If solid treats the device as removable then Nepomuk will convert all
the URLs into filex:/ ones to allow matching properly when remounting at
another mount point.

The whole filex:/ situation is a bit weird. I am not sure yet on how to
solve it. Currently you can ask the removablestorageservice to translate
the filex:/ URL into a local file:/ URL. It has a DBus method for that
which is also used in Nepomuk::Resource.
That said it could make sense to add functionality to Nepomuk::Resource
to expose the local path of a file.

I think we need to discuss the whole issue with removable media again.
Should the files be indexed? Should the metadata be removed when
unmounting? But then we have the same problem again: the fat partition
you mention is not removable as far as the user is concerned. How to
detect that?
