Hi,
I am trying to adapt the DBpedia plugin to work with graph groups in
http://live.nl.dbpedia.org
Right now I have the "http://nl.dbpedia.org"; as a group graph that contains
the "http://live.nl.dbpedia.org"; and "http://static.nl.dbpedia.org";
The problem is that the description page is rendered using SQL from
RDF_QUAD limiting to specific gragh [1], the "http://nl.dbpedia.org"; which
does not exists in that table. resulting in empty html pages [2] but not
empty data pages [3].
Although I could adapt the queries for this case I would like to use the
same code for both static & live dbpedia's
Is it possible to generate a dynamic "IN" clause and depending on the
settings to fill it with 1 or more graphs?
I am not sure how to do this in VSP but I imagine it something like "...
AND G IN ( list of graphs)..." instead of G = _G
The second case would be to convert SQL to SPARQL but I am not sure on the
performance impact it would have
Best,
Dimitris
