a universal data container called the “u-form.” All data and datarelationships in the Information Commons are stored in u-forms, not in relational database tables.   Lucas and Senn, “Toward the Universal Database,” p. 1. © 2005 Harbor Research, Inc.

The u-form is MAYA’s extension of the “e-form” proposed by the late Michael Dertouzos, longtime director of MIT’s computer science labs, who recognized that computing systems need a simple, extensible, and universal way to represent data. An e-form is simply a list of attribute-value pairs. Such pairs are not uncommon in computing, but until MAYA’s u-form they have not been used as the fundamental unit of information in a system.

15

To Dertouzos’s e-form MAYA has made one very important addition: a universally unique identifier (UUID). Thus the “u” of u-form. The UUID travels with the u-form’s data wherever in the world it may go, and in [We] take the radical, but ultimately whatever device it might find itself. Universally unique identifiers (UUIDs) Why does the new universal data container need a UUID? We all recognize the need for unique identifiers in many aspects of our lives and work. ISBN numbers for books, Social Security numbers for U.S. citizens, license plate numbers for automobiles, and so forth, allow us to refer unambiguously to a single object in some large population of objects. The aforementioned identifiers, however, are unique only in their own little worlds, not in the world at large. They are not universally unique. They operate within islands of reference, and they do not interoperate with other “islands.” They allow us to point unambiguously at an object in a given “namespace,” but nowhere else.

necessary, position that there is only one space of interoperating applications; therefore, at the end of the day there must be only one identity space. Until we come to terms with the implications of this simple claim, we will remain doomed to islands of context and systems that cannot interoperate.

“Mobile Devices and Mobile Data—Issues of Identity and Reference” —MAYA Design

In an unconnected or minimally connected world (a world of information islands), this works well enough most of the time. But MAYA is designing a system for a genuinely connected world in which there are no artificial barriers between pieces of information (data objects). In such a world, there is only one identity space—namely, Cyberspace—and thus the entities (information objects) that inhabit that space must be universally unique, not simply locally unique. Thus the absolute need for every data object to have a UUID. Establishing UUIDs for every piece of information in the world, however tiny or granular, will sound impossible to most people. In fact, technically speaking, it’s comparatively easy   Dertouzos, The Unfinished Revolution, p. 50.   Lucas and Senn, “Toward the Universal Database: U-forms and the VIA Repository,” p. 4.   Lucas, “The Trillion-Node Network,” p. 6. © 2005 Harbor Research, Inc.

to generate identifiers that virtually eliminate the possibility of “identity collision” for all time. MAYA Design did not invent the idea of UUIDs or the various techniques that exist today for generating them. But MAYA is unique in using UUIDs for u-forms, and thus placing them at the very heart of radically new information, storage, and device architectures.

The Visage Information Architecture (VIA) Whereas infotrons are the basic unit of MAYA’s device architecture called IDA, the u-form is the basic unit of a new approach to information itself, called the Visage Information Architecture (VIA). The name comes from MAYA software called Visage, which was an early manifestation of these ideas. Descendents of Visage include the commercial software tools we mentioned earlier, such as “Command Post of the Future,” now developed and supported by Viz (formerly MAYA Design’s sister company MAYA If we can achieve a universal identity Viz before its acquisition by General Dynamics C4 Systems). the name “Visage” suggests, information visualization space, we will have set the foundation As has always been one of MAYA’s key concerns.

for universal interoperability. It is difficult to see how we could make much progress toward this goal otherwise.

VIA is profoundly different from the information architectures in common use today, which one can see manifested in the schemas of relational database tables. Those inflexible, pre-ordained schemas impose more than rigid structure upon information. They impose rigid meaning. VIA, like “Mobile Devices and Mobile Data—Issues of Identity and IDA, is completely abstracted not only from the devices that Reference” —MAYA Design may transport or process data, but also from the schemas and layers of semantics that confer specific meaning upon data in specific contexts. VIA recognizes that database designers do not have—nor should they have—any idea of how specific data might be used in the near or distant future. Instead, VIA deals with the meaning of data when the data are retrieved for a specific purpose, not when they are stored. In other words, VIA does not make interpretive assumptions part of the basic unit of information itself. Doing this allows any datum to move throughout the system “atomically” as an irreducible entity, with no pre-defined role or absolute meaning imposed on it from birth. The resulting “data liquidity” allows these atoms of information to bond with others to form new information molecules that could not have been anticipated by the creators of the atoms © 2005 Harbor Research, Inc.

themselves. In VIA, irreducible units of information (u-forms) are free to play any number of “roles” and thus to be seen—literally “visualized”—in a wide variety of ways, something that MAYA calls “polymorphism.”

17

The VIA Repository: One Universal database The inexorable movement toward pervasive, distributed computing (“the network is the computer”) implies the existence of a equally pervasive, distributed store of knowledge that finally does away with all theoretical barriers between the world’s units of information. The u-form-based VIA makes this possible with a new kind of database technology in which uforms are the “records.” MAYA calls this storage architecture the VIA Repository. Above all else, the agenda implied Everything in the VIA Repository is represented by a u-form. Whole collections of u-forms (which might contain, for example, the result of a complex data-fusion) are themselves contained in a u-form, as are simpler u-form relationships. Each of the many possible “roles” that a u-form can play at retrieval time is also described by its own u-form, which might point to many other u-forms.

by the Universal Database requires a technique for unambiguously preserving the identity of each and every distinct data object wherever in the world its travels may take it. “Toward the Universal Database: U-forms and the VIA Repository” —MAYA Design

U-forms point to each other with absolute certainty by referring to their universally unique identifiers. For example, a “collection” u-form might have an attribute called “members”; the value of that attribute would be a list of the UUIDs of all the u-forms in the collection.

Specific implementations of the VIA Repository can be run on centralized servers, and the u-form-based storage architecture still provides the benefits of data liquidity and fusion. During the evolution of VIA, MAYA has done just this under numerous corporate and government contracts. This is also how many users, at first, will connect to the Information Commons with conventional Web browsers, mobile phones, etc. These end-user devices will not contain any Commons data or connect directly with each other. Everything will happen through servers. In this transitional form or mode, the full vision of the Commons is scaled back for compatibility with current technology. But the real power of the VIA Repository comes when it is freed from the client-server model and allowed to run in distributed form in a peer-to-peer (P2P) network. Thus, the Information Commons will ultimately resemble a system closer to Napster or Gnutella than to the © 2005 Harbor Research, Inc.

World Wide Web. In fact, the visionary of the Commons, MAYA’s co-founder Peter Lucas, sometimes whimsically calls it “Gnutella meets Encyclopedia Galactica.” In this full P2P mode, the Information Commons will run on a universal, distributed database that will be “everywhere and nowhere.” From the perspective of its users, this global implementation of the VIA Repository will be “the great database in the sky.” They won’t perceive (nor should they perceive) that its physical reality is in fact scattered throughout the world among all the peer devices that access the Commons—including their own. Shepherds and Replication The permanent, unique identity of u-forms has the paradoxical effect of allowing them to be in more than one place at the same time. If two u-forms have the same UUID, they are by definition the same u-form—that is, identical instances of the same u-form. A “copy” of a uform, by contrast, has a different UUID than the original, and can go on to have a separate life of its own. Since no information device can ever have direct, immediate access to the entire Information Commons, rules-based software agents called “shepherds” move replicates of u-forms to and from network nodes when a u-form’s data is requested by a user. The more “in demand” a given u-form is, the more it will be replicated throughout the system. Shepherds can be built or configured by users of the Commons to reflect their information interests. All u-forms can be annotated or commented upon by users, and unless a u-form is specifically protected, users can modify the actual content of u-forms, too. Because the system has this power, attentive readers will wonder how the replicates of a uform are kept in sync. If two replicates are changed at the same time, which one is authoritative? If someone requests that u-form, which replicate gets shepherded? There are a number of possible solutions, but one makes both social and technical sense. In the Commons, u-forms have “owners.” An arbitrarily large number of other people might make changes to a u-form, but those changes are not written to the u-form directly. Instead, they are considered tentative “suggestions” that the owner of the u-form has the power to “commit.” A Global Information Economy Financial economies that lack an abstracted, liquid currency are barter systems.

that transcends the inherent meaning of traded objects such as silk or grain or livestock. The idea of a liquid currency was a paradigm-shifting innovation in running an economic system. All of MAYA’s thinking about information economy and device ecology is predicated upon the very same idea, with the same revolutionary implications.

19

The common “currencies” of the bit, the byte, and the packet made massive and rapid evolution possible in computing and networking. In MAYA’s Information Device Architecture (IDA), the basic unit of currency is the infotron, which makes information devices truly fungible (mutually interchange- On the one hand, there is a clear able). In the Visage Information Architecture (VIA), the need for some kind of ubiquitous basic unit of currency is the u-form, which creates true data liquidity. All these concepts—currency, liquidity, and fungi- standardization on a grand scale. bility—are quite deliberately borrowed from economics. On the other hand, the need for What is the common currency of the Web world? Is it unbounded scalability places HTML? XML? The Web “page”? The relational database stringent restrictions on the use of table? The hard truth is that the Web has no common currency for information or information devices. As a platform for central authorities of any kind. “The Trillion-Node Network” —MAYA Design “the world’s information” (the phrase used in Google’s mission statement), the Web resembles a comparatively primitive barter system of “apples and oranges,” not a sophisticated economy. Pervasive computing implies a true global information economy. Device fungibility and data liquidity are its essential requirements—remarkably simple foundations for intense complexity that remains comprehensible and useful at any scale. Peer-to-Peer Is Not Evil We will not be surprised if the mention of “peer-to-peer” has struck fear in the hearts of some of our readers. If so, we hope it has not entirely closed their minds. The business world has had some well-publicized experience with peer-to-peer networks—notably in the form of the Napster file-sharing software and its ilk—and that experience is often portrayed as traumatic (even if it really wasn’t). Because this type of file-sharing software was infamously used to pirate copyrighted works, the entire category of P2P has come to be unjustly tarred with the brush of “hacker crime.” The entertainment industry in particular has gone after P2P with a vengeance, in some cases lobbying lawmakers to try to outlaw P2P altogether. The latest example is the June, © 2005 Harbor Research, Inc. All rights reserved. http://harborresearch.com/ [email protected] • 800.595.9368 • 415.615.9400

2005 Supreme Court decision in the case of MGM vs. Grokster. But though this decision was technically a victory for the plaintiffs, it was in no way a condemnation of P2P itself. The decision simply said that if the owners of a P2P system actively encourage illegal behavior, they can be held liable for that behavior. The Information Commons does not encourage illegal sharing, and in fact it makes extensive provisions for the protection of intellectual property. For the pervasive computing era, P2P networking makes vastly better sense than the clientserver model. Indeed, it’s the only viable alternative. MAYA’s leadership views P2P as essential to the realization of the true potential of Cyberspace—the ability to use information to benefit humanity in ways not even imaginable today. Intellectual Property and a New Information culture Even though the blanket indictment of P2P by some business leaders has been wrongheaded and reactionary, it is also true that no sane thinking about the future of information can take place without allowing for the protection of intellectual property. Everyone, but especially commercial entities, will be relieved to hear that MAYA has given this subject intense and detailed attention. The Information Commons is presently populated primarily with publicly available data. As its first proof-of-concept, it aims to enable a new era of civic computing. But proprietary information intended for authorized participants or paying customers can and will co-exist in the Commons alongside public information. How will intellectual property be protected? Some technologists view P2P networking and data security as fundamentally at odds with each other, perhaps even mutually exclusive. MAYA strongly rejects this view, and has incorporated a number of mechanisms into the Commons for accountability, authentication, and security. First, the strong identity of every u-form (via UUIDs) makes it easier than ever before to demonstrate diligence in protecting intellectual property, and to identify blatant violations. Second, the intellectual property status of any bit of Commons data can be easily marked, and at a fine level of granularity. For example, some u-forms in a dataset can be declared to be fully in the public domain, while others in the very same dataset are declared to be owned by their creators and to have some or all rights reserved. No other system today offers a practical way to do this. © 2005 Harbor Research, Inc. All rights reserved. http://harborresearch.com/ [email protected] • 800.595.9368 • 415.615.9400

MAYA wishes to foster an information culture based upon a reasonable degree of sharing, and so it encourages authors and publishers to adopt the Creative Commons designation “some rights reserved” wherever possible, rather than compulsively marking everything “all rights reserved.” But the Information Commons is by no means limited to the Creative Commons philosophy (http://creativecommons.org). Third, it is easy to digitally sign any u-form so that users can verify cryptographically that its contents have not changed since it was signed by its publisher (the entity that vouches for the information), even if it has subsequently passed through many P2P “hands.” Individual users of the Commons can also declare that they do not want data shepherded to their devices unless those data have a certain intellectual property and/or signature status. Fourth, the entire contents of individual u-forms can be protected via strong encryption for those who wish to charge for the use of data, or to limit accessibility to privileged users. Again, protected and unprotected u-forms can mingle in the same dataset. MAYA Design welcomes inquiries from any organization, non-profit or commercial, that wishes to explore participation in the Information Commons. Humanservices.net: A Commons/Web Hybrid In IDA and VIA, end-user devices are seen as “transducers” for receiving, processing, and visualizing data. They are simply the means by which human beings experience something that is inherently invisible to them: digital information. If information in the Commons is really free to flow and fuse and manifest itself in any “transducer,” then the conventional Web browser certainly qualifies. This makes for a nuanced, subtle story in which MAYA is inventing a potential alternative to the Web that can also play well with the Web itself. As we said earlier, the Information Commons is a disruption that will succeed partly by making a graceful transition possible. In fact, MAYA is undertaking a number of Commons-based initiatives, both commercial and non-profit, designed to be experienced, at least initially, on the Web. One such Commons/Web hybrid can be seen today in “preview” form at http://www.humanservices.net/. This project, done for Pennsylvania’s Allegheny County, fuses county databases with those of the United Way charitable organization. Formerly, these two entities maintained separate and largely redundant collections of data on human services available in the same geographic area.

Besides the obvious waste of maintaining two sets of similar data, most of the information was not even available to workers online because the agencies could not find a solution to fusing their datasets. The humanservices.net initiative gave them not only fused data, but a Web application that embodies some of the “information-centric” user-interface features of MAYA’s sophisticated stand-alone software.

personal crises, the agencies periodically take humanservices.net offline to fix the data problems that have surfaced. All initial forays into data-fusion are likely to produce a similar experience. Fusion reveals previously unperceived qualities of the underlying information—both positive and negative. No matter how sophisticated, information systems produce high-quality results only if they have high-quality underlying data. Civium Workbench: The First Information Commons Application If the Information Commons can be experienced—at least to some degree—on the Web, what happens when it’s not? How do you leave the client-server world behind, embrace P2P, and leap wholeheartedly into MAYA’s great database in the sky? To do that, you need to be running a peer-to-peer Internet application that connects you to every other “user” of the Commons (which does not necessarily imply the existence of a human being). Part of this application will be a software toolset for reading, visualizing, and authoring Commons data. An equally important part of it will be a P2P version of the VIA Repository installed on your own device (personal computer or otherwise). That’s what makes you part of the great database. Many such Commons applications are possible. In the future, they will come from a variety of developers. But the first one, Civium Workbench, is pure MAYA Design. Like the browser-based application at humanservices.net, Workbench features an information-centric interface that lets users interact with data as directly as possible. Information-centric interfaces get this power from u-forms, and are the result of many years of user-experience and human-computer-interaction research at MAYA. The Java-based Workbench, however, goes well beyond what can be done with the HTML and JavaScript that Web browsers use. Notably, it gives users the power of “polymorphism”— the ability to display liquid, fuseable data in many different ways at will, depending upon the qualities available in the u-forms involved. Using Workbench, you might drag certain bars of a bar chart onto a map to see them displayed geographically. (The bar chart and the map simply display different attributes of the same underlying u-forms.) You might then drag some of those mapped points onto a table, or a scatter-chart, or even onto a mediaplayer widget if those u-forms happen to possess audio or video attributes (or point to other u-forms that do).

Civium Workbench allows data-visualization in space and time simultaneously. You might manipulate an on-screen slider to portray on a map the relationship of toxic waste sites to cancer incidence as it has changed over the last decade—watching the map update as you slide through the years. Thanks to u-forms and VIA, the geospatial capabilities of Workbench exceed those of most commercial GIS applications available today. Some public agencies have longstanding programs to collect photographic data on communities. With such data imported into the Commons, you might, for instance, use Workbench to “drive” down a certain street in 1990, 1995, or 2002, seeing exactly how it has been transformed.

“Civium,” incidentally, is Latin for “of the people,” and refers to the flowering of civic computing that MAYA hopes to engender with the Commons. One of core elements of the company’s culture is the belief that it can be financially profitable while also serving the public good. In the future, MAYA expects to launch non-profit and commercial ventures that use the Civium brand.

Networking and “Emergent intelligence” The dot-com mantra “the Internet changes everything” was wrong. It was wrong partly because it was not referring to the Internet itself, but to the World Wide Web, without acknowledging the difference. The Web changed many things, but hardly everything. And many of the changes the Web did make are Any organization scheme simply not designed well enough to be permanent. But the mantra was also wrong in referring to the Internet, because that suggests an arbitrary limit on its significance. The phrase should have been “networking changes everything.”

that requires each device to receive any individual attention whatsoever in order to join the network is simply precluded.

That’s a mantra worth chanting because it applies to the neurons of “The Trillion Node Network” —MAYA Design the brain, or ants in an anthill, or human beings in a society, as well as information devices connected to each other. The many “nodes” of a network may not be very “smart” in themselves, but if they are networked in a way that allows them to connect effortlessly and interoperate seamlessly, they begin to give rise to complex, system-wide behavior that usually goes by the name “emergence.” That is, an entirely new order of intelligence “emerges” from the system as a whole—an intelligence that could not have been predicted by looking at any of the nodes individually. There’s a distinct magic to emergence, but it happens only if the network’s nodes are free to share information and processing power. The realization of the Pervasive Internet will involve billions upon billions of protean network nodes that ultimately “take on a life of their own.” Our present-day conception of “intelligent devices” and global data networking does not allow for that. Until we change that situation, we will not achieve the emergent magic implied by the phrase “the network is the computer.” All of this discussion—about the Web’s limitations and the great virtues of MAYA Design’s big ideas—has really been about that.

Internet 0 A Zero-infrastructure ad-hoc network The Pervasive Internet holds the potential for what Harbor Research calls “the networking of every manufactured thing.” MAYA Design’s Information Commons incorporates the necessary device and information architectures, but it also presupposes the existence of “a zero-infrastructure, ad-hoc network” that makes seamless physical connection possible.10

Internet 0 is an emerging alternative [to other means of device connectivity] that simplifies and unifies the physical side of Internet access by using something like a Morse code for the Internet. —Neil Gershenfeld, Fab

How will the physical aspects of this networking actually take place? How will virtually any device, right down to a lowly light bulb, become a peer that connects at will to the global data network? Obviously, billions of devices of wildly varying types cannot each receive individual attention and configuration, or conform to elaborate a priori specifications. If it literally takes a network engineer to screw in a smart light bulb, pervasive computing is never going to work. Many schemes and so-called “standards” for device connectivity already exist. But of course, all those “solutions” add up to one big problem. We don’t want many standards; we want one.

An elegant answer is offered by the “Internet 0” (I0) initiative from MIT’s Center for Bits and Atoms (CBA). I0 is predicated upon the idea that we already have an excellent way to get every conceivable device on the Internet—the original design principles and protocols of the Internet itself. What the Internet Really Is “Internet” is short for “internetworking.” The Internet was designed in the 1960s to allow the incompatible data networks and computing systems of the time to share information— to “talk to each other,” as people like to say. The Internet is literally a “network of networks.” That’s what the “inter” means.11 The public Internet as we know it today is a worldwide embodiment of those original data communications protocols—which are, by design, extremely simple. For this discussion,

their key attribute is that they make very few assumptions about the data they are sending and about the devices connecting to the network to send and receive data. It is this extensible, technology-neutral basis of the Internet that has allowed it to scale so dramatically (and gracefully) since its inception, with minimal central administration. Back to the Future CBA’s name explains its mission—the convergence of the physical world of atoms and the computing world of bits. Like MAYA Design, it’s an inter-disciplinary organization; its members come from many departments at MIT. CBA’s director, Neil Gershenfeld, teaches physics at MIT when he’s not embedding sensors in Yo-Yo Ma’s cello or building “fab labs” where people can “print out” such things as real working bicycles from their laptops.

There are twenty or so other standards aimed, like Internet 0, at networking embedded devices rather than general-purpose computers: CAN, LIM, BACnet, CEBus, LonWorks, X10, USB, Bluetooth, SPI, I2C, etc. These all share one feature: incompatibility.

Internet 0 is a back-to-the-future story. Just as the Internet’s “internetworking” united disparate networks, I0 uses the same design principles for “interdevice internetworking”—uniting disparate devices. Doing this requires a return to first principles. Thus the “zero.” I0’s name began as a whimsical response to the high-speed “Internet 2” project, which aims to supplant the present-day Internet (Internet 1) and enable ever more bandwidth-intensive human-centric services such as IP-based television.

Internet 2 is all about speed and “big pipes” aimed at the senses of human beings. I0, by contrast, aims to create an “Internet of Things,” and things do not typically watch high-definition movies on demand. They don’t need lots of speed and bandwidth, but they do need to connect effortlessly and interoperate seamlessly. The Physics of Bits To make most everyday objects connect and interoperate with the least engineering, high speed is not only unnecessary, it’s bad. The reason is found in physics, something that most IT professionals don’t think about very much. Bits have a physical size. The slower the speed of transmission, the bigger the bit. Very fast, very small bits cover an entire building in a tiny fraction of a second, and then scatter, requiring specialized network interfaces to capture them. But a slower bit as big as the Ritz can embrace—physically—all the devices in the building, from light bulbs and wall switches up to the commercial AC on the roof. When © 2005 Harbor Research, Inc.

a bit is that big, it transcends the need for specialized, expensive, incompatible network infrastructure.12

(And when we say “slow,” by the way, we don’t mean slow like a snail. At a data rate of a megabit per second—the speed of most cable modems or DSL connections—a bit is about 300 meters long—big enough to encompass most An Internet 0 Processor buildings.) I0’s creators (one of whom, Danny Cohen, was a father of the Internet itself) liken it to Morse Code, by which the very same message can be blinked with a flashlight, pounded with a hammer, or sent as electrical impulses. The transmission medium doesn’t matter. Instead of the “short” and “long” pulses of Morse Code, I0 uses the 0s and 1s of an IP packet, but defines times for representing them rather than the voltages used by other serial transmission methods.

A full, working implementation of Internet Protocol exists on this tiny processor. It is a self-standing, full-fledged Internet node. Source: MIT Center for Bits and Atoms

Just as the Internet uses the “end-to-end” principle to remain agnostic about what is connected to it, I0 extends that principle to “end-to-end modulation.” Modulation refers to the physical representation of information. Like Morse Code, I0 doesn’t care about the medium in which messages are sent.

Embedding the Internet into the World I0 literally incorporates the Internet into physical infrastructure, making something like a “smart building” much easier to contemplate than ever before. The building itself is literally on the Internet and the Internet is in the very matter of the building. If this is such a good idea, why hasn’t it been done before? Much current IT practice in this area is a holdover from the early days of networking when bandwidth was precious and implementing a TCP/IP “stack” in a small device involved unthinkable overhead. That situation has changed, of course. Furthermore, I0’s creators re12  Gershenfeld, et al., “The Internet of Things,” p. 80. © 2005 Harbor Research, Inc.

alized that a lot of typical stack code exists to perform administrative functions that are not strictly necessary in real-world, lightweight implementations like I0. “The code to run IP can be squeezed into a few kilobytes and run on a one-dollar microcontroller.”13

As in MAYA’s Information Commons, I0-enabled objects live in a peer-to-peer model. Servers can add value to some I0 implementations, but they are not required by the architecture. Like the “infotrons” at the heart of MAYA’s Information Device Architecture (IDA), I0 objects can be anything with information encoded in Internet 0 trades optimality them, right down to a non-electronic house key. And like the u-forms of for simplicity and generality, MAYA’s Visage Information Architecture (VIA), I0 objects maintain which are as sorely needed their own identity with universally unique identifiers. Each message sent by an I0 processor carries its own IP header. “The IP information adds about 100 bits to each message, which typically has a negligible impact on the response time and power requirements. In return for this modest overhead, the network avoids the cost of configuring and maintaining complex interfaces.”14

in information technology as they are in the rest of the world.

—Neil Gershenfeld, Fab

Internet 0 is a universal alternative to the many existing techniques for connecting ordinary devices to the Internet. The other techniques all have something to recommend them; each is optimized for a special purpose. But in return for their optimality, they sacrifice compatibility. Since most device connectivity rarely requires maximum optimality, compatibility is a much more important objective, and thus Internet 0 makes its trade-offs to that end. An Internet 0 Packet in the Form of a Printed Bar Code

This is not a representation of an Internet 0 message, it is an I0 message. The vertical bars represent pulses. Converted into electrical impulses by a barcode reader, they can be put on the Internet with no further translation. The IP information adds only about 100 bits to the message, which, in this case, says “Hello.” Source: MIT Center for Bits and Atoms

Conclusion A Return to First Principles The developers of the Information Commons and Internet 0 have not worked together, but they have arrived at remarkably similar and complementary conclusions. In both cases, the conscious insistence on a multi-disciplinary approach seems to have been a key ingredient in allowing them to see past the fixed ideas of current computer science. MAYA’s IDA and VIA, and CBA’s “Morse Code for the Internet” both succeed with a “return to first principles” and by creating architectures that make the fewest possible assumptions about devices and data and how they will be used in the future. Together, they underscore the need to build simple, extensible foundations for intense complexity. To many readers, these ideas will seem too good to be true. More to the point, they will seem too simple to be good. But that is the point. 3
