In many cases a good well prepared call for action is all that is needed. Explain, what needs to be changed and where.

There is a tutorial (although probably not a user-friendly one) at Multimedia/Media_Viewer/Template_compatibility.

The call for action can also be integrated right in the UI post launch, where MMV can say "Unable to show all information for this image. Please report this image to the community".

Not sure how we can tell that there is information that we can't display, unless we just show this for every image which does not have a compatible information template.

What is left after that, is probably not worth investing time in, until the time that we have true structured metadata.

Images that are uploaded to other places than Commons will not have structured metadata. (Not in the foreseeable future, at the very least.)

Also important, we need a good cross wiki meta tag for fair use. (and figure out what to do with those in MMV).

Non-free images usually have a license-like template (such as {{Non-free_fair_use}}), that can be marked up as a license template so it's displayed by MediaViewer.
