Dataspace Protocol

Maintained by Eclipse Dataspace Working Group

What it helps you do

DSP supports web-based schemas and protocols for entities to publish data, negotiate usage-controlled agreements, and access data within a federation of technical systems called a dataspace.

01

Where it fits and where it does not

Use these four checks before committing implementation time.

Use it when
Governed exchange across organizational and cloud boundaries where discovery, contract negotiation, and transfer must interoperate without centralizing all data.
Limits
DSP does not define scientific schemas, data quality, federation governance, identity assurance, or every transfer protocol; current implementation evidence is concentrated in the Eclipse dataspace ecosystem.
Best for
Cross-cutting teams working across Exchange → Learn + reuse.
Maturity
ScalingUsable now, but adoption or tooling is still developing. Pilot the exact stack first.

This view shows the input, the change the standard introduces, and the resulting output.

  1. InputWhat starts

    Cross-cutting source data, metadata, and local mappings

  2. DSPWhat changes

    Use DSP as a pinned standard across Exchange → Learn + reuse

  3. OutputWhat becomes possible

    A handoff the next system or team can validate against the same release

03

A concrete example

Expose a participant catalog, negotiate a versioned agreement, record the resulting contract and policy decisions, initiate an agreed transfer process, and retain protocol events as evidence linked to the dataset release.

Why it matters: Enables agents to discover and negotiate governed access to distributed data, while authorization, policy enforcement, semantic compatibility, and fitness checks remain mandatory.

04

What it fits with

Complements DCAT catalog metadata and ODRL usage policies; identity, trust, transfer implementations, and dataset semantics remain companion layers.

05

Implementation starter

Start with one bounded handoff. Pin, test, and review it before scaling.

  1. Define one handoff, its accountable owner, and the decision DSP must support.

  2. Pin the exact version and companion artifacts: 2025-1 · stable; Eclipse 1.0.0 release · 2025-07-23.

  3. Map one representative input to the required standard artifacts.

  4. Test the result against the canonical source and record every exception.

  5. Preserve the source data, mappings, and review evidence before scaling.

06

Test the main limitation

Risk

DSP does not define scientific schemas, data quality, federation governance, identity assurance, or every transfer protocol; current implementation evidence is concentrated in the Eclipse dataspace ecosystem.

Test

Run one representative end-to-end pilot and record exactly where DSP loses context, needs an extension, or depends on another standard.

Risk

Machine-readable output may still be unfit for analysis or ML.

Test

Test the output for missing context, provenance, terminology alignment, time leakage, and the intended downstream decision. Enables agents to discover and negotiate governed access to distributed data, while authorization, policy enforcement, semantic compatibility, and fitness checks remain mandatory.
