Handle 1..N queries for converter. #59

Closed zwelz3 closed 3 years ago

zwelz3 commented 3 years ago

Monolithic queries are difficult to define, challenging to maintain, and in some cases less performant than multiple separate queries.

This ticket investigates a way to allow for N number of queries of each type for the ipyradiant.rdf2nx.RDF2NX converter. This would allow users to specify multiple queries that satisfy a stage of the process (e.g. NodeIRIs). The process should use nx.compose to aggregate results and pass them through the normal RDF2NX process.

After discussion with Santiago, we have decided that the following pattern should be sufficient:

if isinstance(cls.node_iris, (list, tuple)):
  node_iris = pd.concat(
    [query.run_query(rdf_graph) for query in cls.node_iris],
    ignore_index=True,
  )
else:
  # run_query
