Glossary

• A2A - The Agent2Agent protocol developed by Google and now managed by the Linux Foundation. The protocol provides a standard way for agents to collaborate with each other, regardless of the underlying framework or vendor
• Agent - A software service that directly or indirectly uses AI to process requests. Many agents provide an A2A endpoint, and some MCP services use AI which would qualify them as agents too. Agents may also be deeply embedded into existing products such as Google Workspace or Microsoft Word, and the integration is proprietary to the platform.
• Agentic Web - The ability of any AI agent to discover, authenticate, and transact with any other agent on a local/private intranet, or the global Internet.
• AI - Artificial Intelligence is a software system that appears intelligent and that was created using training techniques such as linear regression. The resultant rules that operate the (intelligent) system were not created by humans, but by machines, thus being artificial.
• DID - A Decentralized Identifier as defined by the W3C DID Specification, provides globally unique identifiers encoded as URIs and that resolve to JSON encoded DID documents.
• MCP - The Model Context Protocol is an open-source standard for connecting AI applications to external systems.
