Upstream ownership and mapping

InfoTechCanon supplies shared semantics through the model's import manifest. FIAM supplies the specialized architecture vocabulary through its source manifest. This is a draft local mapping; no upstream ownership transfer is asserted.

FIAM/domain term	Shared owner or disposition	Mapping boundary
InterfaceContract	Local interface specialization; ITC-LAND already seeds Interface	A semantic contract is one aspect of interface architecture; not an exact alias for every landscape Interface.
Endpoint	ITC-LAND seeds Endpoint; local FIAM-qualified usage	The FIAM meaning is the locator of a Binding. Network interfaces and resource selectors are separate.
Participant / SystemNode	Align with ITC-LAND SoftwareSystem/SoftwareComponent where applicable	No blanket equivalence to Actor, host, process, or deployment; choose by modeled scope.
Entity identifier	ITC-IDENT Identifier / Scoped Identifier	FIAM identifier syntax alone does not establish global identity.
same-entity-as	Relate to ITC-IDENT Synonymity Assertion	FIAM query-time equivalence has specific evidence constraints; no destructive merge or automatic cross-canon equivalence.
Assertion	ITC-GOV Assertion	FIAM specializes architectural property/relation assertions with evidence and polarity.
FIAM evidenceRecord	Map to ITC-EVID Evidence plus Evidence Source	FIAM evidenceRecord is support metadata with source, mode and confidence. ITC Evidence is an assertion drawn for a question; source container is separately identified. This is not a one-to-one rename.
Evidence score	ITC-EVID Evidence strength	A FIAM Lens computes a policy-specific heuristic; confidence and support scores are not universal truth probabilities.
Artifact	FIAM describing/implementing artifact role	It may serve as ITC Evidence Source when addressable and versioned; the artifact is not the assertion drawn from it.
Zone / security profile	Reference FIAM contextual classifications	No transfer of generic network, security, trust, tenant, or authorization ownership.
Policy / decision	ITC-GOV Policy / Decision	A Lens finding is an interpretation, not automatically a governed decision or authorization.

Port, Contract Participation, Operation, Binding, Channel, Interaction, Interaction Flow, Information Resource, Information Shape, Resource Selector, Facet, Representation, and Lens receive FIAM-derived interface-domain definitions. Names that overlap other ITC models remain qualified as interface-model:*; this initial import set is not an exhaustive federation ownership audit.

INTERFACE-WP-0003 tracks review of these boundaries, including Information Resource/Shape against ITC-DATA and Artifact against Information Space. Keep publication draft until that review and a concrete consumer proof are complete.
