Ontology
Definition
Ontology values are the controlled labels used inside a coverage dimension. They keep case classification consistent enough for teams to plan coverage, compare benchmark segments, and explain gaps.
Use this reference when free-form tags are making coverage hard to read or when a benchmark segment needs stable vocabulary before results are trusted. Ontology values remain project-scoped foundations.
Fields, states, or lifecycle rules
- Ontology values belong to dimensions; they should not drift into unrelated free-form tags.
- Values should be specific enough to separate meaningful behavior, but not so narrow that coverage becomes fragmented.
- Changing ontology values can change segment-level benchmark interpretation.
- Ontology should support coverage decisions, not replace expert judgment or policies.
- This page does not define a public taxonomy API.

Interpretation
- Interpretation
- Segment results are easier to trust because the team knows which support condition each case represents.
Source confidence
Code-backed: Dimension types and the Dimension settings, ontology-row, and proposal components establish ontology members as labels owned by a Dimension and used for classification. Vocabulary quality and cross-reviewer consistency require project review.
