Hi,
To begin, thanks for building d2rq server, it's a great and useful product.
I though encountered a little problem.
I use D2RQ for "rdfise" a mysql based thesaurus into a skos model.
So I would like to define a conceptScheme in top of the rdf thesaurus.
Something like :
<skos:ConceptScheme rdf:about="http:/example.com/thesaurus">
<dc:title>The SWAD-Europe Example Thesaurus</dc:title>
<dc:description>An example thesaurus to illustrate the use of
the
SKOS-Core schema.</dc:description>
<dc:creator>A J Miles</dc:creator>
</skos:ConceptScheme>
(example take from [1])
As I read here http://www4.wiwiss.fu-berlin.de/bizer/D2RQ/spec:
"A d2rq:ClassMap usually produces many resources. Sometimes it is
desirable to have a class map that only produces a single resource with
fixed, static identity. In that case, one can use the d2rq:constantValue
property to name the single instance."
I think that is what I need.
So I define
map:Throot a d2rq:ClassMap;
d2rq:dataStorage map:database;
d2rq:class skos:ConceptScheme;
(1)
d2rq:constantValue "http://example.com/thesaurus/0.1/";;
.
But I have the error :
"d2rq:ClassMap map:Throot needs a column/pattern/bNodeID specification (E0)"
I try to add in (1) to the clause :
d2rq:uriPattern "http://gasoil.edf.fr/thesaurus/0.1/";;
But it's throw the error :
d2rq:ClassMap map:Throot can't have both d2rq:uriPattern and
d2rq:constantValue (E0
And when add in (1) the clause :
d2rq:bNodeIdColumns "entree.cle";
Take the same class of error
d2rq:ClassMap map:Throot can't have both d2rq:bNodeIdColumns and
d2rq:constantValue
Any input will be much appreciated.
Thanks
