Decision support

Compare standards by the job they do

Place up to three profiles side by side. Focus on architectural role, evidence, and the first limitation to test—not on finding a single all-purpose standard.

Decision lens

Compare roles before you compare maturity.

The useful question is not “Which standard wins?” It is “Which job must this part of the architecture perform, and what remains uncovered?”

Start with the job
Decide whether you need guidance, a domain payload, exchange, semantics, governance, or a reusable release.
Map lifecycle reach
Use the matrix to see where each profile has a direct role. A filled cell is coverage, not a quality score.
Test the boundary
Read what each option leaves unresolved before judging maturity, confidence, or implementation fit.

Three-part assessment

See the reach, the gaps, and the evidence.

Read left to right. Lifecycle reach comes first; maturity remains an editorial roll-up, not certification.

01 · Lifecycle reach

Where each profile contributes directly

Coverage shows a recorded role at that readiness stage. It does not imply end-to-end implementation.

02 · Boundaries

What each option does not cover

These are design boundaries, not faults. Use them to identify the companion layers your architecture still needs.

DPV

Stage boundary: No direct stage gap is recorded. Lifecycle reach still does not make this an end-to-end implementation.
Known limitation: DPV is a vocabulary, not legal advice or an enforcement engine; local authority, consent, contracts, and jurisdiction-specific interpretation remain controlling.

03 · Detailed assessment

Check the fit and evidence behind the map

Use the source, status, and limitation together. A higher maturity label does not erase a scope mismatch.
