There's a sparqlEndpoint property in voiD, that currently has  
void:Dataset as a range [1], but I guess they could extend it to make  
it more generic.
Also, SIOC (in the Services module [2]) has a has_service property  
that links anything to a related service. This service can then be  
defined as being a SPARQL endpoint using:

<some-resource> siocs:has_service [
   siocs:service_protocol <http://www.w3.org/TR/rdf-sparql-protocol/> ;
   siocs:service_endpoint <http://sparql.example.org/endpoint>
] .

Hope that helps,

Alex.
