OUDEA

Open Unified Data Exchange Architecture

OUDEA defines an architecture for decentralized discovery, exchange, and processing of structured data across domain-based ecosystems. It combines domain-governed schemas, canonical data spaces, and open protocols to support interoperable, machine-readable data networks.

About OUDEA

OUDEA provides a governed architecture for publishing, discovering, exchanging, and processing structured data without dependence on a central platform. Domains act as schema authorities, while federated data rooms and implementations enable interoperable exchange.

Core principles

Domain authority

Domains define canonical namespaces, schemas, and publication points.

Structured interoperability

Data is exchanged using shared schemas and machine-readable contracts.

Federated infrastructure

Independent systems can host, exchange, and process OUDEA-compatible data.

Open implementations

Anyone may build software implementing OUDEA, while the specification remains canonical.

Documentation

The normative OUDEA specification is published under /spec/. Human-readable schema and implementation materials may be published separately under OUDEA domains and repositories.

The first reference implementation of OUDEA is bytEM.

Alpha status

This site is the alpha publication environment for OUDEA. Structure, terminology, and specification content are still evolving.
