It doesn't, no.  F-Spot predates Leaftag by several years.

SemWeb is an RDF library.  Tags are stored either in F-Spot's internal
sqlite database or as a part of XMP metadata in the image itself.

There's no API for it, no.

You've mentioned two apps which predate any tagging or other metadata
system in GNOME.  F-Spot uses a standard image metadata format when
appropriate, and Nautilus uses a straightforward XML format that has
been around for at least 6 years.  I would hardly call this a mess.

Applications do need to become richer, but Tracker isn't a silver bullet
for this.

But you're not offering to separate them.  So what's the difference,
really?
