    Dear Benjamin,

SPARQL is not a feasible option for me as I need support for read/write operations.
However, I am interested to know if ActiveRDF can convert a Redland store into a SPARQL-endpoint.


A couple of days back I have started my exploration for the Oracle 11g support for RDF/OWL.
From my past experience, Oracle Call Interface, an API for C language, appears to be a good possibility.

I will get back with details, since my exploration has just begun.


Thanks.

With regards,
Harshal

Do you know how Oracle 11g can be accessed programmatically? How



could e.g. a Java or C programm access RDF triples from Orcale?

very true, I also have big trust that Oracle will deliever in those
areas.

You could either just access Orcale via SPARQL, as I am sure that
they support that. Usually, when creating a triple store it is
possible to specify if the store should incorporate reasoning. If
yes, then using SPARQL not only gets you the "real" triples but also

the inferred ones.

As for "native" access it would be necessary to know what kind of
APIs Orcale 11g RDF stores support.

There currently are no plans of which I am aware of. But if we know
how the Orcale 11g APIs then we can talk about further actions.

If you have the means to find that out, it would be much apreciated.


cheers, Benjamin.

By this, you probably mean the possibility of using
ActiveRDF to  
provide a SPARQL endpoint so that other services can re-use
your data.

There is no direct support for providing SPARQL endpoints in
 
ActiveRDF and I do not know of anybody who has implemented
this  
already with ActiveRDF.

But if you take a look at the way in which SPARQL queries
are send  
over HTTP, I think you can figure out how to set the Ruby on
Rails  
routes, so that the parameters of the query arrive at a self
written  
controller object, which constructs the query and and
returns the  
triples.

Keep in mind that ActiveRDF only supports a subset of the
SPARQL  
standard.

Taking a look at the 2 files of the SPARQL adapter will
probably also  
help with that.

Thank you, and I am looking forward to that.

cheers, Benjamin.
