Hi Kunal, I donĀ¹t believe such specific document exists. The key to being able to query any form for RDF data is for this to be loaded into Virtuoso Quad Store, and their are various white papers and presentations on how this can be done at: http://virtuoso.openlinksw.com/Whitepapers The key

2008-02-07 Thread Ivan Mikhailov
Pierre, In order to access to SQL data via SPARQL you should create RDF Views first, then query mapped data as if they're usual RDF quads. There's no other way. Probably, we will never add an ability of calling SQL from SPARQL because that will cause problems similar to inlining of assembler fragm
