- ems:metric resources that lack pm:metricQualifier are allowed. They may signal qualification that is implicit from the context.
- If a Performance Monitoring provider exposes any of the metrics below, they MUST be mapped to ems:Measure resources as shown. Other predicates MAY be present, for example dcterms:title; their values are not constrained by the mapping below. Other values of the predicates shown below MAY also be present within the constraints of the resource definition, for example additional qualifier values or RDF types.
