Could you build this?
Partial The RAG pipeline wrapper is standard, but maintaining temporal consistency and incremental entity invalidation across a dynamic knowledge graph requires specialized knowledge representation engineering.
What it would actually take: Built with Python using graph databases (Neo4j, Memgraph) combined with vector stores (Qdrant, pgvector) and temporal relation extractors. The hard part is temporal entity resolution and conflict invalidation—detecting when newly ingested text obsoletes prior graph nodes or relationships (e.g. tracking valid-time vs. transaction-time). Implementing this requires specialized knowledge of bi-temporal data models and graph-based belief revision algorithms.
