Hi,
Another question: I'm loading a model from an RDF/XML file that contains
blank nodes identified by rdf:nodeID="A...". On loading the file into a
dbmodel I notice the blank nodes are being duplicated: for each set of
triples using the nodeID A... I get a second set of triples using bNode...
Eg. if my file contains
<rdf:Description rdf:about="http://www.chi.knaw.nl/editor/annotationset">
<j.1:hasAnnotationTypes rdf:nodeID="A3"/>
...
</rdf:Description>
<rdf:Description rdf:nodeID="A3">
<rdf:type rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq"/>
<rdf:_1 rdf:resource="..."/>
</rdf:Description>
I would expect there to be a triple:
Resource("http://www.chi.knaw.nl/editor/annotationset")
Resource("http://www.chi.knaw.nl/editor/hasAnnotationTypes") bNode("A3")
but there is also:
Resource("http://www.chi.knaw.nl/editor/annotationset")
Resource("http://www.chi.knaw.nl/editor/hasAnnotationTypes") bNode("bNode4")
Similarly, I would expect
bNode("A3") Resource("http://www.w3.org/1999/02/22-rdf-syntax-ns#type")
Resource("http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq")
but there is also:
bNode("bNode4")
Resource("http://www.w3.org/1999/02/22-rdf-syntax-ns#type")
Resource("http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq")
etc.
This makes my models larger than they need to be, and plays havoc with
my queries. Anyone has a suggestion on why it should occur, and on how
to avoid it?
Thanks again,
Peter
