Description
Some RDF triple stores offer a Linked Data Fragments endpoint. This is a query interface which is much simpler than SPARQL and is therefore often faster and more reliable (since it is cheaper for the service). Importantly, it supports paging, which lets a client download large sets of results without running into timeouts.
Proposed solution
It would be nice if OpenRefine supported importing from a LDF endpoint, similarly to how SQL databases are supported.
Alternatives considered
This is similar to the request for a SPARQL importer, OpenRefine/OpenRefine#1212 (because a lot of services offer both endpoints).

Research direction
Start by reviewing how OpenRefine supports importing from SQL databases and compare that with the Linked Data Fragments endpoint described here. The related SPARQL importer request, OpenRefine/OpenRefine#1212, may clarify expected integration. Done should include a working importer that can page through large LDF result sets reliably.
