There is an enormous body of open photographs contributed by a myriad of
libraries and museums to flickr.  Is anyone aware of any efforts to
associate machine tags with these photos, for example to georeference with
geonames machine tags, tag people with VIAF ids, or categorize with LCSH
ids?  A quick Google search turns up nothing.  There's a little bit of this
going on with Pleiades ids for ancient geography (
http://www.flickr.com/photos/tags/pleiades%3A*/), but there's enormous
potential in library-produced images.

I think it would be incredibly powerful to aggregate images of manuscripts
created by Thomas Jefferson (VIAF id: 41866059) across institutions that
have digitized and uploaded them to flickr.
