ontology-explorer

separate

Parse, navigate, and query materials science ontology structure (classes, properties, hierarchy). Use when exploring an ontology like CMSO, understanding class relationships, finding properties for a given class, or searching for ontology terms related to a materials science concept. Supports OWL/XML format from the OCDO ecosystem (CMSO, ASMO, CDCO, PODO, PLDO, LDO).

When to use

• exploring ontology structure
• understanding class relationships
• finding properties for a class
• searching for ontology terms
• parsing OWL/XML files
• generating summary JSON

When not to use

• Only supports OWL/XML format (not Turtle, JSON-LD, or N-Triples)
• Does not support OWL reasoning or inference (e.g., does not compute transitive closures)
• Class hierarchy extraction handles simple `rdfs:subClassOf` only (not complex OWL restrictions)
• Descriptions may be missing for classes that lack `rdfs:comment`, `skos:definition`, or IAO annotations
• URL fetching requires internet access and may time out (30-second limit)
