SPARQL Update over model
Hello,
I'm trying to make a SPARQL update query over a model, the problem is that
the query has to delete a triple belonging to a specific graph:
PREFIX dc: <http://purl.org/dc/elements/1.1/>
DELETE {
GRAPH <http://3cixty.com/cotedazur/test> {
<
http://data.linkedevents.org/event/51f5ecc8-55b4-3a1b-98de-55e4448ab7bf>
dc:identifier ?o .
}
} WHERE {
GRAPH <http://3cixty.com/cotedazur/test> {
<
http://data.linkedevents.org/event/51f5ecc8-55b4-3a1b-98de-55e4448ab7bf>
dc:identifier ?o .
}
}
which apparently has no effect when we proceed that way:
Model model = RDFDataMgr.loadModel("file.ttl");
UpdateAction.parseExecute(sparql_query, model);
I suppose it is normal as I never created the graph in the model.
Nevertheless when I do:
Model model = ModelFactory.createModelForGraph(new
SimpleGraphMaker().createGraph("http://3cixty.com/cotedazur/test"));
model.read("file.ttl");
UpdateAction.parseExecute(sparql_query, model);
It has no effect as well. Can someone guide me on how to do such thing
properly?
Thanks in advance.
Regards.

Ok I found the trick:
Dataset ds = DatasetFactory.create();
ds.addNamedModel("http://3cixty.com/cotedazur/test",
RDFDataMgr.loadModel("myfile")));
Thanks a lot for the hint!!

Re: SPARQL Update over model
Posted by Julien Plu <ju...@redaction-developpez.com>.
Sorry but I don't understand how to use the DatasetFactory to do what I'm
looking for, is there such method that takes two parameters, one is the
name of the graph and the other is the model?

Try starting with:
https://jena.apache.org/documentation/javadoc/arq/org/apache/jena/query/DatasetFactory.html
(I probably should have said that to begin with.)

Thanks! I will try to use

seems to be what I'm looking for.

A model holds exactly one graph. Perhaps you want to be using a dataset [1]?
