[Sparql4j-devel] Integration of external RDF APIs via Factory

[Timo W. <tim...@pr...>]

Hello.

Concerning SELECT results access it would be possible to plug RDF apis 
into the driver via a factory interface.

We could provide a neutral SPARQL4J dependent minimal RDF API and in 
addition to this the possibility to plug external APIs into the driver.

RDF nodes (or any other objects returned by the factory) could be 
accessed via the umtyped accessors of the JDBC result set.

e.g.

interface NodeFactory{

  public Object createLiteral(String lex, String lang, String datatype);

  public Object createResource(String uri);

  public Object createResource(String ns, String local);

  public Object createBlankNode(String internalID);

}

The name of the implementation class could be given to the Driver via 
the property map.

Br,
Timo.
