Domain schema

Overview

LOKF’s vocabulary is a short list of classes and typed relations, kept small so that bundles stay portable. Concepts typically stop fitting those classes in a deep or safety-critical domain, such as medicine, law, finance or safety engineering. The answer is then a domain schema written in LinkML that extends LOKF’s. The curator flags concepts that no longer fit, the team decides, and the librarian applies it.

The architecture page says that a domain that extends the schema has its own types checked rather than tolerated (when the built-in vocabulary stops fitting).

Since 0.44.0 one domain schema is released with the sidecar: domain.yaml, for a bundle that federates other bundles, as the curator’s domain-schemas.md says.

A domain schema that grows past a few classes is worth a project of its own, with lint, tests and a docs site. The linkml-sidecar skills install one beside the bundle, or around a schema the repository already holds, as the curator’s domain-schemas.md says since 0.55.1.
