Aegir closes OWL ⊨ SKOS ⊨ SHACL and the relational projection.

· weathership

Aegir closes the derivation from certified OWL to populated relational data. The published faces are entailed views of one artifact, not a catalog of generation templates:

  1. OWL — a BFO 2020 / CCO-grounded ontology, HermiT-certified, is the source of truth.
  2. SKOS — the shared type-system key consumed by Atelier and Signals is a projection of realized classes, not an independent glossary.
  3. SHACL — closed-world shapes whose sh:targetClass names those same classes; cardinality and fillers follow the restrictions.
  4. Relational projection — loadable SQL (tables, keys, foreign keys) lowered from the certified OWL, then populated as a textbook corpus with the generator’s reasoning trace beside each chapter.

Every commit is a reproducible snapshot of the whole chain. The artifacts ship from a separate, independently-versioned repository — sdg-corpora — consumed by Aegir, Atelier, and Signals via git submodule.

The phase-gate record lives in the Aegir mdbook under roadmap/phase_gate_governance_ddl.
