But this isn't to take away from a fabulous achievement by the team
getting this fantastic new service up and running -- a service which
will presumably only get quicker and quicker as it gets more and more
optimised and more and more scaled up. So a very great thanks to all
concerned!
All best,
James.

FWIW, I'd be happy to turn WDQ into a
"redirect" that takes WDQ commands,
uses the WDQ-to-SPARQL translator, runs SPARQL, and returns the
results in
WDQ format. THis would be for backwards compatibility only. I hope people
will start using SPARQL instead of WDQ where possible, and I will add
SPARQL options to my tools where appropriate over time.
As it is, some queries (e.g. large result sets like "all humans without
image") do not work on SPARQL yet. I will try to keep WDQ running
until all
WDQ queries can run as SPARQL as well.
