A (% style="color:#e74c3c" %)Constraint(%%) can comprise a list of keys or a list of content (usually [[code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] values) of a specific [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] such as a [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]].

879 -(% style="color:#e74c3c" %)Constraints(%%) comprise the specification of subsets of key or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values that are to be provided for a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] or [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]], or directly attached to a [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] or [[Metadata Structure Definition>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]]. This is important metadata because, for example, the full range of possibilities which is implied by the [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] (e.g., the complete set of valid keys is the Cartesian product of all the values in the [[code lists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] for each of the [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]) is often more than is intended to be supplied according to a specific [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]].

881 -Often a [[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]] will not be able to provide data for all key combinations, either because the combination itself is not meaningful, or simply because the provider does not have the data for that combination. In this case the [[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]] could constrain the [[data source>>doc:sdmx:Glossary 2\.1.Data source.WebHome]] (at the (% style="color:#e74c3c" %)level(%%) of the [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] or the [[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]]) by supplying metadata that defines the key combinations or cube regions that are available. This is done by means of a (% style="color:#e74c3c" %)Constraint(%%). The (% style="color:#e74c3c" %)Constraint(%%) is also used to define a [[code list>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] subset which is used to populate a partial [[code list>>doc:sdmx:Glossary 2\.1.Code list.WebHome]], and in generating a schema for data reporters to validate their [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] against.

883 883  Furthermore, it is often useful to define subsets or views of the [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] which restrict values in some [[code lists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]], especially where many such subsets restrict the same [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. Such a view is called a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], and there can be one or more defined for any [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]].
