Actually a bug in CommonsMetadata - it's returning "LicenseUrl" instead of "License" on Commons images. We either need to translate LicenseUrls into licenses, or use the existing solution we have based on categories...maybe CommonsMetadata can't see hidden categories on a remote site? Investigate.

Assigning Gergo.

CommonsMetadata is intended to run on the central repository, but in our test setup it actually runs on the frontend wiki. It still kind of works, but some things are not accessible for a remote file, and remote categories are one of them. So License (which is based on categories) is not set, only LicenseUrl (which is based on the description page).

So wait.

Will this work once the central repo has CMD on it? Should I try to handle LicenseUrl too?

OK, we now fall back to the file page in _all_ cases. Try the new patch out for size. I'll close this bug since it never actually hit master.

Reopening this bug, because it is still happening on beta for all the photos I uploaded and featured on this page (Hong Kong, Aquarium, Kerala beach, Wikimedia team):

http://en.wikipedia.beta.wmflabs.org/wiki/Lightbox_demo

All these photos should display a 'CC-BY-SA-3.0' label in light box view, but are saying 'License info' instead.

Unfortunately beta sites use the real Commons, not Commons beta.
So this is more of a bug in our test setup than in MediaViewer/CommonsMetadata.

I can reproduce this problem on MediaWiki.org as well, which I don't believe is Beta.

None of the CC images I posted on this MW.org are showing the correct CC-BY-SA label: (aquarium, nautilus, Kerala beach)

To be clear, I and other user expect the 'Licensing information' label to be replaced by 'CC-BY-SA-3.0' or whatever license we put in when we uploaded a file, as specified here:

This is an important request, which is going to be echoed over and over again by other users until we fulfill it.

Apparently Commons is a ForeignDBViaLBRepo, not a ForeignAPIRepo, and CommonsMetadata cannot handle that. This will be complicated...
