Re: Technical Notes, public web agents

Hi Andrei, Paola

Thanks for sharing, looking for the release of interoperability report.

Here the related works in s-agent-comm CG:

The agent ontology with the currently available documentation is here:
https://github.com/s-agent-comm/agent-ontology

The AgentIDL reference implementation is here:
https://github.com/s-agent-comm/agent-idl

While the ontology layer describes what an agent is (roles, capabilities,
contracts, etc.), AgentIDL defines how an agent acts and speaks. It serves
as a "Semantic API" that can be compared to: OpenAPI/IDL for the web, but
operating at a semantic level. gRPC's .proto files, but with support for
intents, trust, and grammar. Solidity's function signatures, but for agent
behavioral protocols. Semantically, it combines: Ontology (meaning) +
Grammar (syntax) + Protocol (execution) This creates an agent-level
Application Behavior Interface (ABI).
