A colleague pointed out to me this morning that the SPARQL 1.1 grammar
does not support solution modifiers (including GROUP BY / HAVING) with
ASK queries.
This means that you cannot use ASK to ask a boolean question involving
aggregates ("are there any countries that have more than 5,000
cities?"). (Well, you can do it using a subquery, but not directly.)
Is this purposeful?
thanks,
Lee
