使用SimpleTcProvider的SPARQL查询

Question

I'm new to Jena, Clerezza, and OSGI so hopefully you'll forgive my ignorance... I'm trying to use Apache Stanbol to make a general enhancement engine that takes as a string parameter a SPARQL query and then works on the enhancements produced by the enhancement chain so far. I use a JenaSparqlEngine and a SimpleTcProvider to create a TcManager which can then execute the sparql queries as strings on the metadata of the content item. That works fine for read only queries, but when I try to use update queries I get parser exceptions. So I'm guessing I have to use (Jena) UpdateAction to perform update operations. Can I still use the SimpleTcProvider? Should I use Fuseki? If you have any examples that would be very much appreciated!

Found it. It works with SingleTdbDatasetTcProvider.
