Bindings package semantic alignments between TSMM and adjacent ecosystems into machine-readable JSON artifacts paired with brief human-readable explanation documents. Each binding now includes a contract section and a per-ecosystem constraint set so the mapping can be reviewed as a bounded translation surface rather than as free-floating prose. Binding status values follow the repo-wide maturity model.
| Binding | Scope | Status | Notes |
|---|---|---|---|
| TRQP binding | Trust registry query and publication surface | Supported | Stable comparison surface for registry and directory workflows |
| OpenID Federation binding | Federation metadata and policy distribution surface | Supported | Stable federation comparison surface |
| DCAS binding | Conformance and assurance evaluation surface | Supported | Suitable for assured-system comparison and evidence portability |
| VTC binding | Verifiable trust community profile surface | Supported | Available for normal comparison use |
| A2A binding | Agent interaction protocol surface | Supported | Aligned to the delivered Agent Interaction Extension |
| OASF binding | Open assurance signal publication surface | Supported | Profile and publication comparison surface |
| AIS-1 binding | Bonded agent identity and accountability substrate | Experimental | Included for comparative modelling, not as a mature or complete trust-stack profile |
| HAVID binding | Composite identifier assurance pattern | Experimental | Useful for comparison while upstream semantics continue to mature |
| ODRL binding | Policy expression and rule-carrier surface | Experimental | Useful for bounded policy modeling without replacing the wider trust meta model |
| GTR GRID/DIA binding | Global registrar discovery and Digital Identity Anchor verification surface | Experimental | Models GRID discovery, registrar authority, DIA verification, lifecycle, revocation, and relying-party effects |
