Semantica

What it is

Semantica is a Python library that ingests enterprise data, extracts entities and relationships, and builds knowledge graphs and context graphs that AI agents can query. It supports RDF and property-graph storage, OWL/SHACL/SKOS ontologies, graph analytics, rule-based reasoning, and records decision provenance and audit trails. AI platform and data teams in regulated fields use it as a self-managed semantic layer under their LLMs and vector stores, with LLM use optional and vendor-neutral.
