markdown

The CommonMark literal datatype — documentation content carried in the graph is CommonMark, typed with this datatype so the convention is machine-visible. Used ONLY in annotation literals (scope notes, examples, guide content), never in logical axioms, so the OWL 2 DL profile is untouched. HTML or SGML subsets are explicitly rejected: one markup convention, visible in the data.

Practical Pattern

Use gmeow:markdown when the definition matches the source fact. Prefer a narrower GMEOW term when one exists, and keep projection concerns in the mapping layer.
