W3C Data Privacy Vocabulary

Maintained by W3C Data Privacy Vocabularies and Controls Community Group

What it helps you do

Use DPV when you need machine-readable concepts for data and processing, purposes, legal bases, parties, recipients, rights, risks, controls, technologies, AI, and jurisdiction-specific laws.

01

Where it fits—and where it doesn’t

Use these four checks before committing implementation time.

Use it when
Privacy and data-protection context for human, genomic, clinical, real-world, and AI datasets where DUO alone is too narrow.
Do not use it as
Do not treat DPV as a complete solution on its own. DPV is a vocabulary, not legal advice or an enforcement engine; local authority, consent, contracts, and jurisdiction-specific interpretation remain controlling.
Best for
Teams working with Clinical and Omics and 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.

  1. InputWhat starts

    Clinical and Omics and AI / ML and Cross-cutting data, metadata, and the local decisions around them

  2. DPVWhat changes

    DPV applies a shared metadata vocabulary across Plan → Acquire → Harmonize → Exchange → Learn + reuse

  3. OutputWhat becomes possible

    A more consistent, reviewable handoff for the next system or team

Readiness gateBefore scaling: DPV is a vocabulary, not legal advice or an enforcement engine; local authority, consent, contracts, and jurisdiction-specific interpretation remain controlling.

03

A concrete example

A governed dataset record pins DPV 2.3 and describes personal-data categories, processing purposes, legal basis, controllers and processors, recipients, retention, risks, measures, and applicable legal context.

Why it matters: Enables automated privacy and permitted-processing screening, but cannot itself establish lawful processing, valid consent, adequate safeguards, or fairness.

04

What it fits with

Can supply domain concepts to ODRL policies and complement DUO, PROV-O, DCAT, RO-Crate, and Croissant metadata.

05

Implementation starter

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

  1. Name an accountable owner and the decision DPV must support.

  2. Pin the exact version and companion artifacts: 2.3 · stable release · 2026-02-28.

  3. Map one representative input to the required metadata vocabulary 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

Limitation to test first—and the tests that catch it

Risk

DPV is a vocabulary, not legal advice or an enforcement engine; local authority, consent, contracts, and jurisdiction-specific interpretation remain controlling.

Test

Run one representative end-to-end pilot and record exactly where DPV 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. Enables automated privacy and permitted-processing screening, but cannot itself establish lawful processing, valid consent, adequate safeguards, or fairness.

07

Why we believe this

Checked against the canonical source plus implementation or adoption evidence reported by the steward or its community.

Evidence notation: E1 + E3. The code is shorthand; the plain-language statement above is the claim.
