servedIs
servedIs is a term used in theoretical discussions of distributed web architectures to describe a pattern for delivering information states from servers to clients in a stateless interaction. The name merges "served" with IS, standing for Information State, a versioned snapshot of a resource that includes its identity, version, and essential metadata.
Core idea and components: a server exposes information state objects for resources, and clients carry tokens
Mechanisms and semantics: state tokens function similarly to opaque identifiers or ETags but are designed to
Applications and use cases: servedIs concepts can inform API design, content delivery strategies, and edge computing
Limitations and considerations: the approach adds complexity in token management and state synchronization. Security risks exist
