In the common case, Media Viewer provides more prominent and
appropriate attribution and license information than the File: page.
The author name, license, license URL, and source URL are all
immediately accessible below the image, whereas on the File: page
there are sometimes screenfuls of metadata between the image and this
crucial information.

This is actually a pretty remarkable accomplishment given that this
information comes from a huge number of different templates that vary
across wikis. Media Viewer makes use of standardized CSS classes to
extract metadata, and the team has actively worked with the community
to broaden their use:

Ultimately we'll want to use proper structured data for this, but
these changes lay the groundwork, and there's already an API (used by
Media Viewer but open to anyone) that exposes this information.

Where no license is detected, Media Viewer still falls back to a "View
license" link. The more problematic cases are where actual errors
occur and important information is not extracted, and there will
certainly inevitably be some cases where this happens, but this can
only be worked on over time. The expectation that an unbounded problem
like this is completely solved prior to deployment of a feature is
unreasonable -- it's similar to TemplateData, in that the positive
feedback loop into Media Viewer should actually help encourage more
and consistent use of machine-readable data.

Can you give a specific, current example?

It takes exactly one click using the "View original file" button.

Thanks,
