Redefining Knowledge

Collaborative, structured, intelligent — meet the future of knowledge graphs.

What is OpenOntology?

OpenOntology is a platform where intelligent systems don’t just act — they explain.

It transforms knowledge into a structured, versioned, and verifiable asset — no longer hidden in tribal memory or scattered docs.

At its core, OpenOntology unites four disciplines to make knowledge usable by both people and machines:

Semantic Precision

OWL, SHACL — formal structure, validation, machine readability.

Developer Workflow

Markdown, Git, CI/CD — knowledge as versioned, reviewable, and testable code.

LLM Integration

AI that generates, improves, explains, and validates knowledge — grounded, not hallucinated.

Queryable Graph

Structured knowledge that can be queried, analyzed, and reused across teams and agents.

With OpenOntology, your company’s knowledge doesn’t live in people’s heads — it lives in a shared, evolving graph of meaning, accessible to humans and AI alike.

What Makes OpenOntology Unique

Markdown-first

All knowledge is human-readable and versioned as Markdown with YAML metadata.

Git-native workflows

Submit and review knowledge via pull requests, with full CI/CD integration and history.

LLM augmentation

Generate, improve, and explain ontologies with integrated GPT-model support.

Enterprise integration

Export to APIs, GraphQL, DTOs; validate with OWL, SHACL; integrate with GitHub and agents.

Living documentation

Graph visualizations, history diffs, discussions, and annotations — built-in.

Developer-first UX

Designed for engineers: Markdown, Git, REST/gRPC, and schema-first thinking.

How Ontologies Help Business

Structure expertise

Unified formal models for roles, processes, and data. No more knowledge locked in people’s heads.

Reduce errors

Catch ambiguities and duplications early using formal validation and human reviews.

Align systems

Ontology becomes the shared contract between APIs, microservices, and teams.

Power AI reasoning

LLMs reason based on structured, verified knowledge — not scattered notes or outdated docs.

Preserve memory

Build a living knowledge graph that persists beyond individuals or teams.

Automate understanding

Enable agents and systems to "understand" your domain and generate explanations or code.

Why We're Different

OpenOntology unites four powerful domains into one elegant platform:

Semantic Tech

Based on OWL, RDF, and SHACL — precise, formal, and machine-verifiable.

Developer Culture

Markdown, Git, CI/CD — versioning and automation are built into the core workflow.

LLM-native

AI helps generate, explain, and evolve knowledge. GPT supports reasoning and validation.

Knowledge-as-Code

Ontologies live as readable, versioned, structured artifacts — integrated into engineering workflows.

Hallucination-free AI

LLMs grounded in ontologies reason over structured, validated knowledge — not vague or invented facts.

Composable Knowledge

Ontologies are modular and reusable — define once, reference everywhere. Build scalable systems of meaning.

The result: versioned, reviewable, readable knowledge — usable by both humans and machines. Not just an editor. A platform for continuous evolution of collective expertise.
