I may not be understanding your question properly, but RDF makes no real 
distinction between "information" and "meta-information".  As you've 
noted, RDF allows the description of resources (named by URIs).  That's 
it.  RDF per se doesn't care what those resources "are", i.e., whether 
they're data, metadata, real things, imaginary things, etc.  If you want 
to make such distinctions for your own purposes, you can use (or make 
up) an RDF vocabulary that reflects the distinctions you think are 
important, using specialized classes and predicates (as RDF Schema and 
OWL, for example, do).
