Connect to a BrightstarDB triplestore and query it by using dotnetRDF

[Iván Palomares]

Hi,

I'm completely new to BrighstarDB but we are considering its use. I'd like to ask whether it could be possible to connect to RDF data triplestores stored in BrightstarDB from

a software based on the dotnetRDF set of libraries. From what I have seen in the "connections" documentation page, it seems like from BrighstarDB there exists a connection type

to connect from there to dotnetRDF, but I'm not sure about the other way round, which is what I would be interested in??

thanks in advance

kind regards,

Iván

Hi Ivan,

BrightstarDB does implement a standard SPARQL query and update endpoint for its stores [1], so if you run it as a server you can use DotNetRDF to access it through an appropriate storage provider [2]. 

To use DNR to access an embedded BrightstarDB you would need to wrap our IBrightstarService interface with and implementation of the appropriate DNR interfaces (probably INativelyQueryableStore at a minimum).

The main downside to this would be that you won't have access to any of the non-standard features of BrightstarDB (such as querying at commit points, or our more extensive transactional update operation). Of course, that may not be an issue for you if you are looking to create a layer for portability between the different stores that DNR supports.

BTW: can I ask you to please send any future questions to our Codeplex discussion forum [3] rather than to this group. 

Cheers

Kal
