🙈Hidden Label

NEW

Also known as: skos:hiddenLabel

A label used for search indexing that should not be displayed to users in interfaces.

DESCRIPTION

Hidden labels improve retrieval by including misspellings, obsolete names, or internal aliases. They ensure users find concepts even with imperfect queries. Unlike alternative labels, hidden labels are not intended for display. Governance determines when to retire hidden labels and how to track provenance. Careful curation prevents noise and preserves search precision.
