Can GraphEngine support RDF ?

Question

Does GraphEngine support RDF and SPARQL, as described in the paper:A Distributed Graph Engine for Web Scale RDF Data : https://www.graphengine.io/downloads/papers/Trinity.RDF.pdf

If not, could it be implemented on top of the engine, or is it in the roadmap?

Answer 1

Please take a look at our sample code for hosting Freebase:

https://github.com/Microsoft/GraphEngine/tree/master/samples/freebase-likq

The implementation is in src/LIKQ, and samples/freebase-likq provides an example of integrating an index service, multi-typed entity adapters with the LIKQ module.

The freebase dataset is imported as a Trinity image via samples/GraphEngine.DataImporter (currently in the experimental branch). It scans the data twice, first round to decide the data types for the entities and generates TSL storage layout schema, and the second round for the actual import work.
