protocolrich
Protocolrich is an open standard designed to enable interoperable, metadata-rich data exchange in distributed computing environments. It defines a uniform envelope for messages, a scheme for identifying resources, and a framework for expressing rich metadata graphs alongside payloads. The design emphasizes extensibility, transport-agnostic semantics, and support for diverse domains such as research data, digital repositories, and Internet of Things ecosystems.
Origins of Protocolrich trace to community-led efforts in the early 2020s to unify metadata exchange across
Core concepts include resource identifiers (RIDs), message envelopes with versioned headers, payloads, and metadata graphs. A
Security and governance are central to Protocolrich. Messages can be signed to verify integrity and origin,
Applications include digital libraries, scientific data sharing, metadata catalogs, and edge-device ecosystems. Benefits include improved discovery,
