Hi, over the time the questions like "how do I determine
programmatically the license of this image?" or "who is the author of
that video? no, uploader's username is not enough" are asked
quite regularly, and probably now it's time to fix this.
Please take a look here:
https://www.mediawiki.org/wiki/Requests_for_comment/Image_information
On that page, I'm trying to collect the requirements for extension
that would address these problems, as well as the ways of
implementation. If all goes well, I'd like to start coding in 1-2
weeks.
