{{Infobox|
'''Creative Commons Rights Expression Language (ccREL)''' is a specification describing how license information may be described using RDF and how license information may be attached to works.
|}}

ccREL is described in ''[[Media:Ccrel-1.0.pdf|ccREL: The Creative Commons Rights Expression Language]]'' (pdf), published March 3, 2008.  An overview of the vocabulary is available with [http://creativecommons.org/ns# the namespace description].

ccREL metadata, as encoded using [[RDFa]] or [[XMP]], may be [[Marking Works Technical|embedded]] in a variety of [[:Category:Filetype|filetypes]].  Additional confidence may be added to embedded metadata through the use of [[WebStatement|web statement]].

We have also begun to explore extending ccREL for use by digital copyright registries.  See [[CC Network Development]]'s [http://code.creativecommons.org/doc/commoner/metadata.html metadata documentation].

'''[https://opensource.creativecommons.org/ccrel-guide/ ccREL 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.
