we have for the last 5 years been doing the equivalent of developing
relational databases without SQL. The query language, SPARQL, now in the
final stages of standardization, is for many people a key to the usability

That is *not* what Tim said about SQL. There is nothing wrong with
designing a YAQL (Yet Another Query Language), but it was hopelessly
naive to think that they could replace the language that runs the world
economy and the overwhelming majority of commercial web sites.
The Semantic Web (and RDF heavy) narrative typically misses the
opportunity to present SPARQL as being all about unveiling the
missing intensional dimension (so to speak) or relational database
SPARQL (relational property/predicate graphs) and SQL (relational
tables) compliment one another in powerful ways. Sadly, the tendency
is to think of SPARQL as a "rip and replace" alternative for SQL
which drives a majority of the worlds database driven solutions.
