This standard specifies a description model, registry mechanisms, and discovery protocols for intelligent agents operating across platforms, organizations, and ecosystems. It defines an agent metadata schema–a machine-readable model for describing agent capabilities, input/output types, semantic and syntactic bindings, version and compatibility policies, a runtime environment, resource constraints, and service bindings. It also specifies registry and lifecycle interfaces, including Application Programming Interfaces (APIs) and data models for agent registration, update, and revocation, together with digital signatures, timestamps, and integrity verification to help ensure traceable and verifiable lifecycle management within interoperable registries. The standard further defines discovery and matching protocols–methods for querying, filtering, ranking, and negotiating agent capabilities based on semantic tags, performance metrics, and version compatibility, as well as support for fallback and degradation strategies. It specifies registry aggregation and consistency–mechanisms for federated and decentralized registry synchronization, caching, conflict resolution, access control, and rate-limiting (ledger-agnostic design). It also defines validation and security mechanisms to detect and mitigate risks arising from invalid, misleading, or malicious agent descriptions, as well as conformance and interoperability testing–including test suites, compliance assertions, and plugfest procedures–for evaluating cross-platform compatibility. Identity frameworks, trust scoring systems, collaborative governance policies, or domain-specific business semantics are beyond the scope of this standard.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
