# FIAM derivation

Source: sibling repository `facetted-interfaces`, maintained package
`history/FIAM_v0.2_Draft6/`. [sources.json](sources.json) records the exact Git
commit and SHA-256 for each reviewed artifact. Draft 6 supplies the operating
boundary; its retained Draft 1 explains the frozen Core semantics. Core JSON
pointers in the interface model provide term-level locators; the FIAM Canon
supplies controlled facet and relation terms.

Disposition: adapt the vocabulary into a draft domain model, reference schemas
and conformance upstream, and map shared concepts explicitly. No upstream corpus
is copied here. The source package is a draft in `history/`, not a promoted release.
Do not infer stability from its frozen Core.

Review basis: repository owner request, 2026-09-09; INTERFACE-WP-0002.
Future source updates require changed-definition review and refreshed pins.
