Why should we measure it?
Ensuring metadata accessibility supports reusability, discoverability, and long-term FAIR compliance.
What must be provided for the measurement?
An ontology URI.
What are considered valid results?
Metadata registered and accessible via a persistent public registry such as LOV.
