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.

ISO/IEC 11179Standard

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.

ISO/IEC 11179

Stage boundary
No direct role is recorded for Acquire.
Known limitation
The suite is an abstract metamodel rather than a ready-made catalog API; parts version independently, much normative text is not freely available, and useful deployment requires a scoped profile and governance process.

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

Frameworks and metamodels for registering metadata items with governed identification, naming, definitions, classification, mappings, registration status, administration, and dataset descriptions.

Best fitEnterprise or federated registries that must govern the meaning and lifecycle of data elements, concepts, value domains, classifications, and related metadata independently of a storage platform.
