Re: [dotNetRDF-develop] Access general SPARQL-endpoint

[Rob V. <rv...@do...>]

Hi Alexander

You can either use the SparqlRemoteEndpoint  
(VDS.RDF.Query.SparqlRemoteEndpoint) class which provides specific methods 
for making SELECT/ASK and CONSTRUCT/DESCRIBE queries and can connect to any 
SPARQL endpoint with the ability to specify the default & named graph URIs 
you want to use.

Or you can use the SparqlConnector (VDS.RDF.Storage.SparqlConnector) which 
has the same basic interface (IGenericIOManager) as the VirtuosoManager and 
gives you read-only storage access to an endpoint.  The disadvantage of 
this class is that it isn't as easy to specify default/named graph URIs if 
you need to (the advantage being that it implements the IGenericIOManager 
interface)

Take a look at 
http://dotnetrdf.org/content.asp?pageID=Querying%20with%20SPARQL for 
details on using the SparqlRemoteEndpoint class

If you have any further questions let me know

Subject: [dotNetRDF-develop] Access general SPARQL-endpoint 

Hello!

I need to access Virtuoso but not their ADO.NET provider (so 
VirtuosoManager doesn't work for me) but through SPARQL protocol 
(lod.openlinksw.com/sparql). What classes should I use?

Regards,
Alexander
