is SPARQL UPDATE supported in TDB

[Milorad Tosic]

Hi,

Does TDB support SPARQL UPDATE? 


I have a simple Java code that instantiates TDB like:
...
                Query query = QueryFactory.create(querystr);
                QueryExecution qe = QueryExecutionFactory.create(query, 
m_triplestore);
    
                ResultSet results = qe.execSelect();
                ResultSetFormatter.out(out, results, query);

...

Initially, TDB is empty.


For querystr = 

SELECT * WHERE { ?x ?p ?o }, 

I got expected result i.e. an empty set of triplets.

However, for querystr =
PREFIX eg: <http://example.org/ontology#>
INSERT DATA
{
  eg:dummySubject1 eg:dummyPredicate2 eg:dummyObject2.
}
TDB didn't recognize the "INSERT DATA" keyword, and reported:
com.hp.hpl.jena.query.QueryParseException: Encountered " <INSERT_DATA> "INSERT 
DATA "" at line 2, column 1.
Was expecting one of:
    "prefix" ...
    "select" ...
    "describe" ...
    "construct" ...
    "ask" ...


My configuration is like follows:

arq-2.8.7.jar
jena-2.6.4.jar
tdb.0.8.10.jar

Thanks,
Milorad
