A free, open-source static web application for learning about ontologies and Microsoft Fabric IQ. It combines a curated ontology catalogue, a visual ontology designer with full RDF/XML import/export, interactive Cytoscape.js graph diagrams, an embeddable viewer widget, and a structured learning hub — all with zero backend.

Use cases

  • learn ontologies and Microsoft Fabric IQ from scratch
  • design an ontology visually without writing RDF by hand
  • export an ontology as RDF/XML in the format Fabric IQ expects
  • visualize an OWL or RDF ontology as an interactive graph
  • browse example ontologies for domains like retail or healthcare
  • import and edit an existing .rdf or .owl file
  • embed an interactive ontology diagram on a web page

When to choose

  • You want a zero-install, browser-based playground to learn or teach ontology modeling
  • You need to design or round-trip RDF/XML ontologies targeting Microsoft Fabric IQ
  • You want shareable deep links and a single-script embeddable widget for interactive ontology diagrams

When to avoid

  • You need SPARQL querying, OWL reasoners, or a full semantic-web IDE
  • You require backend persistence, user accounts beyond GitHub PR submission, or multi-user collaboration
  • You manage very large enterprise ontologies beyond what a diagram-focused editor handles comfortably
