Eclipse Dataspace Protocol

Semantic & Data Protocol

A formal specification defining the schemas, state machines, and interaction patterns required for sovereign, interoperable data sharing between autonomous organizations within a federation of technical systems called a dataspace. Defines three core interaction flows: (1) Catalog — how data assets are published and discovered as DCAT Catalogs with ODRL usage policies; (2) Contract Negotiation — how data usage agreements are syntactically expressed and electronically negotiated between provider and consumer; (3) Data Transfer — how access to data assets is initiated and governed once a contract is agreed. Built on HTTPS as transport and RDF/JSON-LD/Turtle for data semantics. Originally developed by the International Data Spaces Association (IDSA); now standardized through the Eclipse Foundation with ISO/IEC JTC1 SC38 involvement.

Co-Creation & Knowledge

Semantic & Data Protocol Atributos

Origins Industrial data sovereignty / Gaia-X (motivated by European need for sovereign inter-organizational data sharing infrastructure; emerged from IDSA Reference Architecture Model and Rulebook; shaped by Catena-X automotive data space and broader European data economy initiatives including Gaia-X)
Database N/A (protocol specification; implementations typically use relational databases for contract state; no database prescribed by spec)
Query Language SPARQL (via DCAT Catalog federation); ODRL (policy expression); no general query language mandated
Data Formats DCAT (Data Catalog Vocabulary — for publishing data asset catalogs); ODRL (Open Digital Rights Language — for expressing usage policies and contract terms); JSON-LD (primary message encoding); Turtle (RDF schema files); HTTPS (transport binding)
Collaborative Live Editing N/A (protocol specification)
Rich Text Editing N/A
Mobile Support N/A
Web Support N/A
Native Apps N/A
Terms Open / Royalty-free (Eclipse Foundation specification; Apache-2.0 for schemas and TCK; IPR-free per Eclipse governance framework)
Funds Undisclosed (funded through IDSA member contributions and European Commission data space programs; no single public grant amount)
Based On HTTPS (transport); RDF / Linked Data (data model); DCAT (catalog vocabulary); ODRL (policy language); IDS Reference Architecture Model (conceptual predecessor); Gaia-X Trust Framework (trust layer)
Semantic Web Compatibility Full RDF compliance (DCAT and ODRL are W3C standards; JSON-LD encoding; Turtle schema files; SPARQL-compatible catalog queries; designed for semantic interoperability across heterogeneous systems)
Protocol Maturity / Standardization Eclipse Specification / De Facto Standard (Eclipse Specification Project under Eclipse Foundation governance; ISO/IEC JTC1 SC38 involvement for international standardization; W3C standards (DCAT, ODRL) as foundations; widely adopted in European industrial data spaces including Catena-X, Gaia-X; EDC reference implementation compliant Q1 2024)
Vocabulary / Ontology Type Inter-organizational data exchange / Data sovereignty (domain-specific ontology for data asset publication, usage policy expression, contract negotiation, and data transfer governance; not a general-purpose vocabulary)
Usage Pattern Embedded in applications (protocol is consumed by connector implementations — primarily EDC — and data space operators; not used standalone; designed as the interoperability layer beneath data space applications)
