Data Readiness Knowledge Base

01

Where it fits—and where it doesn’t

Use these four checks before committing implementation time.

Use it when: Human-facing readiness and release documentation for clinical, imaging, omics, laboratory, and real-world ML datasets.
Do not use it as: Do not treat Data Cards as a complete solution on its own. There is no single mandatory schema or conformance test; narrative claims require linked evidence, ownership, review, and update controls.
Best for: Teams working with AI / ML and Cross-cutting data across Plan → Acquire → Harmonize → Exchange → Learn + reuse.
Maturity: ScalingUsable today, with adoption or tooling still scaling; pilot the exact stack you plan to run.

02

See it in the workflow

A standard creates value by changing a handoff, not by existing in a catalog.

InputWhat starts
AI / ML and Cross-cutting data, metadata, and the local decisions around them
Data CardsWhat changes
Data Cards applies a shared framework across Plan → Acquire → Harmonize → Exchange → Learn + reuse
OutputWhat becomes possible
A more consistent, reviewable handoff for the next system or team

Readiness gateBefore scaling: There is no single mandatory schema or conformance test; narrative claims require linked evidence, ownership, review, and update controls.

03

A concrete example

A release card documents provenance, sample or cohort construction, annotation and QC, split design, intended and out-of-scope uses, relevant coverage and performance evidence, risks, and version changes.

Why it matters: Makes the rationale and limitations that determine responsible reuse visible to human reviewers, while companion machine-readable metadata is still required for automation.

04

What it fits with

Complements machine-readable Croissant and SPDX records, ISO/IEC 5259 quality evidence, and NIST AI RMF governance; Datasheets for Datasets is a closely related predecessor.

05

Implementation starter

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

Name an accountable owner and the decision Data Cards must support.
Pin the exact version and companion artifacts: 2022 framework + playbook.
Map one representative input to the required framework artifacts.
Test the result against the canonical source and record every exception.
Preserve the source data, mappings, and review evidence before scaling.

06

Limitation to test first—and the tests that catch it

Risk

There is no single mandatory schema or conformance test; narrative claims require linked evidence, ownership, review, and update controls.

Test

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

Risk

A structured or machine-readable result can still be unfit for analysis or AI.

Test

Test the output for missing context, provenance, terminology alignment, time leakage, and the intended downstream decision. Makes the rationale and limitations that determine responsible reuse visible to human reviewers, while companion machine-readable metadata is still required for automation.

07

Why we believe this

Checked against the canonical source, with knowledge-base analysis clearly separated from publisher claims.

Evidence notation: E1 + E4. The code is shorthand; the plain-language statement above is the claim.
