There is a saying that only God knows the true name of something. :-)

My experience with prefLabels is that they need to be assigned to a context in a mesh-up environment. Datasets that don't do this a priori need to be mapped to a context before being merged. In an RDF environment, this is clunky but possible by adding a skos:inScheme property when labeling concepts. 

If you want to assign prefLabels to non-conceptual things, I've found foaf:focus useful. That's what we do in VIAF. These extra levels of abstraction work, but they aren't easily understood.
