Hi folks
Discussing the examples in
http://ukwebfocus.wordpress.com/2010/02/19/response-to-my-linked-data-challenge/
which use facilities beyond SPARQL 1.0, I'd love to know if there are
any tentative 1.1 implementations out there, or any utilities that can
help classify a query to say how 'standard' it is, whether the
constructs it uses are already standard, proposed as standard, similar
to draft standards, etc.
Here (below) is an example query (which currently runs nicely on
DBpedia). How can we find out easily whether it is well-alligned with
the current 1.1 draft? Does anyone have an implemention or endpoint?
Am Cc:'ing Alejandra García Rojas Martínez who created the query I
guess by trial and error against DBpedia...
cheers,
Dan
