The information may be stored in a resource such as a registry for use by applications wishing to locate data and metadata which are available via the Internet. The //Constraint// is also used to specify a subset of a Codelist which may be used as a partial Codelist, relevant in the context of the artefact to which the //Constraint// is attached e.g., DataStructureDefinition, Dataflow, ProvisionAgreement, MetadataStructureDefinition, Metadataflow, MetadataProvisionAgreement.
