README

Dataspace Protocol

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.

The web rendering of the Dataspace Protocol represents the current state on this repo's main branch: https://eclipse-dataspace-protocol-base.github.io/DataspaceProtocol/.

About versions

Previous versions of the Dataspace Protocol (0.8 and 2024-1) have been developed and released under the governance of the International Data Spaces Association (IDSA).

Subsequent versions of the Dataspace Protocol are maintained and developed within the Eclipse Dataspace Protocol project associated with the Eclipse Dataspace Working Group, under the governance of the Eclipse Foundation (EF). Version 2024-1 marks the initial contribution to the Eclipse Dataspace Protocol project by the IDSA.
