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?”
01
Start with the job
Decide whether you need guidance, a domain payload, exchange, semantics, governance, or a reusable release.
02
Map lifecycle reach
Use the matrix to see where each profile has a direct role. A filled cell is coverage, not a quality score.
03
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.
Readiness-stage coverage for PDBx/mmCIF Exchange Dictionary and Format
The living dictionary is large and revisions can affect parsers, extensions, and optional categories. Syntactic conformance does not establish model quality, biological relevance, or comparability.
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
Structured macromolecular coordinate data and related entities, sequences, assemblies, experimental methods, refinement, citations, software, and archive metadata.
Best fitDeposition, validation, exchange, parsing, and reuse of experimentally determined macromolecular structures across wwPDB and structural-biology toolchains.

AI-ready contribution
Provides typed atom-level structures and experimental context for feature generation, while structure quality, redundancy, biological assemblies, label construction, and train-test separation need independent controls.
First limitation to test
The living dictionary is large and revisions can affect parsers, extensions, and optional categories. Syntactic conformance does not establish model quality, biological relevance, or comparability.
