How to read the register

Semantic home

Every resource belongs to exactly one bounded, common or scheme context. A context owns its internal meaning; the common boundary is deliberately exceptional and small.

Direct and structural traces

Direct traces motivated the term itself. Structural traces reach an organising superclass through its descendants. They are shown separately so inherited evidence is never mistaken for direct evidence.

Candidate definitions

Definitions are machine-proposed modelling statements for working-group review. They do not replace the original source wording shown in the data dictionary.
