Stanford Ontology 101 methodology for TypeScript domain modeling. 7-step process from competency questions to typed data architectures. Gruber 5 principles. 30+ concept mappings. Works with Claude Code, Cursor, Windsurf.

John, an agent harness designed for building knowledge-dense applications.

This project aims to create an ontology for a university using the Protege editor. The ontology defines various classes and their relationships within the university domain. It also includes queries and rules implemented in Protégé and CLIPS to retrieve information from the ontology.
