

The author or holder of the license of the source code cannot collect royalties on the distribution of the program The distributed program must make the source code accessible to the user The author must allow modifications and derivations of the work under the program's original name No person, group or field of endeavor can be denied access to the program The rights attached to the program must not depend on the program's being part of a particular software distribution The licensed software cannot place restrictions on other software that is distributed with it.

OPEN SOURCE SOFTWARE & FREE SOFTWARE  The

Free Software movement is working toward the goal of making all software free of intellectual property restrictions. Followers of this movement believe these restrictions hamper technical improvement and work against the good of the community. The Open Source movement is working toward most of the same goals, but takes a more pragmatic approach to them. Followers of this movement prefer to base their arguments on the economic and technical merits of making source code freely available, rather than the moral and ethical principles that drive the Free Software Movement.
