Yes.

CONSTRUCT WHERE { P } is a short form for

CONSTRUCT { P } WHERE { P }

(In fact, that is how it is executed.)

The restrictions on P used as a template apply.

"CONSTRUCT WHERE" is extract this subgraph where the subgraph 
description is restricted to what is allowed in a tenplate. 
Turtle+Variables.


[52]  TriplesTemplate  ::=
 TriplesSameSubject ( '.' TriplesTemplate? )?

Re: SPARQL Update over model

2017-02-16 Thread Julien Plu

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: Likely bug: short form for the CONSTRUCT query + GRAPH => syntax error

2017-02-16 Thread Andy Seaborne


Hi,

The result of a CONSTRUCT is an RDF graph and the template must be a 
"triples template"


[10]ConstructQuery::=
 'CONSTRUCT' ... 'WHERE' '{' TriplesTemplate? '}'  ...

and

[52]TriplesTemplate   ::=
 TriplesSameSubject ( '.' TriplesTemplate? )?

No GRAPH.

Jena accepts  CONSTRUCT WHERE { GRAPH  }
in extended mode (Syntax.syntaxARQ) and returns a Dataset.

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]?

SPARQL Update over model

2017-02-16 Thread Julien Plu

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:
DELETE {
GRAPH  {
<
http://data.linkedevents.org/event/51f5ecc8-55b4-3a1b-98de-55e4448ab7bf>
dc:identifier ?o .
}
} WHERE {
GRAPH  {
<
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.

Likely bug: short form for the CONSTRUCT query + GRAPH => syntax error

2017-02-16 Thread Jean-Marc Vanel

Hi

I tested with 3.2.0.

The short form for the CONSTRUCT query
https://www.w3.org/TR/sparql11-query/#constructWhere
works, at least syntactically ( I have nothing in the default graph in my
TDB ) :
CONSTRUCT WHERE
 { ?X ?P ?O . }
 LIMIT 10

But adding GRAPH pattern gives a synyax error:
CONSTRUCT WHERE  {
GRAPH ?G {
?X ?P ?O .
}
} LIMIT 10

Which does not occur e.g. with Virtuoso.

org.apache.jena.query.QueryParseException: Encountered " "graph" "GRAPH ""
at line 2, column 1.
Was expecting one of:
 ...

 ...
 ...

You need to do a federated query. See the SPARQL 1.1 Query spec.

Good suggestions.




Hi,

I have a question about striving the local name out of the URI.

SO for example,

the URI I print it out looks like the following:
http://example.com/resource/authors/%28Zhou%29_Bryan_Bai


if I apply:

String localName = resource.getLocalName();

the value of localName is : _Bryan_Bai .
How do I get the value as Zhou_Bryan_Bai


A local name follows the rules for XML qnames.

They can not start with a digit.

They can not contain %

so the longest is "_Bryan_Bai"

Thanks in Advance!

 In general, you cannot remove inferred statements - those are given by
 data + rules.

 Indeed, you can remove statements on a materialized inferred model, but
 implicitly the class assertion does still exist.
