Linked Data Fragments importer

[wetneb]

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).

I am transferring this issue to the SPARQL extension since it would be weird not to support SPARQL but to support LDF in the core tool. Intuitively both features would appeal to a similar user base so it would make sense to have both in the same extension.
