Graham, do you mean your query that works like RDF with blank bits? I presume
it is easy to map between similar syntax types (squish and algae look the
same to me) but is it easy to map from a "holey-RDF graph query to a
SQL-style one?

(You might be right about it being early to standardise, but it might be
intersting to think about whether that is true and not assume it).

cheers
