RDF & Neo4j Integration

RDF Standards

  • rdflib-neo4j: RDF to Neo4j mapping
  • SPARQL Queries: Standard semantic queries
  • Linked Data: Interoperable data connections
  • Schema Validation: SHACL constraint checking

Neo4j Enhancement

  • Cypher Queries: Graph-native query language
  • Performance Optimization: Native graph algorithms
  • Real-time Updates: Live data synchronization
  • Vector Embeddings: AI/ML integration support

Semantic Interoperability

Our ontology-driven approach ensures that all data and relationships in the ƒXYZ network are semantically rich, queryable, and compatible with global financial standards.
