56 56  The constraint mechanism allows specific constraints to be attached to a //ConstrainableArtefact//. With the exception of ReleaseCalendar these constraints specify a subset of the total set of values or keys that may be present in any of the //ConstrainableArtefacts//.

58 -For instance, a DataStructureDefinition specifies, for each Dimension, the list of allowable code values. However, a specific Dataflow that uses the DataStructureDefinition may contain only a subset of the possible range of keys that is theoretically possible from the DataStructureDefinition definition (the total range of possibilities is sometimes called the Cartesian product of the dimension values). In addition to this, a DataProvider that is capable of supplying data according to the Dataflow has a ProvisionAgreement, and the DataProvider may also wish to supply constraint information which may further constrain the range of possibilities in order to describe the data that the provider can supply. It may also be useful to describe the content of a data source in terms of the KeySets or CubeRegions contained within it.

DataConstraint – is used as a mechanism to specify, either the available set of keys (DataKeySet), or set of component values (CubeRegion) in a //DataSource// such as a Simpledatasource or a database (//QueryDatasource//), or the allowable keys that can be constructed from a DataStructureDefinition. Multiple such DataConstraints may be present for a //ConstrainableArtefact//. For instance, there may be a DataConstraint that specifies the values allowed for the //ConstrainableArtefact //(role is allowableContent) which can be used for validation or for constructing a partial code list for one Dimension, while another provides the validation for another Dimension within the same DSD.
