John, (02)
RDF is just a framework for constructing entity relationship graphs
endowed with machine-comprehensible entity relationship semantics. Did
the Semantic Web folks pitched this whole vision poorly? Of course they did. (03)
SPARQL is just a declarative query language that's totally superior to
SQL for intensional interaction with data. Basically, we are looking at
a contemporary variant of Quel [1] that incorporates many of Codd's
concerns with SQL [2]. (04)
Linked Data (which you don't mention above, but is a source of the
latest Semantic Web's poor marketing practices) [3] is the piece that
enables Web-scale super keys via de-referencable URIs that resolve to
URI referent descriptors (or description documents) that bear RDF based
content in the form of entity relationship model based description graphs. (05)
Interoperability and heterogeneity is baked into the Semantic Web stack,
as exemplified by its Linked Data underpinnings. IMHO. The only thing
wrong with all of this is horrible marketing driven by misguided
zealotry around the letters "R-D-F" . (06)
A Semantic Web of RDF/XML is as dead as XML itself. (07)
A Semantically enhanced Web of Linked Data loosely with ontologies is
growing in leaps and bounds by the minute :-) (08)
