BKN Foundry is the Ontology back-end foundation of OpenBKN. It transforms ontology-driven business semantics into runtime services: data, logic, actions, security governance, and observability.
Automatic Ontology and Knowledge Graph construction with LLM
A Survey on Ontology Engineering, Graph Engineering, Loop Engineering, Harness Engineering, Context Engineering and Prompt Engineering
A package for ontology engineering with deep learning and language models.
Web console for OpenBKN — build, manage, and collaborate on business knowledge networks. React + TypeScript frontend for the platform's admin UIs and workspaces.
Understand what your codebase builds, why it is structured that way, and what a change could affect. One shared Markdown ontology for humans and coding agents—visualized for people, accessible to agents through MCP, and reviewed with Git. Local-first. Open source.
Online tool to automatically generate documentation and evaluation for Ontologies hosted on GitHub
OntoLearner: A Modular Python Library for Ontology Learning with LLMs https://pypi.org/project/OntoLearner/
OntoAligner: A Python Toolkit for Ontology Alignment https://pypi.org/project/OntoAligner/
A curated, versioned collection of OntoUML and UFO conceptual models for research and reuse, with native files, JSON, RDF/Turtle, diagrams, and metadata.
MyKG Knowledge Graph Engine: Turn raw files into knowledge graphs with induced ontology
Draft a company ontology from an uploaded table or document, verify it against every row in code, and keep the person's judgement so the next upload of the same file starts from it
Plow - The ontology package manager
Apps small enough for AI to hold whole. ObjectStack turns the whole app — data model, UI, workflows, permissions — into typed metadata: a complete CRM in under 150k tokens, one context window. Agents read it whole, reason it whole, refactor it whole.
Build, validate, visualize, and publish SKOS taxonomies in your browser — standards-first, single self-contained file, with a REST API and MCP server.
Transform UML into a formal OWL ontology and SHACL shapes
Event-sourced runtime for reconstructable AI identity, memory, reflection, commitments, and auditable cognitive continuity.
