PURL1 metric: Ontology has a persistent URL

This metric evaluates whether the ontology has a persistent URL, ensuring reliable and long-term access.

What is being measured?

The presence of a persistent URL, such as w3id, purl, etc.

Why should we measure it?

Persistent URLs provide a stable reference to the ontology, essential for long-term usability and citation. They ensure that users can reliably access the ontology, even as web structures or hosting services change.

What must be provided for the measurement?

An ontology URI, or a file.

What are considered valid results?

Valid results are ontologies with a registered persistent URL. Examples include a DOI pointing to the ontology publication or a W3ID redirecting to the ontology’s hosting service.
