The ontology files installed by nepomuk-core (master) would then get outdated by the nepomuk-core 4.10.2 release, even though my XDG path has been set to let nepomuk-core (master) take precedence over nepomuk-core (distro)

That's what I was asking about on IRC the other night.

I'll have another patch, that checks installed version of any ontology against the version set in the .ontology file.
Usually the mtime of this file was checked instead.

We just need to make sure, the version number there is always updated correctly than.
Because there is a second versions number in the .trig file, together with additional info like "is it upgrade able" etc.
But parsing this info might be more complicated.

What do you think?
