Flexible GraphRAG in Langflow pipeline mode: a SharePoint auto-sync source using Microsoft Graph delta queries, a PDF parsed by LiteParse, and one ingest populating Qdrant vector, Elasticsearch search, Neo4j property graph, and Graphwise GraphDB RDF at the same time, with the processing tab showing initial sync status and AI chat answering questions from an ontology-mode knowledge graph
Flexible GraphRAG v0.8.0 architecture: default, CocoIndex, and Langflow ingest pipelines sharing the same data sources, database targets, UI, and REST / MCP APIs

What it does

  • Hybrid Search. Configurable hybrid search combining vector search, full-text search, property-graph GraphRAG, and SPARQL against RDF stores.
  • Knowledge Graph GraphRAG. Extracts entities and relationships from documents to build graphs in property graph databases and RDF stores. Optional schemas and ontologies guide extraction or act as a starting point for the LLM to extend.
  • RDF/Ontology Support. Load OWL/RDFS ontologies to guide KG extraction into any property graph or RDF store; SPARQL 1.1 queries; RDF 1.2 triple annotations; full UI pipeline (ingest, hybrid search, AI query/chat, incremental auto-sync). See
  • 15 Property Graph Databases. 8 on both LI+LC (Neo4j, ArcadeDB, FalkorDB, Ladybug, Memgraph, NebulaGraph, Amazon Neptune, Neptune Analytics), 1 LI-only (Google Cloud Spanner), 6 LC-only (ArangoDB, Apache AGE, Cosmos Gremlin, HugeGraph, Surre
  • 4 RDF Triple Stores. Apache Jena Fuseki, Ontotext GraphDB, Oxigraph, Amazon Neptune RDF.
