pnxy

pnxy is a hypothetical open standard and reference implementation designed to facilitate interoperable data exchange across diverse domains in distributed systems. Conceived as a minimal, extensible protocol, pnxy defines how services publish, request, and negotiate access to structured data while preserving privacy and security.

The design emphasizes simplicity and composability: a lightweight protocol layer, a flexible data envelope, and pluggable transport options. The protocol operates over secure channels and supports mutual authentication, token-based access control, and auditable logging. It is intended to be language-agnostic and extensible through optional capabilities that parties may negotiate during a session.

Core concepts include the envelope, which carries metadata about the message; the payload, which contains the actual data expressed according to defined schemas; channels, which act as logical streams for conversations; and negotiable capabilities, which govern allowed operations. Data is envisioned to be encoded in JSON or CBOR, with schemas defined in the PNXY Schema Language (PSL) to promote interoperability and validation.

Architecture of pnxy comprises a core protocol, a set of language-agnostic client libraries, and reference servers or brokers. Implementations provide negotiation, routing, encryption, and access control, with reference deployments illustrating microservice ecosystems, federated analytics platforms, and privacy-preserving data exchanges. A typical pnxy setup involves a client, a broker or server, and a data provider, all operating under agreed governance.

Status and reception: as a hypothetical concept, pnxy appears in academic papers and illustrative examples to demonstrate cross-domain data sharing. There is no official governing body or broad industry adoption. Proponents highlight modularity and governance advantages; critics point to schema harmonization and interoperability challenges across heterogeneous systems.
