The Dataspace Protocol is a specification designed to facilitate interoperable data sharing between entities governed by usage control and based on Web technologies. This specification defines the schemas and protocols required for entities to publish data, negotiate Agreements, and access data as part of a federation of technical systems termed a Dataspace.

This version (2025-1) of the Dataspace Protocol specification is a release of the specification and considered to be stable. Further changes shall not affect conformity. All changes made to the specification can be reviewed in the GitHub repositories - up to and including `2024-1` under the governance of the International Data Spaces Association and with the Eclipse Dataspace Working Group ever since.
