Standards mapping matrix

This matrix states design intent, not normative compliance.

External concept	PostProject representation	Mapping strength	Adapter status
SMPTE UMID	External identifier on an asset or representation	Intended lossless opaque preservation	Helper deferred
IPTC VMH property	Vocabulary, property, and typed metadata value	Intended lossless for supported value shapes	Mapping package deferred
W3C PROV Entity	Asset or representation, depending on context	Conceptual	Export adapter deferred
W3C PROV Activity	Activity with input and output edges	Strong conceptual mapping	Export adapter deferred
OpenAssetIO Entity Reference	Versioned host-object binding	Manager boundary	Read-only Manager implemented
OpenAssetIO locatable content	Representation, resource, and locator resolution	Strong conceptual mapping	Read-only Manager implemented
OpenAssetIO-MediaCreation image collection	Image-sequence content structure and frame range	Conceptual; evolving traits require versioned adapter review	Image and frame-range traits implemented
OTIO external reference	Representation binding resolved through OpenAssetIO	Partial	Runnable upstream-linker demonstration
OTIO image-sequence reference	Image-sequence descriptor and rational rate	Intended strong mapping	Blocked by upstream linker’s ExternalReference-only support
OTIO rational time	Rational-time value retained by OTIO	Intended exact	Demonstration verifies no transformation
FIMS business-media location	Representation, resource, and locator	Conceptual	Adapter deferred
AAF source/content ID	External identifier	Intended opaque preservation	Adapter deferred
IMF related resources	Package content structure	Conceptual	Adapter deferred
C2PA claim/assertion	Metadata/provenance mapping plus a separate trust layer	Partial	Trust integration deferred

The authoritative specifications, not this table, define each external concept.
