AJP AI Agent Schema Standard — Version History

A formal publication record of all versions of the AJP AI Agent Schema Standard. Each version entry documents the types added, the rationale, and the implementation notes required for adopters to migrate or integrate correctly.

v0.2.0CURRENT2026-04-1820 types

Expands the vocabulary with seven new types covering the full lifecycle of a commercial AI agent: version history, incident reporting, licensing, multi-agent collaboration, third-party endorsement, pricing, and GDPR/POPIA/EU AI Act consent compliance.

RELEASE NOTES
  • AgentIncident: machine-readable evidence standard for agent disputes and boundary violations
  • AgentVersion: hash-chained version history enabling forensic reconstruction of agent changes over time
  • AgentLicence: machine-readable commercial and usage licensing for procurement systems
  • AgentCollaboration: structured description of conductor/worker multi-agent patterns
  • AgentEndorsement: third-party attestation type — natural schema for aiverified.io verification badges; implementations should emit ajp:AgentEndorsement alongside ajp:AgentPassport
  • AgentFee: pricing model declaration for subscription, per-conversation, outcome-based, and hybrid models
  • ConsentDeclaration: GDPR, POPIA, and EU AI Act Article 50 compliance in machine-readable form
v0.1.0STABLE2026-04-1713 types

Initial publication of the AJP AI Agent Schema Standard. Establishes the foundational vocabulary for AI agent identity, capability declaration, cryptographic verification, and deployment accountability. Designed to address the absence of machine-readable agent identity in Schema.org's SoftwareApplication type.
