Doesn't make much sense to me. This separation(indexer-provided/user-provided 
and don't forget app-provided) metadata is better handled on the ontology 
level to provide flexibility. Of course storage can handle user metadata in a 
different way like make sure not to corrupt or lose it because unlike file 
index it can't be rebuilt.
