Can someone clarify what are the semantic/triple store features that I can access from a .NET client/API.

1) Upload data
a) Bulk or Batch load (guess no)
b) Using inserts (guess yes)

2) Query data
a) Using SEM_MATCH (?)
b) Using SPARQL (guess no)

3) Inferencing
a) Standard rulebases: RDFS, OWLPrime etc.
b) User created rulebases

thanks,
Ram
