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.

Decision lens

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?”

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 or implementation fit.

Assessment

Review lifecycle coverage and practical fit.

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

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.

CDISC ODM

Stage boundary: No direct role is recorded for Plan, Learn + reuse.
Known limitation: ODM v2 is not backward-compatible in several areas, XML is the currently supplied schema serialization, and schema validity does not prove semantic or regulatory fitness.

03 · Detailed assessment

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	Vendor-neutral exchange and archival of study metadata, subject data, administrative data, reference data, and audit information. Best fitEDC, eClinical, archive, and study-operation transfers where the full operational study record must remain portable alongside submission tables.

AI-ready contribution	Its metadata and audit trail help reconstruct collection context, but analysis features and labels still require CDISC or domain transformations and leakage controls.
First limitation to test	ODM v2 is not backward-compatible in several areas, XML is the currently supplied schema serialization, and schema validity does not prove semantic or regulatory fitness.
