A wiki (/ˈwɪki/ ( listen) WIK-ee) is a website on which users collaboratively modify content and structure directly from the web browser. In a typical wiki, text is written using a simplified markup language and often edited with the help of a rich-text editor.[1] A wiki is run using wiki software, otherwise known as a wiki engine. A wiki engine is a type of content management system, but it differs from most other such systems, including blog software, in that the content is created without any defined owner or leader, and wikis have little inherent structure, allowing structure toThe Indian Premier League (IPL) is a professional Twenty20 cricket league in India contested during April and May of every year by 8 teams representing 8 cities of India.[3] The league was founded by the Board of Control for Cricket in India (BCCI) in 2008, and is regarded as the brainchild of Lalit Modi, the founder and former commissioner of the league.[4] IPL has an exclusive window in ICC Future Tours Programme.[5] The IPL is the most-attended cricket league in the world and in 2007 ranked sixth by average attendance among all sports leagues.[6] In 2010, the IPL became the first sporting event in the world to be broadcast live on YouTube.[7][8] The brand value of IPL in 2018 was US$6.3 billion, according to Duff & Phelps.[9] According to BCCI, the 2015 IPL season contributed ₹12,543.5 billion (US$182 million) to the GDP of the Indian economy.[10] There have been eleven seasons of the IPL tournament. The current IPL title holders are the Chennai Super Kings, who won the 2018 season.

History[edit]

Background[edit] The Indian Cricket League (ICL) was founded in 2007, with funding provided by Zee Entertainment Enterprises.[11] The ICL was not recognised by the Board of Control for Cricket in India (BCCI) or the International Cricket Council (ICC) and the BCCI were not pleased with its committee members joining the ICL executive board.[12] To prevent players from joining the ICL, the BCCI increased the prize money in their own domestic tournaments and also imposed lifetime bans on players joining the ICL, which was considered a rebel league by the board.[13][14]

Foundation[edit] "The IPL has been designed to entice an entire new generation of sports fans into the grounds throughout the country. The dynamic Twenty20 format has been designed to attract a young fan base, which also includes women and children." — Modi during the launch of the IPL.[15]

On 13 September 2007, the BCCI announced the launch of a franchise-based Twenty20 cricket competition called Indian Premier League whose first season was slated to start in April 2008, in a "high-profile ceremony" in New Delhi. BCCI vice-president Lalit Modi, said to be the mastermind behind the idea of IPL, spelled out the details of the tournament including its format, the prize money, franchise revenue system and squad composition rules. It was also revealed that the IPL would be run by a seven-man governing council composed of former India players and BCCI officials, and that the top two teams of the IPL would qualify for that year's Champions League Twenty20. Modi also clarified that they had been working on the idea for two years and that IPL was not started as a "knee-jerk reaction" to the ICL.[15] The league's format was similar to that of the Premier League of England and the NBA in the United States.[14] In order to decide the owners for the new league, an auction was held on 24 January 2008 with the total base prices of the franchises costing around $400 million.[14] At the end of the auction, the winning bidders were announced, as well as the cities the teams would be based in: Bangalore, Chennai, Delhi, Hyderabad, Jaipur, Kolkata, Mohali, and Mumbai.[14] In the end, the franchises were all sold for a total of $723.59 million.[16] The Indian Cricket League soon folded in 2008.

Expansions and terminations[edit]

On 21 March 2010, it was announced that two new franchises – Pune Warriors India and Kochi Tuskers Kerala – would join the league before the fourth season in 2011.[17] Sahara Adventure Sports Group bought the Pune franchise for $370 million while Rendezvous Sports World bought the Kochi franchise for $333.3 million.[17] However, one year later, on 11 November 2011, it was announced that the Kochi Tuskers Kerala side would be terminated following the side breaching the BCCI's terms of conditions.[18] Then, on 14 September 2012, following the team not being able to find new owners, the BCCI announced that the 2009 champions, the Deccan Chargers, would be terminated.[19] The next month, on 25 October, an auction was held to see who would be the owner of the replacement franchise, with Sun TV Networkwinning the bid for the Hyderabad franchise.[20] The team would be named Sunrisers Hyderabad.[21]

Pune Warriors India withdrew from the IPL on 21 May 2013 over financial differences with the BCCI.[22] The franchise was officially terminated by the BCCI, on 26 October 2013, on account of the franchise failing to provide the necessary bank guarantee.[23] On 14 June 2015, it was announced that two-time champions, Chennai Super Kings, and the inaugural season champions, Rajasthan Royals, would be suspended for two seasons following their role in a match-fixing and betting scandal.[24] Then, on 8 December 2015, following an auction, it was revealed that Pune and Rajkot would replace Chennai and Rajasthan for two seasons.[25] The two teams were the Rising Pune Supergiant and the Gujarat Lions.

Organization[edit] Tournament format[edit] Currently, with eight teams, each team plays each other twice in a home-and-away roundrobin format in the league phase. At the conclusion of the league stage, the top four teams will qualify for the playoffs. The top two teams from the league phase will play against each other in the first Qualifying match, with the winner going straight to the IPL final and the loser getting another chance to qualify for the IPL final by playing the second Qualifying match. Meanwhile, the third and fourth place teams from league phase play against each other in an eliminator match and the winner from that match will play the loser from the first Qualifying match. The winner of the second Qualifying match will move onto the final to play the winner of the first Qualifying match in the IPL Final match, where the winner will be crowned the Indian Premier League champions.

Player acquisition, squad composition and salaries[edit] A team can acquire players through any of the three ways: the annual player auction, trading players with other teams during the trading windows, and signing replacements for unavailable players. Players sign up for the auction and also set their base price, and are bought by the franchise that bids the highest for them. Unsold players at the auction are eligible to be signed up as replacement signings. In the trading windows, a player can only be traded with his consent, with the franchise paying the difference if any between the old and new contract. If the new contract is worth more than the older one, the difference is shared between the player and the franchise selling the player. There are generally three trading windows–two before the auction, and one after the auction but before the start of the tournament. Players can not be traded outside the trading windows or during the tournament, whereas replacements can be signed before or during the tournament. Some of the team composition rules (as of 2018 season) are as follows:    

The squad strength must be between 18 and 25 players, with a maximum of 8 overseas players. Salary cap of the entire squad must not exceed ₹80 crore.[26] Under-19 players can not be picked unless they have previously played first-class or List A cricket. A team can play a maximum of 4 overseas players in their playing eleven.[27]

The term of a player contract is one year, with the franchise having the option to extend the contract by one or two years. Since the 2014 season, the player contracts are denominated in the Indian rupee, before which the contracts were in U.S. dollars. Overseas players can be remunerated in the currency of the player's choice at the exchange rate on either the contract due date or the actual date of payment.[28] Prior to the 2014 season, Indian domestic players were not included in the player auction pool and could be signed up by the franchises at a discrete amount while a fixed sum of ₹10 to 30 lakhwould get deducted per signing from the franchise's salary purse. This received significant opposition from franchise owners who complained that richer franchises were "luring players with under-the-table deals" following which the IPL decided to include domestic players in the player auction.[29]

According to a 2015 survey by Sporting Intelligence and ESPN The Magazine, the average IPL salary when pro-rated is US$4.33 million per year, the second highest among all sport leagues in the world. Since the players in IPL are only contracted for the duration of the tournament (less than two months), the weekly IPL salaries are extrapolated pro rata to obtain average annual salary, unlike other sport leagues in which players are contracted by a single team for the entire year.[30]

Match rules emerge according to the needs of the users.[2] There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems. Some wiki engines are open source, whereas others are proprietary. Some permit control over different functions (levels of access); for example, editing rights may permit changing, adding, or removing material. Others may permit access without enforcing access control. Other rules may be imposed to organize content. The online encyclopedia project Wikipedia is the most popular wiki-based website, and is one of the most widely viewed sites in the world, having been ranked in the top ten since 2007.[3] Wikipedia is not a single wiki but rather a collection of hundreds of wikis, with each one pertaining to a specific language. In addition to Wikipedia, there are tens of thousands of other wikis in use, both public and private, including wikis functioning as knowledge management resources, notetaking tools, community websites, and intranets. The Englishlanguage Wikipedia has the largest collection of articles; as of September 2016, it had over five million articles. Ward Cunningham, the developer of the first wiki software, WikiWikiWeb, originally described wiki as "the simplest online database that could possibly work".[4] "Wiki" (pronounced [ˈwiki][note 1]) is a Hawaiian word meaning "quick".[5][6][7]

Ward Cunningham, inventor of the wiki

Ward Cunningham and co-author Bo Leuf, in their book The Wiki Way: Quick Collaboration on the Web, described the essence of the Wiki concept as follows:[8]   

A wiki invites all users—not just experts—to edit any page or to create new pages within the wiki Web site, using only a standard "plain-vanilla" Web browser without any extra add-ons. Wiki promotes meaningful topic associations between different pages by making page link creation intuitively easy and showing whether an intended target page exists or not. A wiki is not a carefully crafted site created by experts and professional writers, and designed for casual visitors. Instead, it seeks to involve the typical visitor/user in an ongoing process of creation and collaboration that constantly changes the website landscape.

A wiki enables communities of editors and contributors to write documents collaboratively. All that people require to contribute is a computer, Internet access, a web browser, and a basic understanding of a simple markup language (e.g., HTML). A single page in a wiki website is referred to as a "wiki page", while the entire collection of pages, which are usually wellinterconnected by hyperlinks, is "the wiki". A wiki is essentially a database for creating, browsing, and searching through information. A wiki allows non-linear, evolving, complex, and networked text, while also allowing for editor argument, debate, and interaction regarding the content and formatting.[9] A defining characteristic of wiki technology is the ease with which pages can be created and updated. Generally, there is no review by a moderator or gatekeeper before modifications are accepted and thus lead to changes on the website. Many wikis are open to alteration by the general public without requiring registration of useraccounts. Many edits can be made in real-time and appear almost instantly online, but this feature facilitates abuse of the system. Private wiki servers require user authentication to edit pages, and sometimes even to read them. Maged N. Kamel Boulos, Cito Maramba, and Steve Wheeler write that the open wikis produce a process of Social Darwinism. "'Unfit' sentences and sections are ruthlessly culled, edited, and replaced if they are not considered 'fit', which hopefully results in the evolution of a higher quality and more relevant page. While such openness may invite 'vandalism' and the

posting of untrue information, this same openness also makes it possible to rapidly correct or restore a 'quality' wiki page."[10]

Some wikis have an Edit button or link directly on the page being viewed, if the user has permission to edit the page. This can lead to a text-based editing page where participants can structure and format wiki pages with a simplified markup language, sometimes known as Wikitext, Wiki markup or Wikicode (it can also lead to a WYSIWYG editing page; see the paragraph after the table below). For example, starting lines of text with asterisks could create a bulleted list. The style and syntax of wikitexts can vary greatly among wiki implementations,[example needed] some of which also allow HTML tags. Wikis have favoured plain-text editing, with fewer and simpler conventions than HTML, for indicating style and structure. Although limiting access to HTML and Cascading Style Sheets (CSS) of wikis limits user ability to alter the structure and formatting of wiki content, there are some benefits. Limited access to CSS promotes consistency in the look and feel, and having JavaScript disabled prevents a user from implementing code that may limit other users' access.

Wikis can also make WYSIWYG editing available to users, usually by means of JavaScript control that translates graphically entered formatting instructions into the corresponding HTML tags or wikitext. In those implementations, the markup of a newly edited, marked-up version of the page is generated and submitted to the server transparently, shielding the user from this technical detail. An example of this is the VisualEditor on Wikipedia. WYSIWYG controls do not, however, always provide all of the features available in wikitext, and some users prefer not to use a WYSIWYG editor. Hence, many of these sites offer some means to edit the wikitext directly. Some wikis keep a record of changes made to wiki pages; often, every version of the page is stored. This means that authors can revert to an older version of the page should it be necessary because a mistake has been made, such as the content accidentally being deleted or the page has been vandalized to include offensive or malicious text or other inappropriate content. Many wiki implementations, such as MediaWiki, allow users to supply an edit summary when they edit a page. This is a short piece of text summarizing the changes they have made (e.g., "Corrected grammar," or "Fixed formatting in table."). It is not inserted into the article's main text, but is stored along with that revision of the page, allowing users to explain what has been done and why, similar to a log message when making changes in a revision-control system. This enables other users to see which changes have been made by whom and why, often in a list of summaries, dates and other short, relevant content, a list which is called a "log" or "history."

Navigation Within the text of most pages, there are usually a large number of hypertext links to other pages within the wiki. This form of non-linear navigation is more "native" to a wiki than structured/formalized navigation schemes. Users can also create any number of index or tableof-contents pages, with hierarchical categorization or whatever form of organization they like. These may be challenging to maintain "by hand", as multiple authors and users may create and delete pages in an ad hoc, unorganized manner. Wikis can provide one or more ways to categorize or tag pages to support the maintenance of such index pages. Some wikis, including the original, have a backlink feature, which displays all pages that link to a given page. It is also typically possible in a wiki to create links to pages that do not yet exist, as a way to invite others to share what they know about a subject new to the wiki. Wiki users can typically "tag" pages with categories or keywords, to make it easier for other users to find the article. For example, a user creating a new article on cold weather cycling might "tag" this page under the categories of commuting, winter sports and bicycling. This would make it easier for other users to find the article.

Linking and creating pages Links are created using a specific syntax, the so-called "link pattern". Originally, most wikis[citation needed] used CamelCase to name pages and create links. These are produced by capitalizing

words in a phrase and removing the spaces between them (the word "CamelCase" is itself an example). While CamelCase makes linking easy, it also leads to links in a form that deviates from the standard spelling. To link to a page with a single-word title, one must abnormally capitalize one of the letters in the word (e.g. "WiKi" instead of "Wiki"). CamelCase-based wikis are instantly recognizable because they have many links with names such as "TableOfContents" and "BeginnerQuestions." It is possible for a wiki to render the visible anchor of such links "pretty" by reinserting spaces, and possibly also reverting to lower case. This reprocessing of the link to improve the readability of the anchor is, however, limited by the loss of capitalization information caused by CamelCase reversal. For example, "RichardWagner" should be rendered as "Richard Wagner", whereas "PopularMusic" should be rendered as "popular music". There is no easy way to determine which capital letters should remain capitalized. As a result, many wikis now have "free linking" using brackets, and some disable CamelCase by default.

Searching Most wikis offer at least a title search, and sometimes a full-text search. The scalability of the search depends on whether the wiki engine uses a database. Some wikis, such as PmWiki, use flat files.[11]MediaWiki's first versions used flat files, but it was rewritten by Lee Daniel Crocker in the early 2000s (decade) to be a database application. Indexed database access is necessary for high speed searches on large wikis. Alternatively, external search engines such as Google Search can sometimes be used on wikis with limited searching functions in order to obtain more precise results.

History Main article: History of wikis

Wiki Wiki Shuttle at Honolulu International Airport

WikiWikiWeb was the first wiki.[12] Ward Cunningham started developing WikiWikiWeb in Portland, Oregon, in 1994, and installed it on the Internet domain c2.com on March 25, 1995. It was named by Cunningham, who remembered a Honolulu International Airport counter employee telling him to take the "Wiki Wiki Shuttle" bus that runs between the airport's terminals. According to Cunningham, "I chose wiki-wiki as an alliterative substitute for 'quick' and thereby avoided naming this stuff quick-web."[13][14] Cunningham was, in part, inspired by Apple Inc.'s HyperCard, which he had used. HyperCard, however, was single-user.[15] Apple had designed a system allowing users to create virtual "card stacks" supporting links among the various cards. Cunningham developed Vannevar Bush's ideas by allowing users to "comment on and change one another's text."[1][16] Cunningham says his goals were to link together people's experiences to create a new literature to document programming patterns, and to harness people's natural desire to talk and tell stories with a technology that would feel comfortable to those not used to "authoring".[15] Wikipedia became the most famous wiki site, entering the top ten most popular websites in 2007. In the early 2000s (decade), wikis were increasingly adopted in enterprise as collaborative software. Common uses included project communication, intranets, and documentation, initially for technical users. Some companies use wikis as their only collaborative software and as a replacement for static intranets, and some schools and universities use wikis to enhance group

learning. There may be greater use of wikis behind firewalls than on the public Internet. On March 15, 2007, the word wiki was listed in the online Oxford English Dictionary.[17]

Alternative definitions In the late 1990s and early 2000s, the word "wiki" was used to refer to both user-editable websites and the software that powers them; the latter definition is still occasionally in use.[2] Wiki inventor Ward Cunningham wrote in 2014[18] that the word "wiki" should not be used to refer to a single website, but rather to a mass of user-editable pages and or sites, so that a single website is not "a wiki" but "an instance of wiki". He wrote that the concept of wiki federation, in which the same content can be hosted and edited in more than one location in a manner similar to distributed version control, meant that the concept of a single discrete "wiki" no longer made sense.[19]
