EM-XCT-09 · Shared contract · W0
Classifications, profiles and crosswalk
A contract for concept schemes, codes, versions, profiles and exact/broad/narrow/related mapping relations.
Partially published; research continues
Claude: study-and-r1-r2-audits-complete; Grok: study-and-r1-r2-audits-complete.
Published results
Research note, in Russian: EM-XCT-09 remains partial: complete scheme authoring and governance; general assignment operations; executable SKOS/XKOS, terminology and profile adapters; production host/IAM/source-custody integration; redaction/federation; existing-Dimension migration and scale. Each requires a separately bounded increment.
Subject boundary and candidate types
- ClassificationScheme
- CodeAssignment
- SemanticMapping
- ProfileConstraint
Deep research questions
- When is a mapping truly exact?
- How to carry over a deprecated code?
- How does a profile preserve identity while narrowing conditions?
Verifiable invariants
- A similar name is not exactMatch
- The classifier version is pinned
- A profile does not change identity silently
End-to-end acceptance scenario
An ambiguous old code triggers a manual-review, and the profile does not admit a prohibited instance.
Negative case
An old world-model ID is automatically replaced with the nearest WM-ID.
Approaches to compare
- Current Vercy protocol/MMAS/whole-object and the published WM-XCT
- W3C PROV/SKOS/SHACL/ODRL where applicable
- Practice of source connectors, versioned schemas and policy enforcement
Candidates in the live catalogue
- WM-XCT-020 · Classification Binding · 0.3.0-research.1 · installable
Semantic fit requires boundary research; a published model does not by itself complete this card. - WM-KNW-018 · Taxonomy / Classification Scheme · 0.3.0-research.1 · installable
Semantic fit requires boundary research; a published model does not by itself complete this card.
Result requirements
Every card is executed together with the full research contract: definitions, fields and cardinalities, lifecycle, sources, data mastership, rights, the five object facets, at least eight invariants, positive and negative examples, dependencies, migration and applicability limits.
