I see the key value proposition is that is provides a semantically sound basis 
to combine data from different sources -- provided that the different sources 
use terms in consistent ways (i.e. satisfying the same semantic models).

The core if this, IMO, is the semantic entailment associated with RDF graph 
merges, per the "Merging Lemma" in 
http://www.w3.org/TR/2004/REC-rdf-mt-20040210/ (section 2 and appendix A).  (I 
just noticed this is omitted from the latest model theory - I assume it hasn't 
been invalidated by the changes.)

It turns out, per a poster by Patel-Schneider and Haves presented at ISWC 2013 
(http://iswc2013.semanticweb.org/content/posters/14) these core semantics are 
extremely weak.  IMO, that's a feature not a bug, if sufficient to allow graph 
merging without loss of corruption of meaning.
