Ontology Explorer

A docs-style browser and hop-based graph visualizer for RDF, RDFS, OWL, SHACL, PROV-O, QUDT, SAREF, and BFO — navigate class hierarchies, inspect SHACL constraints, and explore neighborhoods by hop distance.

Milestone 1, working demo: eight bundled ontologies — RDF, RDFS, OWL, SHACL, PROV-O, QUDT (core schema plus a hand-authored unit sample), SAREF core + SAREF4ENER, and BFO — browsable through a Brick-schema-inspired docs interface (tree nav, search, per-term property tables, SHACL validation panel) and a Connected-Papers-inspired graph view (hop-distance fade-out from a focus term, concentric or force-directed layout, togglable edge types).

The two views are cross-linked in both directions: “Visualize neighborhood” from any term detail page, “Open in Explorer” from any graph node. Built as a fully decoupled sub-app with its own build pipeline, so it can move to its own repository and domain later without touching the rest of this site.

Milestone 2 (not yet built): user-supplied ontologies via clipboard paste, file upload, or URL fetch, plus JSON-LD support — turning the fixed demo dataset into a general-purpose tool.
