Features

IndentiaDB bundles capabilities that would normally require six separate systems into a single ACID-compliant engine. This section documents every major feature area in depth.

Feature Overview

Feature Description Page
Enterprise Search BM25 full-text indexing with an Elasticsearch-compatible API on port 9200, hybrid BM25+vector search with Bayesian fusion, SPARQL extension patterns for RAG, and access-controlled search with audit logging Enterprise Search
Vector Search & RAG HNSW approximate nearest-neighbour index, SurrealQL and SPARQL vector operators, hybrid text+vector queries, stored-value filtering, Vector K-NN in LPG, and a complete RAG pipeline with Knowledge Graph provenance Vector Search
Graph Algorithms 35 graph algorithms over the LPG projection: community detection (Louvain, Label Propagation), centrality (PageRank, Betweenness, Eigenvector), structural (SCC, bridges, cliques), paths (Dijkstra, A*, Bellman-Ford, k-shortest), flow (Dinic), and more — all via POST /algo/:name Graph Algorithms
Logic Programming (Locy) Datalog-with-Cypher-syntax rule engine: recursive rules, transitive closure, stratified negation, IS-reference joins, and FOLD aggregations — evaluated bottom-up to fixpoint over the LPG Locy Reference
Live Queries LIVE SELECT over WebSocket, DEFINE EVENT triggers, a REST-based SPARQL alerting engine, Rust live-query API with triple-level filtering, and AI agent patterns (inbox, task queue, pub/sub, event sourcing) Live Queries
Federated Queries SPARQL SERVICE clause, SERVICE SILENT fault-tolerant federation, R2RML virtual graphs mapping SQL databases to RDF, and a source registry supporting local, HTTP, and relational sources Federation
Semantic Inference RDFS/OWL forward-chaining materialization with incremental updates, rdfs:subClassOf / rdfs:subPropertyOf / owl:sameAs / owl:equivalentClass support, and configurable per-query inference toggle Inference
Bitemporal Time-Travel Dual-timeline queries (transaction time + valid time), TEMPORAL AS OF, TEMPORAL BETWEEN, and a configurable purge policy for regulatory retention compliance Bitemporal
Geospatial 60-bit geospatial encoding, WKT parsing, GeoSPARQL functions (geof:distance, geof:buffer, geof:within), nearest-neighbour queries, and distance joins Geospatial
Holonic Four-Graph Layer Native Cagle/Koestler holon layer (Interior / Boundary / Context / Meta) on named graphs. SHACL shapes act as formal membranes; /holonic/* routes are opt-in via config with startup guards against cluster mode. Dedicated authz middleware enforces Read for GET and Write for POST; anonymous calls rejected when authn is configured. Holonic

  • If you need graph analytics (community detection, centrality, path analysis): start with Graph Algorithms.
  • If you need recursive inference or logic rules over graph data: start with Locy.
  • If you need real-time dashboards or event-driven automation: start with Live Queries.
  • If you are federating multiple data sources: start with Federation.
  • If you need regulatory audit trails or historical reporting: start with Bitemporal.
