Creative Commons licenses are attached to Web pages. But we also want our licenses to be useful for materials distributed in file formats around the Net. The protocol described here works for many filetypes.

If your software does not transparently support embedding CC license metadata (you should only have to select a license), do not attempt to do it yourself (it will be a frustrating experience).

The advantage of the verification link

Embedding this kind of "verification link" in MP3s, as opposed to merely the license metadata, is a measure of protection for artists against the incorrect or fraudulent labeling and sharing of their work.

Ravi circulates the photos among his schoolmates, whose photo-viewing software reads the copyright fields and takes them to the SNAP website, where they can see Ravi's whole catalog of photography and links to other SNAP services.
