I have the following problem with editing ontology data. i can query the data at wikidata per sparql, but they only return json files. These files only contain the s p o format.

But i want to extend this data with my own stuff (using owl from wikidata). To do so I have to import them into some framework.

How can I do this and which tools do I need?

one example query:

SELECT ?subclass ?entity ?predicate WHERE {
  ?subclass (wdt:P279*) wd:Q2095.
  { ?entity ?predicate ?subclass. }
  UNION
  { ?subclass ?predicate ?entity. }
}

what kind of query do you send? If you want RDF data, you have to use a SPARQL `CONSTRUCT` query instead of `SELECT` – UninformedUser May 29 '20 at 08:05

as I said, use a `CONSTRUCT` query instead and you will get proper RDF which you can use in whatever tool you use – UninformedUser May 29 '20 at 08:45
