I have no idea if Tracker uses just one huge file for everything or if
it can use one file per application/domain/whatever (and in any case
that's an implementation detail not terribly important for this debate
IMHO). My only point is that something like tracker-store is already
useful even if you don't ship a single filesystem miner with it. You
could even argue that in many cases it's better for the apps to feed
the data directly to tracker and cut the middleman of writing it into
the filesystem for miners to find it at a later point.

For that it'll be useful if an app had its own RDF onthology (a set of
classes and relationships) and use that to differentiate its data from
the rest of the database content.

That doesn't really help. A shared ontology is the best way to provide a shared understanding of what connects entities. Nepomuk does this.

However, there is talk of supporting quadruples which allows multiple data to be stored in the database but from different sources. For example, let's say you have an mp3 and store LastPlayed date, but you have 2 media players that can do that on the desktop, you would want to make sure your application data is not overwritten by the other application right...
