What it is
A static web app for learning how ontologies work, built around Microsoft Fabric IQ. It offers a catalogue of ready-made ontologies across domains like retail and healthcare, an interactive graph viewer, and a visual designer for defining entity types, properties, and relationships. Data modelers and students can import RDF/XML, export to RDF/XML, OWL + SHACL, or JSON, and share diagrams by deep link, all without a backend.
