Re: [sparql-wrapper-devel] Query bad formed

[Carlos T. <car...@fu...>]

Dear Mariano,

Maybe the problem is the declaration of the prefixes (i can't find it in
the sent snippet).

And you should check the WHERE clause. It seems that something is broken.

As a tip, you can check the SPARQL query in a web-based SPARQL endpoint
(such as [1]), that maybe returns more information about the problem.

Best regards,

Carlos Tejo
