Overview

Section titled “Overview”

A domain schema is a LinkML schema importing LOKF’s, whose is_a: Concept classes the bundle’s concepts may name in type, checked by lokf validate --schema. Every class is closed, so a concept carries only the slots its class declares, and a concept writes its class name in type exactly.

In KTL mode, the sidecar’s dummy schema is the bundle’s domain schema. A bundle beside any other schema does not make it one: a schema is a domain schema only when .lokf/justfile names it (schema :=) or it imports .lokf/lokf.yaml. An adopted schema is not made one, and its maintainers decide whether to connect it. ktl-librarian’s domain-schema page is the authority on what the validator expects.
