[Rdfapi-php-interest] Duplicated bnode's on loading model?

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
