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.

OECD OHTs

Stage boundary: No direct role is recorded for Plan.
Known limitation: The suite has no single version, and OHT fields are not themselves regulatory data requirements. Exact templates, schemas, picklists, test guidelines, IUCLID release, and jurisdictional profile must be frozen.

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.

Detailed comparison of OECD Harmonised Templates
Assessment	OECD OHTsOECD Harmonised Templates
Purpose & coverage	Structured chemical test summaries for physicochemical properties, environmental fate, effects on biotic systems, human health effects, pesticide residues, analytical methods, efficacy, intermediate effects, use, and exposure. Best fitChemical safety and regulatory programs that exchange endpoint study summaries across databases, jurisdictions, and IUCLID-based workflows.
Readiness stages	AcquireHarmonizeExchangeLearn + reuse
AI-ready contribution	Creates structured endpoint and method context for evidence synthesis, while study-summary data can omit raw observations and cannot by itself establish reliability, bias control, or comparability.
First limitation to test	The suite has no single version, and OHT fields are not themselves regulatory data requirements. Exact templates, schemas, picklists, test guidelines, IUCLID release, and jurisdictional profile must be frozen.
Maturity	Established Internationally maintained data formats with XML schemas and a complete IUCLID implementation
