Exploring GraphRAG Implementations with RDF Knowledge Graphs

Has anyone experience with GraphRag over a RDF store? I am aware of this post https://medium.com/@ianormy/microsoft-graphrag-with-an-rdf-knowledge-graph-part-1-00a354afdb09 but haven't seen anything else. I am particularly interested in graphRAG implementations that can model the resulting KG in RDF, and in approaches that match the extracted entities and relations to an existing KG
