Ontology Playground is a free, open-source web app that lets you learn about ontologies and Microsoft Fabric IQ by exploring pre-built models or designing your own with a visual editor. You can export your work as RDF/XML, share interactive diagrams, and access 9 structured courses with labs—all without needing a backend. This helps you build and test knowledge graphs safely before implementing them in real systems, saving time and reducing errors in data architecture.
