This metric ensures that a globally unique identifier is assigned to a Research Object so it can be unambiguously referenced by humans and machines.
What is being measured?
A globally unique identifier (GUID) is assigned to a Reserch Object.
Why should we measure it?
Persistent identifiers are are used to ensure that the Research Object can be reliably cited, discovered, and accessed. Assigning a GUID supports reproducibility, traceability, and long-term data stewardship.
What must be provided for the measurement?
A persistent identifier.
What are considered valid results?
Valid results occur when the resource is assigned a globally unique identifier.
