XMP (Extensible Metadata Platform) facilitates embedding metadata in files using a subset of RDF. Most notably XMP supports embedding metadata in PDF and many image formats, though it is designed to support nearly any file type.

Creative Commons is recommending XMP as the preferred format for embedded metadata, given its support for numerous file formats and the balkanized state of embedded metadata standards. Others are coming to a similar conclusion; Microsoft has announced support for XMP in Vista applications and Jon Udell notes "There’s also good support in .NET Framework 3.0 for reading and writing XMP metadata." Note that even when embedded with XMP metadata, Creative Commons recommends a licensed document include a visible copyright notice; format-specific recommendations for visible notices are available.

The Creative Commons licensing process offers a XMP template which may be used to mark files within XMP-supporting Adobe applications (step-by-step how-to document).

Specifying License Information

XMP defines a rights management schema (see section 4.2.5). Creative Commons sets the following properties (example values):

We also define a Creative Commons schema http://creativecommons.org/ns# whose common prefix is cc.

It currently has the following property:

  • license — The license URL; for example, http://creativecommons.org/licenses/by-sa/2.0/.
  • morePermissions — A URL where additional permissions (commercial licensing, etc) are available.
  • attributionURL — The URL to use when attributing this work.
  • attributionName — The creator's preferred name to use when attributing this work.
