In this line PyCharm complains about a wrong type: "Expected type 'URIRef', got 'Node' instead". I am not sure how to solve this, the return type of graph.triples(..) is Tuple[Node, Node, Node] which is pretty general. parse_implicit_relationship expects a URIRef which should be fulfilled if the rdf file is valid. The only solution I could think of is to accept a Node as input and check if element_node is a URIRef in parse_implicit_relationship and log an error if this is not the case. Any other suggestions on how to fix this are much appreciated.

I think your proposal is the right way to go. We can't expect a "random" triple from the parsed RDF graph to be a URIRef, so we have to make sure that we get the correct type. I'm curious, though, why this doesn't pop up in other uses of graph.triples().

I added a wrapper method for the graph.triples(..) and also for graph.value(..) to ensure types at some places. I decided to write a Warning in the logger if the type doesn't match as the code would probably run either way.
