3	3	The scope of this section is to describe the support in the metamodel for specifying both the access to and the content of a data source. 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.

41	41	Note that, because the //Constraint// can specify a subset of the component values implied by a specific //Structure// (such as a specific DataStructureDefinition or specific MetadataStructureDefinition), the //ConstrainableArtefact//s must be associated with a specific //Structure//. Therefore, whilst the //Constraint// itself may not be linked directly to a DataStructureDefinition or MetadataStructureDefinition, the artefact that it is constraining will be linked to a DataStructureDefinition or MetadataStructureDefinition. A DataProvider and MetadataProvider indirectly refernece DSDs and MSDs through their associated Data and Metadata Provision Agreements as such these Constraints are restricted to Cube Regions and are applicable only to the DSDs / MSDs which contain the Componets being restricted.

66	66	Note also that another possible type of a Constraint is available; that is a AvailableDataConstraint, this is used to report the data that exists in a data source. An AvailableDataConstraint is not a Maintainable Artefact as it is geneated dynamically based on the query. An AvailableDataConstraint contains only 1 Cube Region which is used to specify the valid values per Dimension of the DSD that is is attached to.
