That is the ultimate goal. Technically is is perfectly possible. You can toy 
around with that using the PIMOShell in playground/base/nepomuk-kde. It 
allows to create any type of resource and even new classes and properties. 
You can then of course also tag these new resources.
For Amarok the ultimate goal is also to use abstract concepts such as Artist 
and Album decoupled from the actual files. Files will then "only" be 
incarnations of the abstract concept track.
But that will take some time. Would you be interested in writing a little 
example tool that tries to create these abstract resources from the id3 
information available? It could even contact services such as last.fm to 
enrich the data.

Cheers,
Sebastian
