I checked the link to the embedded info but couldn't find anything about embedding the info into the jpeg data. Is there a way to piggyback it into the EXIF data?

I think the idea is to put it in the EXIF data. Probably more info on the mailing list. Let me try to find out.

It's one of the challenges:

This search reveals a few mailing list posts with "exif":

In order to integrate the image and its description more closely, this document discusses some ideas such as how to extract Exif data, how to embed RDF in an image file, etc.

In all, not much specific to creative commons, but the path seems clear.

Thanks! I'll dig into it. I'm trying to use my photoblog as my CC testbed to see if anyone uses the stuff I post for consumption so any tricks that I run across I'm willing to give a go.

For SVG, inkscape supports embedding of RDF inside the
images. After all it is a question of namespaces, and
SVG was designed to be used with namespaces.

This is used by the openclipart.org people to state the
public domain status of their contributions. The information is lost when exported as png, though.
