Allow to pass query and model to SPARQLModelAdapter.query

[b1rger]

currently I have to instantiate a SPARQLModelAdapter for every query I want to run. But the target is always the same. It would be great if I could have one instantiated SPARQLModelAdapter and then pass the query and the model to the query method

The association of a SPARQLModelAdapter instance with each route is a deliberate design choice, as this suggests a modular and flexible approach to defining endpoints, allowing the modification and extension of individual routes without affecting the rest of the API and also enabling a single RDFProxy-based backend to potentially connect with multiple SPARQL endpoints.

Please consider using partial application or other means of wrapping a SPARQLModelAdapter object, e.g.

PFPAdapter = functools.partial(SPARQLModelAdapter, target="your.endpoint")

adapter = PFPAdapter(query=query, model=model)
adapter.query()
