Yes, higher-order is incorrect terminology.  I am a bit confused about
calling it a meta-language, though.  It depends on whether RDF is a
'language' or not.  Agreed certain RDF 'vocabularies' can be thought of as
languages, so in that sense it would hold true.

Though presumably I could more generally call it "meta-metadata" - the first
layer of statements represent data about data (metadata) - the next layer is
considered to be data about metadata (meta-metadata), ad nauseam.
