GNDIDs

GNDIDs are identifiers used within the GND Identifier System to uniquely reference entities across different contexts. They are designed to be globally unique, persistent, and resolvable by compatible services, so that references to a person, organization, device, or resource remain stable even as systems change.

A GNDID typically consists of a namespace or authority component followed by a local identifier and optional metadata. For example, a form like GNDID-ABC-000123 may be used, where ABC identifies the issuing namespace and the numeric portion is assigned to the specific entity. Some implementations include check digits or version suffixes.

Registration and lifecycle: Identities are issued by authorized registries or authorities, with processes for creation, renewal, revocation, or deprecation. Persistency is emphasized, though revocation policies exist for cases of fraud, error, or compliance concerns. Interoperability relies on published schemas and APIs for validation and lookup.

Governance and security: GNDID governance typically involves a consortium or standards body, with policies on identifier allocation, privacy, data minimization, and abuse handling. Security measures include authentication of issuers, integrity protections for id data, and access controls for registries. Privacy considerations address the exposure of linked personal information in ID usage.

Use cases include cross-system resource referencing in supply chains, digital asset management, identity verification in federated systems, and metadata linking for search and discovery.
