Design Term Relations
Typed semantic relation model between design terms from different named sources, and the term record shape.

Repository Boundary
This guide defines the closed set of typed relations used to judge how two design terms relate, and the shape of a term record. It does not decide which external definition is correct, and its types never rename StyleGallery's own terms. Relations are judgments recorded with evidence, not standards.
Reusable Method
- Record both terms with their sources, kinds, and concepts.
- Choose exactly one relation type from the closed set below.
- Write the boundary statement: the specific scope in which the relation holds and where it breaks.
- Stamp
reviewed_on; a relation without a date is unverified. - Re-verify the relation whenever either source revises the term.
Relation Types
| Relation type | Meaning | Invariants | Required boundary statement |
|---|---|---|---|
equivalent_within_scope |
The two terms denote the same concept inside one named scope | Symmetric; a named scope must exist and be recorded | The scope, and what changes outside it |
near_equivalent |
Mostly overlapping meaning with known divergences | Symmetry must be declared per record; the axis creating the divergence must be named | The divergences and their axis |
partial_overlap |
Some instances satisfy both terms; others satisfy only one | Symmetric; both the common region and each non-common region must be recorded | Which instances fall on each side |
broader_than |
The first term's extension properly contains the second's | Directional; the reverse side must hold narrower_than when recorded from the other term; a counterexample direction must exist |
The contained region and a counterexample direction |
narrower_than |
Inverse of broader_than |
Directional; must be the inverse of the paired broader_than record |
Same as above, inverted |
implementation_representation |
One term is a way the other is serialized, stored, or consumed | Directional and fixed: the from-term is the representation, the to-term is the semantic concept; the direction must not flip between records of the same pair | The representation direction and what is lost or added |
renamed_to |
A source replaced one label with another | Intra-source temporal: both terms must belong to one named source, with a dated or versioned rename event | The rename event and both statuses |
deprecated_in_favor_of |
A source withdrew one term in favor of another | Requires a deprecation basis and a replacement source of record | The withdrawal scope and migration note |
same_label_different_meaning |
Identical labels, distinct concepts | Requires evidence that label is identical while concept or scope differs | Both meanings and the confusion risk |
not_comparable |
No meaningful relation holds at the cited scopes | Symmetric; the comparison axis that fails must be named | Why comparison fails |
Forbidden Error States
A relation record is invalid when any of the following holds:
- The same term pair records
broader_thanandnarrower_thansimultaneously in one direction (these are inverse views, not two facts). - The same pair and scope records
equivalent_within_scopeandnot_comparable(or any other contradiction) at once. renamed_tolacks a time or version basis for the rename event.- Either term lacks an official, named source.
- The boundary field is empty or restates the type without adding scope.
The Markdown validator enforces unique source-qualified term IDs, direct source locators, actual calendar dates, explicit scope and direction, identical labels for same_label_different_meaning, temporal status/event requirements, inverse consistency, and acyclic containment within each scope. It ignores fenced examples and HTML comments. Locators must be HTTPS or existing repository documents; the validator does not authenticate source ownership or evaluate semantic truth.
The term table has seven columns: identifier, label, source/kind with direct locator, concept, status, scope, and reviewed date. The relation table has seven: from, to, type, scope, direction, boundary, and reviewed date. Scope is a non-empty kebab-case comparison identifier. One directed pair has one relation per scope; a separately recorded inverse must agree. Symmetric types use symmetric; representation, containment, and temporal relations use directional; near_equivalent declares either explicitly. Self-relations are invalid. Boundaries must contain a substantive sentence; a length check can reject blanks but cannot establish semantic adequacy.

Exportable design values overlap; prototype values need not be
tokens, and one scalar variable does not provide every composite
structure in the 2025.10 format.In v0.1 this shape is authored as the Markdown tables in Cross-System Term Cases. A machine-readable registry holding terms, concepts, sources, and relations is a prerequisite for promoting this domain beyond experimental; until then Material v2 answers document search only, not structured crosswalk queries.
Opinionated Guidance
- One relation type per pair, per scope; two relations for the same pair require two named scopes.
partial_overlapwith a stated boundary beats an unqualified equivalence.- A relation between different source kinds must say what the kind difference contributes.
- Reject a recorded relation whose boundary restates the type without adding scope.
Platform-Specific Guidance
Relations involving a platform guideline source cite that platform's surface; deeper convention comparison routes to Platform Guides.
Unsupported Absolutes
- A relation is not a standard and binds no source.
- Popularity does not decide
broader_than. - Tool-layer feature names do not settle system-layer relations.
- Absence of a relation between two terms is not evidence of equivalence.
Verification Contract
Every recorded relation names two term records, one type from the closed set, a non-trivial boundary, and a review date; verify both sources still use the terms as recorded before promotion.

This page is a locally authored model. The illustrative figma.variable and dtcg.token relation uses partial_overlap; its named sources were rechecked on 2026-09-08 as recorded in Term Cases. No upstream prose is reproduced.
