describing copyright in RDF

The CC schema lets you describe copyright licenses in RDF. Here's a summary of the included terms:

cc:license
A copyright license for the resource, a structured cc:License. If there are two cc:licenses, then the licensee gets to pick which to use.

Agents (people or things that do stuff) and Licenses, of course, can use the same structure to provide their names, dates, etc.

Licenses

Licenses are described by their characteristics, which come in three types:

Permissions (rights granted by the license)

Reproduction
the work may be reproduced
Distribution
the work (and, if authorized, derivative works) may be distributed, publicly displayed, and publicly performed
DerivativeWorks
derivative works may be created and reproduced

Prohibitions (things prohibited by the license)

CommercialUse
rights may be exercised for commercial purposes

Requirements (restrictions imposed by the license)

Notice
copyright and license notices must be kept intact
Attribution
credit must be given to copyright holder and/or author
ShareAlike
derivative works must be licensed under the same terms as the original work
SourceCode
source code (the preferred form for making modifications) must be provided for all derivative works

Note: these characteristics are advisory only. They are designed to describe the characteristics of a license; they are not themselves a license. For the specific implementation of each characteristic, as well as other details which may not be encoded in the RDF, you must consult the text of the actual license. A license should always be linked from these metadata terms.

More details are on the Creative Commons metadata project website.
