A Rust-based MCP server and desktop studio for AI-native ontology engineering with lifecycle management and reasoning.
Build, validate, and reason over AI-generated ontologies.
Manage ontology lifecycle with Terraform-style workflows and versioning.
Query, align, and enrich ontologies with semantic embeddings and clinical crosswalks.
Open Ontologies is a Rust MCP server and desktop Studio that enables AI agents to build, validate, classify, query, and govern RDF/OWL ontologies using an in-memory Oxigraph triple store. It offers 48 tools for ontology lifecycle management, reasoning, semantic embeddings, and versioning, wrapped in a visual desktop app with 3D graph visualization and AI chat. The server supports Terraform-style change management, a marketplace of 29 standard ontologies, clinical crosswalks, and a full audit trail, all without requiring JVM or Protégé.
