Fascinating stuff, Jonas
This sounds somewhat similar to the image attribution service developed as part 
of the Xpert project here at Nottingham:
I can put you in touch with the developer if this is of interest to you.

Subject: [GMG-Devel] Metadata in MediaGoblin


I'm a previous employee of Creative Commons (where I worked at the same time as 
cwebber) and since March this year I'm working with the Shuttleworth Foundation 
on the concept of embedded metadata for digital works. Essentially trying to 
bring order to how people embed license information in EXIF tags and similar 

You can watch our introductory video here:

(yes, it should probably be Mediagoblin-hosted instead :-)

We would like to build a prototype around this with Mediagoblin. We've hacked 
Inkscape to have somewhat better support and UI for license metadata, and we'll 
be building a plugin to Firefox that places license metadata on the clip board 
when someone copies an image from a web page, something that can then be picked 
up by Inkscape.

What we'd love to do is to create a "full cycle re-use" scenario, involving 
Mediagoblin, Firefox and Inkscape. The story goes something like this:

1. An svg is uploaded to a Mediagoblin instance.
2. A user uses Firefox (with an add-on to copy metadata) to browse the 
Mediagoblin instance 3. The user selects one or more illustrations that the 
user wants to re-use or re-purpose 4. The user uses the new function "copy 
Image with metadata" (pending native support in the "copy Image" code) in 
Firefox and paste in Inkscape to copy one or more illustrations.
5. The user makes modifications to the illustrations, optionally changing the 
metadata 6. The user uploads the finished work to Mediagoblin as a new 

What we want should happen:

When the original illustrator uploads the illustration, Mediagoblin checks and 
displays the correct licensing and attribution information according to the 
metadata embedded in the illustration.

This metadata is retained through copy/paste in Firefox and when the user 
uploads a changed illustration, Mediagoblin attributes both creators correctly 
and gives accurate licensing information in both text and embedded RDFa as well 
as making a link to the original image.

Please note that this is not meant to be a finished product! We want to create 
this with Mediagoblin to show what could be done if support was in the tools we 

I'll be digging into Mediagoblin within the next couple of weeks to get a 
better understanding for where in Mediagoblin such support should go and how 
it's best implemented. Any thoughts on this in the mean time is obviously well 
appreciated :-)
