Overview

Shared base for typed n-ary hyperedge member RDF views (GlossPartitiveMember, GlossGenericMember, future leaves).

Carries the shared attributes and the deterministic_id algorithm. Concrete leaves declare their own rdf do block AND their own type-specific attributes — is_delimiting on GlossPartitiveMember (binary role, ISO 704 §5.5.4.2.2); characteristic on GlossGenericMember (delimiting text, ISO 704 §5.5.4.2.1).

Subject identity is content-derived so the same member in the same hyperedge produces the same URI across runs (and across processes). Two members with identical ref + dimensions share a subject — that is intentional: it exposes model-level inconsistency if the same concept is given different dimensions inside the same dataset.

.deterministic_id(member) ⇒ Object

Human-readable SOURCE:ID when both are present; SHA-256 / 16 hex chars fallback otherwise. Same content → same slug across instances, runs, and processes.
