CC REL

CC REL is described in CC REL: The Creative Commons Rights Expression Language (pdf), published March 3, 2008. An overview of the vocabulary is available with the namespace description.

CC REL metadata, as encoded using RDFa or XMP, may be embedded in a variety of filetypes. Additional confidence may be added to embedded metadata through the use of web statement.

We have also begun to explore extending CC REL for use by digital copyright registries. See CC Network Development's metadata documentation.

CC REL by Example provides examples of many web deployment scenarios with thorough explanations and is the best place to start if you want a HOWTO or to understand through examples which you can copy and experiment with.
