Limit reference pointc back to ToC or Class ToC

IRI: https://w3id.org/gcdfo/salmon#LimitReferencePoint

A fish stock experiencing serious harm may be depleted to the point where it has impaired productivity or reproductive capacity. As a result, the stock would be less resilient to fishing and could not easily rebuild. Serious harm may be irreversible, or only slowly reversible over the long-term, and can be due to fishing, other human-induced impacts, or natural causes. Under the Precautionary Approach policy and the Fish Stocks Provisions (FSPs), breaching the LRP is a trigger for a rebuilding plan.

IRI: http://www.w3.org/ns/dqv#inDimension

Represents the dimensions a quality metric, certificate and annotation allow a measurement of.
Dimensions are meant to systematically organize metrics, quality certificates and quality annotations. The Data Quality Vocabulary defines no specific cardinality constraints for dqv:inDimension, since distinct quality frameworks might have different perspectives over a metric. A metric may therefore be associated to more than one dimension. However, those who define new quality metrics should try to avoid this as much as possible and assign only one dimension to the metrics they define. More than one dimension can be indicated for each quality annotation or certificate.

The WSP rapid approach can fill gaps by expanding coverage of CU statuses across time, species, and geographic areas.
