Re: OPTIONAL with VALUES in Fuseki

I would add that a possible solution could be some mechanism for conditional binding, e.g., BIND ( IF ( ?surname != '', ?surname, UNBOUND ) AS ?mySurname ), but apparently there is nothing like that in SPARQL (apart from FILTER inside OPTIONAL). M On 26/02/2017 20:35, Zak Mc Kracken wrote: H

Re: OPTIONAL with VALUES in Fuseki

Hi Andy, thanks for your answer. I knew about UNDEF, but the fact is I don't have control over the data (as I said, I'm trying to fit this into TARQL, which takes a csv and adds a VALUE block to a CONSTRUCT template, to convert to RDF). I'll see what the authors of the tool say about the opti

Re: OPTIONAL with VALUES in Fuseki

Zak, Using ?surname in the OPTIONAL-BIND does do not what you want. You'll want the VALUES block before the OPTIONAL but even then the problem is that the OPTIONAL matches graph pattern (an empty one) so ?surname is not set in the OPTIONAL. Ideally, put UNDEF in the values. Andy PREFIX
