For those of you interested in the metadata production and use in web 
technologies:

Creative Commons will hold its second technology summit on December 12, 
2008, in Cambridge, MA. The summit will focus on the application of 
Semantic Web technologies to Creative Commons', Science Commons' and 
ccLearn's missions. Topics covered will include ccREL/RDFa, the 
Neurocommons project and an update on the Universal Education Search 
(metadata-enhanced search) project.

"The Technology Summits are about connecting the larger developer and 
technical community that’s sprung up around Creative Commons licenses 
and technology, so we want to provide a venue where people doing 
interesting work can share it." - Nathan Yergler, CTO

Creative Commons is a non profit organization that builds tools that 
help realize the full potential of the commons in the age of digital 
networks. Launched at the end of 2002, Creative Commons licenses have 
set the standard for sharing cultural works (i.e., "content", "media", 
etc.), following in the footsteps of free and open source software. Over 
the past five years we have also actively developed and contributed to 
technologies that complement its public licenses, with the aim of using 
software to enhance the discoverability and practical [re]usability of 
content -- to help users manage content, as opposed to software designed 
to help content manage users (i.e., DRM). In 2006 Creative Commons 
launched Science Commons, a project applying similar principles to 
science and research. ccLearn was launched in 2007 to help minimize 
barriers to sharing and reuse of educational materials.
