Hi,
Is it possible to create an rdf attribute as a manipulation of 1 or more
columns from a table or does this have to be done in a sql view prior to
the rdf view? I attempted to perform a concat like the one below but got
the error - SQ074: Line 46: SP031: SPARQL compiler: Table alias name is
not specified for column concat.
Hi,
Yes, I believe it should be possible to use just about any virtuoso PL
function assuming it's been promoted to be visible from sparql and the RDF
meta-schema environment.
http://virtuoso.openlinksw.com/Whitepapers/html/rdf_views/virtuoso_rdf_views_example.html
has hints/example of how to do it - see the sections `Creating IRIs From
Primary Keys /IRI Classes' and Listings 3 and 4.
HTH,
