That depends a bit.

Tracker technically uses Nepomuk + extensions to fill the gaps we need 
filling, so yes it does use the standard, but not the library or source 
works from the KDE folks.

From what I've heard lately, KDE is moving away from Nepomuk, so it was 
common but perhaps not now?

As for libnepomuk*, I have no idea, but we're not using it.

Well, tracker is an RDF store. Perhaps you mean "using the Tracker RDF 
store" ?

Try away, but it's unclear to me what you think you would be breaking 
here. If you have indexed content in Tracker and you change the 
ontologies installed in to /usr/share/tracker/ontologies/ then the next 
restart of tracker-store might spit errors out at you ;)

In the worst case, you can just tracker-control -r (to reindex) after 
fixing your changes. There are also ontology validation scripts/tools in 
the Tracker code base (see utils/ontology/).

I've not looked into it personally.

What's your aim here, may I ask?
