This metric defines criteria to evaluate the extent to which all ontology terms have labels. The metric verifies that ontology terms are labeled using rdfs:label in OWL vocabularies and skos:prefLabel in SKOS vocabularies, ensuring that each term has a human-readable identifier.
What is being measured?
The presence of human-readable labels for all ontology terms, using rdfs:label for OWL vocabularies and skos:prefLabel for SKOS vocabularies.
Why should we measure it?
Having labels for ontology terms improves usability, accessibility, and understanding, making ontologies easier to work with for humans and systems.
What must be provided for the measurement?
An ontology URI.
What are considered valid results?
All ontology terms have labels defined using rdfs:label or skos:prefLabel, ensuring that the ontology is understandable and usable.
