It would be great if it’s possible to paste the RDF into a textarea (instead of having to select a file). At best it would support all these ways how to specify the RDF to be queried:
- paste the RDF
- select a local RDF file
- enter a URL to an online RDF file
- load the RDF as specified in the SPARQL query (via
FROM, or whatever mechanisms SPARQL supports)
The more RDF serializations formats are supported, the better. It should at least support Turtle (but I don’t require this, as I could use a converter if a recommended solution is worth it).
I don’t have any restrictions regarding the result format.
A solution must
- be FLOSS,
- run natively on GNU/Linux, and
- work offline.
