Decision support

Compare standards by the job they do

Place up to three profiles side by side. Compare their architectural role, lifecycle reach, and first limitation to test. No single standard covers every layer.

Compare roles before choosing an implementation.

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

  1. Start with the job

    Decide whether you need guidance, a domain payload, exchange, semantics, governance, or a reusable release.

  2. Map lifecycle reach

    Use the matrix to see where each profile has a direct role. A filled cell is coverage, not a quality score.

  3. Test the boundary

    Read what each option leaves unresolved before judging maturity or implementation fit.

Review lifecycle coverage and practical fit.

Read left to right. Lifecycle reach comes first; a maturity label never overrides a scope mismatch.

Where each profile contributes directly

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

What each option does not cover

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

Stage boundary
No direct role is recorded for Plan.
Known limitation
Version 1.0 is new and model rich; adoption and tooling are still scaling, and practical interoperability requires a constrained profile rather than implementing every class.

Check the fit and source behind the map

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

Purpose & coverage

Datum-oriented descriptions of wide, long or event, multidimensional, key-value, and related data structures, plus foundational metadata and detailed process and provenance descriptions.

Best fitCross-domain integration where the same information appears in different structures and each transformation must remain understandable from business process to machine-level operation.
