This issue has come up multiple times, but without much result. What specific features does Commons need to have? A list of this might be interesting, because their are very likely users who are willing to implement those kind of things, either as an extension, javascript hack or external service.

Let me say that I'm not a photo professional, but I know well that on image banks metadata is the king. Our support for metadata right now is a hack of MediaWiki templates that are very difficult to edit, and are not searchable. Then, there are professional standards like IPTC to add rich metadata to pictures. Work on that standards is already done, is professional and we should take a look to them instead of trying to reinvent the wheel. Tags ( a la flickr) are a mess as our categories are, it is very hard to keep them organized following the wiki model.
Of course, editing full IPTC can be difficult as is complex (having many fields to fill in). But a simple interface could have the most important fields to edit, and have an advanced editor for experienced users. This interface should allow the edition of IPTC registering changes an versions as we do with text (so you are able to compare each version of the metadata as you do now with text, that's the wiki concept).
Once we can provide images with rich metadata, a lot of tools can be developed to generate advanced searches.
There would be a way for commons to track all kinds of metadata, a way I (and others, IIRC) have proposed a long time ago: Store the values passed to each template on each page in a database table.
With an IPTC template on many image pages, and assuming that data is actually filled in, one could then search for, say, all images taken in Berlin on July 3, 2006. Or all images I took of flowers. Or... (you get the point).
Of course, this was dismissed at the time, because WikiData would take care of all of that. Which eventually lead to a tool by kolossos on the toolserver which tries to replicate this function. [1] shows all biographies on de.wikipedia of people who were born in London.
Of course, that functionlality should really come as a MediaWiki extension. The parser does generate the needed data anyway, it is merely a question of storing (and searching) it.
