This formulation of W3C's notice and license became active on December 31 2002. This version removes the copyright
ownership notice such that this license can be used with materials other than those owned by the W3C, reflects that ERCIM
is now a host of the W3C, includes references to this specific dated version of the license, and removes the ambiguous
grant of "use". Otherwise, this version is the same as the previous version and is written so as to preserve the Free
Software Foundation's assessment of GPL compatibility and OSI's certification under the Open Source Definition. Please see our
Copyright FAQ for common questions about using materials from our site, including specific terms and conditions for packages
like libwww, Amaya, and Jigsaw. Other questions about this notice can be directed to site-policy@w3.org.
