Missing Obsolete Label

Problem: An obsolete entity does not have a label beginning with “obsolete”. Adding this prefix ensures that users are aware the entity has been deprecated.

Solution: Add the “obsolete” (or “OBSOLETE”) prefix.

PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT DISTINCT ?entity ?property ?value WHERE {
  VALUES ?property { rdfs:label }
  ?entity owl:deprecated true .
  ?entity ?property ?value .
  FILTER (!regex(?value, "^obsolete", "i"))
  FILTER (!isBlank(?entity))
}
ORDER BY ?entity
