After a private interchange with David, I have come to realize that he does 
have a point, but perhaps not the one that is explicitly stated in his message.

There are a number of places where "interpretation" is used in Semantics 
without qualification.  In most of these cases, "simple interpretation" is 
what is meant, and I think that making this change, although somewhat pedantic 
(because there is only one kind of interpretation that could be meant in 
almost all these cases), would be beneficial.   I'll send out a message with 
what I think are the needed changes.

This definition of simple interpretation appears, slightly modified, in the 2013 RDF 1.1 Semantics document in Section 4. While the section titles and numbers are changed, and the introductory material has been removed, the normative definitions in the RDF 1.1 document are very similar to, and stated in the same order as, those in the 2004 RDF document. Neither document defines a general notion of interpretation.

The WG received some strong feedback to the effect that the 2004 documents were too long and 'heavy', motivating the editorial purging of extraneous text.  For these reasons, we do not intend to incorporate such material into the normative RDF 1.1 Semantics.

AFAICT, the general notion of an "interpretation" is nowhere defined.  Later in the document, specific kinds of interpretations are defined, such as Simple Interpretations, RDF Interpretations and RDFS Interpretations.  But AFAICT a definition of the general notion of an interpretation is completely absent.
