What it is Filled
Owns scheme identity, namespace, canonical URI, profile, purpose, scope, subject, audience, language, jurisdiction, owner, publisher and steward; immutable releases and change sets; concept identity, scheme membership and top concepts; labels, definitions, notes, examples and notations; broader, narrower and related relations; hierarchy profiles, polyhierarchy, facets, arrays, collections and ordered membership; cross-scheme mappings with versions, method, confidence and provenance; proposal, approval, publication, deprecation, replacement, split, merge and retirement; validation, quality, access, licensing, retention and loss-aware projections. Classified real-world objects, classification bindings, source evidence, policies, workflows, datasets and search indexes remain external.
In scope
- Scheme identity, namespace, profile, scope, authority, release and concept membership
- Labels, definitions, notations, hierarchy, association, facets, collections, mappings, lifecycle and validation
- Provenance, governance, access, licensing, retention and interoperability
Out of scope
- Owning classified objects, classification bindings, evidence, organization, policy, workflow, dataset or search-index lifecycles
- Equating labels with identity, concepts with referents, broader with part-of, closeMatch with exactMatch, or mapping with proved equivalence
- Executing release approval, object reassignment, protected disclosure, external system mutation or irreversible deletion without authority
Why it exists Filled
Represent one governed versioned knowledge-organization scheme containing concept definitions, labels, notations, semantic relations, mappings and release governance.
Distinguishing features Filled
- Holds the scheme and its concepts, not the assignment of concepts to objects, which is the classification binding model.
- A concept has a stable identifier; labels and codes are names for it and may change or repeat.
- Broader and narrower express generality, not part-of; close match is weaker than exact match.
- Differs from an ontology, which defines formal axioms, and from a schema, which defines data structure.
What robots and AI may and may not do Filled
Must not
- Treat a label or code as the identity of a concept.
- Publish or approve a scheme release.
- Delete or redefine a concept that objects are still classified under.
- Assert an exact match where only a close match is supported.
- Reassign classified objects after a scheme change.
Only with a human decision
- Approving a release or a namespace.
- Splitting, merging or deprecating concepts in use.
May
- Propose new concepts, labels and definitions for review.
- Propose candidate mappings to other schemes with a match type.
- Validate a scheme for cycles, orphan concepts and duplicate labels.
- Publish read-only views of an approved release.
Moral aspects Filled
- Categories describing people, such as ethnicity, disability or gender, can stigmatise and need careful wording.
- Classifications decide access to services, statistics and funding, so errors affect real people.
- Offering labels in only one language excludes communities that use others.
Who is affected
- People and groups that the categories describe
- Users and systems that classify with the scheme
- Language communities
- Scheme maintainers
Owners Filled
Steward

Roles
- Dimension owner
- Own namespace, mastership, delegation, access, retention and federation rules.
- Scheme owner or publisher

neighbor
- WM-XCT-020 Classification Binding - A classification binding assigns an external object to a concept in a pinned scheme release. The scheme defines that concept; the registry parent direction appears reversed or navigational and remains held for review.
- Concept and real-world referent - A concept is a unit of thought or authority entry with its own URI. The person, place, product or other referent remains a separate mastered object.
- Ontology and schema - OWL and RDFS can express formal class axioms while SHACL validates graphs. A taxonomy may project to them but does not inherit formal semantics unless the profile declares them.
- Metadata registry - ISO/IEC 11179 defines generic registration, identification, designation, definition, classification and mapping facilities. This model specializes them for a knowledge-organization scheme.
- Vocabulary distribution and dataset - DCAT, DataCite and RO-Crate distributions package or describe a release. They do not replace canonical scheme, concept or mapping identity.
- Search index - An index may tokenize labels and materialize hierarchy for retrieval. Ranking, cache, deployment and query-log lifecycles remain external.
- Mapping assessment - The scheme owns mapping assertions and their status, while evidence and reviewer decisions remain attributable external records. Mapping never silently merges concept identity.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Authoritative master-system identifier for the scheme, concept, mapping, release or change assertion.
- Governed globally resolvable scheme or concept IRI.
- Adopting-Dimension UUID or ULID when no authoritative external identifier exists.
Direct properties not applicable Not applicable
Not applicable
Institutional or informational subject: no invented physical properties.
Recognition optional Filled
- A scheme has a namespace, a set of concepts with identifiers, labels, definitions, hierarchical relations and versioned releases.
- Often confused with an ontology, a code list, a glossary and a classification binding.
Capabilities and actions required Filled
- Register scheme: Create stable scheme identity, namespace, profile, purpose, scope, owner and initial release.
- Define concept: Create or revise one concept with stable identity, definition, characteristics and scheme membership.
- Manage labels and notations: Append language-tagged preferred, alternative or hidden labels, notes and typed notations.
- Relate concepts: Append typed broader, narrower, related or custom semantic relations with explicit hierarchy profile.
- Manage facets and collections: Create facets, arrays, collections, ordered membership and compound structures without changing concept identity.
- Map schemes: Append source-qualified cross-scheme mappings with exact semantics, versions, method and confidence.
- Validate scheme: Run identity, lexical, structural, mapping, quality and profile checks against a pinned release.
- Review and publish change: Review a proposal, append approval or rejection and issue an immutable release and change set.
- Deprecate, split, merge or replace: Append deprecation and successor relations while retaining old identifiers and affected-binding impact.
- Project scheme view: Produce an authorized version-pinned standards projection with declared loss and round-trip limits.
Hazards and failure modes required Filled
- Breaking changes that orphan classified records.
- Wrong mappings that merge distinct concepts.
- Offensive or outdated terms remaining in use.
- Identifiers reused for different meanings.

- ISO 25964 thesauri and interoperability.
- ANSI/NISO Z39.19 controlled vocabularies.
- ISO 1087 terminology work.

Context of use required Filled
- ISO and NISO vocabulary standards, W3C linked-data vocabularies and Library of Congress authority data are complementary profiles rather than universal law.
- Labels, definitions, preferred terms, mapping judgments and publication authority depend on language, community, discipline and jurisdiction.
- ISO 25964 parts are under revision and licensed details require exact release pins before production conformance claims.
