Ideally, a good document management system should manage revision cycles,
author info, etc. for an author, but absent the $100K solution it's nice
to figure a way to allow a single author (or a married one for that matter)
to add metadata directly into a document using vi.

Yes, XLink gives us this ability. I've also thought lately about auto-
mapping this information into a topic map, just as others have had similar
ideas using RDF. In the end I think the more difficult task is embedding,
so I tend toward the tough ones first, the rest follows.
