Summary
Closes #13
Summary
The goal is to provide a protocol-agnostic and standards-aligned discovery mechanism for enumerating multiple AI assets served under a shared origin.
Open Questions
Not AI-specific by design
The API Catalog was designed for general APIs, not AI
assets specifically. Some AI-specific concepts may require additional conventions or profiles.
Risk of inconsistent conventions
Without additional guidance, different implementations may choose different anchor semantics, or
relation types, which could reduce interoperability across catalogs. This could be improved through
further discussion and consensus, for example by recommending specific relation types and stable
schema URIs for assets such as the A2A Agent Card and the MCP Server Card.
Limited expressiveness for rich metadata
The catalog primarily supports discovery and linking. Rich AI metadata must be defined in external
documents such as A2A Agent Cards or MCP Server Cards. A more general or unifying AI Card
specification could be discussed and developed separately within this repository in the future.
