RO-Crate

Maintained by Research Object community

What it helps you do

RO-Crate supports a JSON-LD metadata document that aggregates data, code, workflows, people, instruments, and contextual entities into a research object.

01

Where it fits and where it does not

Use these four checks before committing implementation time.

Use it when
Portable dataset packages, workflow exchange, preservation, publication, and handoff between repositories and compute environments.
Limits
Core conformance is deliberately lightweight; interoperability depends on shared profiles and validation beyond the base crate.
Best for
Discovery and Omics and Cross-cutting teams working across Exchange → Learn + reuse.
Maturity
ScalingUsable now, but adoption or tooling is still developing. Pilot the exact stack first.

02

See it in the workflow

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

  1. InputWhat starts

    Discovery and Omics and Cross-cutting source data, metadata, and local mappings

  2. RO-CrateWhat changes

    Use RO-Crate as a pinned data model / schema across Exchange → Learn + reuse

  3. OutputWhat becomes possible

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

Readiness gateCore conformance is deliberately lightweight; interoperability depends on shared profiles and validation beyond the base crate.

03

A concrete example

A model-training release packages source datasets, preprocessing workflow, environment, outputs, authors, license, and citations.

Why it matters: Bundles the context an agent needs to inspect and reuse a dataset or workflow, but does not standardize table-level ML semantics.

04

What it fits with

Uses Schema.org and Bioschemas terms; profiles add workflow-run or domain detail; PROV-O can deepen lineage.

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 RO-Crate must support.

  2. Pin the exact version and companion artifacts: 1.3 Recommendation · 2026-06-22.

  3. Map one representative input to the required data model / schema 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

Core conformance is deliberately lightweight; interoperability depends on shared profiles and validation beyond the base crate.

Test

Run one representative end-to-end pilot and record exactly where RO-Crate 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. Bundles the context an agent needs to inspect and reuse a dataset or workflow, but does not standardize table-level ML semantics.
