DID001Trust List Authority
The governance role that establishes, signs, and publishes the authoritative roster of trusted providers and service states for a defined ecosystem. It exists to make trust decisions discoverable by verifiers without forcing each verifier to build its own provider intelligence.
A machine-readable record describing a provider, its trust status, service category, and qualification context within the directory. The entry is the atomic publication unit that lets downstream systems decide whether a provider can be relied upon.
A publication surface that tracks active, suspended, expired, or withdrawn service states over time. It turns trust administration into an auditable stream rather than a static list.
The controlled issuance of a public signal that a provider or service has satisfied the criteria required for trusted-list inclusion. Trust marks matter because they externalize a directory decision into a reusable machine-readable indicator.
A structured description of the evidence, criteria, and assurance context behind a provider’s inclusion. The record lets relying parties inspect not only who is listed, but why the listing should be accepted.
A compact publication mechanism for exposing provider or credential status changes such as suspension and revocation. It reduces the cost of checking trust freshness at scale.
A signed event stating that a supervisory or registry authority has changed a provider’s standing, scope, or service status. Update notices prevent silent trust drift across dependent systems.
The linkage that makes a local trusted-list entry intelligible across multiple registries, jurisdictions, or ecosystems. Binding is what turns an isolated directory into a transferable trust surface.
An endpoint through which a trusted-list provider exposes certificates, credentials, audit artifacts, or status proofs associated with a listed entity. It separates trust assertions from the evidence needed to verify them.
A machine-oriented interface through which relying systems request provider details, status information, or trust proofs from the directory. The query surface determines how cheaply trust can be consumed operationally.
A signed claim about a provider’s legal identity, authorization, service class, or assurance characteristics. Attribute assertions let a directory describe meaningful trust distinctions without hard-coding them into software.
A published reference to the certificate, key material, or root assertion used to bootstrap verification of trusted-list content. Trust anchor handling is what lets a directory scale beyond implicit bilateral trust.
A machine-readable statement of the geographic, regulatory, or sector boundary within which a listing is valid. Scope markers prevent over-reliance on a trust decision outside its intended domain.
The sequenced record of additions, removals, modifications, and status updates applied to trust directory entries. It is what allows external parties to reconstruct how the directory reached its current state.
A trust directory designed for direct consumption by agents, verifiers, and automated policy systems rather than only by human readers. This is the operational form that makes trusted-list provider infrastructure programmable.
