I have been working on some blank node mappings for the sp2 database. My
mappings are below. As best I can tell d2r seems to be ignoring the
table.column I specified for the relevant d2rq:bNodeIdColumns property. The
values for the Person.stringid column are values such as Paul_Edroes.
When I run, SELECT ?resourceid WHERE { ?resourceid a <
http://xmlns.com/foaf/0.1/Person> } limit 10, to test the below mapping, I
am getting results back in that look like
_:b0, _:b1, etc. Based on the mapping, I was expecting the blank nodes to
look something like _:Paul_Edroes, etc.
Is the column specified in the d2rq:bNodeIdColumns used to create the blank
nodes? If so, is there something incorrect with my mapping that is causing
my blank nodes to be formed incorrectly?
Thanks.
*Mapping:*
:Person_BlankNode_Map
a d2rq:ClassMap ;
d2rq:bNodeIdColumns "Person.stringid" ;
d2rq:class foaf:Person ;
d2rq:dataStorage :SP2_Database ;
.
