ADR-0002 — Use Horned-OWL for OWL Modeling

Status

Superseded by ADR-0013 for v0.4b+ — v0.1–v0.2 used Oxigraph-based RDF parsing and entity extraction only (ADR-0003).

Context

A Protégé replacement requires OWL 2 awareness and cannot treat everything as anonymous triples.

Decision

Use Horned-OWL as a primary OWL modeling and manipulation dependency where feasible.

Consequences

Positive:

• OWL-specific abstractions
• avoids inventing OWL model from scratch
• better axiom-level workflows

Negative:

• may need adapters for RDF-centric workflows
• may not cover every desired write-back use case

Superseded by

• v0.1–v0.2: Oxigraph + catalog entity extraction (MVP)
• v0.4b+: ADR-0013 dual stack (Oxigraph + Horned-OWL)
