	5	== 12.1 Scope ==
	6
13.1	7	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>>doc:Glossary.Data source.WebHome]]. 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 (% style="color:#e74c3c" %)//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>>doc:Glossary.Artefact.WebHome]] to which the (% style="color:#e74c3c" %)//Constraint//(%%) is attached e.g., DataStructureDefinition, [[Dataflow>>doc:Glossary.Dataflow.WebHome]], ProvisionAgreement, MetadataStructureDefinition, [[Metadataflow>>doc:Glossary.Metadataflow.WebHome]], MetadataProvisionAgreement.
2.1	8
13.1	9	Note that in this metamodel the term [[data source>>doc:Glossary.Data source.WebHome]] refers to both data and metadata sources, and [[data provider>>doc:Glossary.Data provider.WebHome]] refers to both data and metadata providers.
2.1	10
13.1	11	A [[data source>>doc:Glossary.Data source.WebHome]] may be a simple file of data or metadata (in [[SDMX-ML>>doc:Glossary.SDMX-ML.WebHome]], JSON or other format), or a database or [[metadata repository>>doc:Glossary.Metadata repository.WebHome]]. A [[data source>>doc:Glossary.Data source.WebHome]] may contain data for many data or [[metadata flows>>doc:Glossary.Metadataflow.WebHome]] (called [[Dataflow>>doc:Glossary.Dataflow.WebHome]], and [[Metadataflow>>doc:Glossary.Metadataflow.WebHome]] in the model), and the mechanisms described in this section allow an organisation to specify precisely the scope of the content of the [[data source>>doc:Glossary.Data source.WebHome]] where this [[data source>>doc:Glossary.Data source.WebHome]] is registered (SimpleDataSource, //QueryDataSource//).
2.1	12
13.1	13	The [[Dataflow>>doc:Glossary.Dataflow.WebHome]] and [[Metadataflow>>doc:Glossary.Metadataflow.WebHome]], themselves may be specified as containing only a subset of all the possible keys that could be derived from a DataStructureDefinition or MetadataStructureDefinition. Respectively, further subsets may be defined within a ProvisionAgreement and MetadataProvisionAgreement.
2.1	14
12.1	15	These specifications are called (% style="color:#e74c3c" %)//Constraint//(%%) in this model.

	28
13.1	29	Any [[artefact>>doc:Glossary.Artefact.WebHome]] that inherits from the //ConstrainableArtefact// interface can have (% style="color:#e74c3c" %)constraints(%%) defined. The [[artefacts>>doc:Glossary.Artefact.WebHome]] that can have (% style="color:#e74c3c" %)constraint(%%) metadata attached are:
2.1	30
	31	Dataflow
	32	ProvisionAgreement
	33	DataProvider – this is restricted to release calendar
	34	DataStructureDefinition
	35	Metadataflow
	36	MetaDataProvider – this is restricted to release calendar
	37	MetadataProvisionAgreement
	38	MetadataSetMetadataStructureDefinition
13.1	39	SimpleDataSource – this is a registered [[data source>>doc:Glossary.Data source.WebHome]] where the registration references the actual [[Data Set>>doc:Glossary.Data set.WebHome]] or Metadata Set
2.1	40	//QueryDataSource//
	41
13.1	42	Note that, because the (% style="color:#e74c3c" %)//Constraint//(%%) can specify a subset of the [[component>>doc:Glossary.Component.WebHome]] 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 (% style="color:#e74c3c" %)//Constraint//(%%) itself may not be linked directly to a DataStructureDefinition or MetadataStructureDefinition, the [[artefact>>doc:Glossary.Artefact.WebHome]] that it is constraining will be linked to a DataStructureDefinition or MetadataStructureDefinition. As a DataProvider or a MetadataProvider does not link to any one specific [[DSD>>doc:Glossary.Data structure definition.WebHome]] or [[MSD>>doc:Glossary.Metadata structure definition.WebHome]] the type of information that can be contained in a (% style="color:#e74c3c" %)Constraint(%%) linked to a DataProvider/MetadataProvider is restricted to ReleaseCalendar.

	55
12.1	56	The (% style="color:#e74c3c" %)constraint(%%) mechanism allows specific (% style="color:#e74c3c" %)constraints(%%) to be attached to a //ConstrainableArtefact//. With the exception of ReleaseCalendar these (% style="color:#e74c3c" %)constraints(%%) specify a subset of the total set of values or keys that may be present in any of the //ConstrainableArtefacts//.
2.1	57
13.1	58	For instance, a DataStructureDefinition specifies, for each [[Dimension>>doc:Glossary.Dimension.WebHome]], the list of allowable [[code>>doc:Glossary.Code.WebHome]] values. However, a specific [[Dataflow>>doc:Glossary.Dataflow.WebHome]] 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>>doc:Glossary.Dimension.WebHome]] values). In addition to this, a DataProvider that is capable of supplying data according to the [[Dataflow>>doc:Glossary.Dataflow.WebHome]] has a ProvisionAgreement, and the DataProvider may also wish to supply (% style="color:#e74c3c" %)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>>doc:Glossary.Data source.WebHome]] in terms of the KeySets or CubeRegions contained within it.
2.1	59
12.1	60	A //ConstrainableArtefact// can have two types of (% style="color:#e74c3c" %)//Constraint//(%%)s:
2.1	61
13.1	62	1. DataConstraint – is used as a mechanism to specify, either the available set of keys (DataKeySet), or set of [[component>>doc:Glossary.Component.WebHome]] 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>>doc:Glossary.Code list.WebHome]] for one [[Dimension>>doc:Glossary.Dimension.WebHome]], while another provides the validation for another [[Dimension>>doc:Glossary.Dimension.WebHome]] within the same DSD.
	63	1. MetadataConstraint – is used as a mechanism to specify a set of [[component>>doc:Glossary.Component.WebHome]] values (MetadatTargetRegion) in a //DataSource// such as a MetadataSet or a database (//QueryDatasource//). Multiple such MetadataConstraints may be present for a //ConstrainableArtefact//. For instance, there may be a MetadataConstraint that specifies the values allowed for the //ConstrainableArtefact //(role is allowableContent) which can be used for validation or for constructing a partial [[code list>>doc:Glossary.Code list.WebHome]], whilst another MetadataConstraint can specify the actual content of a metadata source (role is actualContent).
2.1	64
12.1	65	In addition to DataKeySet and/or CubeRegion/MetadataTargetRegion a (% style="color:#e74c3c" %)Constraint(%%) can have a ReleaseCalendar specifying when data or metadata are released for publication or reporting.
2.1	66
13.1	67	Note also that another possible type of a DataConstraint is available; that is a DataConstraint with the role of actualContent where it describes the data that an [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] Web Service contains. This type of DataConstraint is not maintained in a Registry and is always a response to the data availability [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] REST API. Thus, its identification is autogenerated by the service responding to a data availability request.

	75	==== 12.3.3.1 Explanation of the Diagram ====
	76
12.1	77	A (% style="color:#e74c3c" %)//Constraint//(%%) is a //MaintainableArtefact//.
2.1	78
	79	A DataConstraint has a choice of two ways of specifying value subsets:
	80
13.1	81	1. As a set of keys that can be present in the //[[DataSet>>doc:Glossary.Data set.WebHome]]// (DataKeySet). Each DataKey specifies a number of ComponentValues each of which reference a //[[Component>>doc:Glossary.Component.WebHome]]// (e.g., [[Dimension>>doc:Glossary.Dimension.WebHome]], DataAttribute). Each ComponentValue is a value that may be present for a //[[Component>>doc:Glossary.Component.WebHome]]// of a structure when contained in a //[[DataSet>>doc:Glossary.Data set.WebHome]]//. In addition, each DataKeySet may also include MemberSelections for AttributeComponents or [[Measures>>doc:Glossary.Measure.WebHome]].
	82	1. As a set of CubeRegions each of which defines a “slice” of the total structure (MemberSelection) in terms of one or more MemberValues that may be present for a //[[Component>>doc:Glossary.Component.WebHome]]// of a structure when contained in a //[[DataSet>>doc:Glossary.Data set.WebHome]]//.
2.1	83
13.1	84	The difference between (1) and (2) above is that in (1) a complete key is defined whereas in (2) above the “slice” defines a list of possible values for each of the// [[Component>>doc:Glossary.Component.WebHome]]//s but does not specify specific key combinations. In addition, in (1) the association between //[[Component>>doc:Glossary.Component.WebHome]]// and DataKeyValue is constrained to the [[components>>doc:Glossary.Component.WebHome]] that comprise the key, whereas in (2) it can contain other [[component>>doc:Glossary.Component.WebHome]] types (such as AttributeComponents or [[Measures>>doc:Glossary.Measure.WebHome]]). By adding MemberSelections to the DataKeySets of (1), AttributeComponents and [[Measures>>doc:Glossary.Measure.WebHome]] are constrained for the related DataKeys.
2.1	85
	86	A MetadataConstraint has only one way of specifying value subsets:
	87
13.1	88	~1. As a set of MetadataTargetRegions each of which defines a “slice” of the total structure (MemberSelection) in terms of one or more MemberValues that may be present for a //[[Component>>doc:Glossary.Component.WebHome]]// of a structure when contained in a MetadataSet.
2.1	89
13.1	90	In both CubeRegion and MetadataTargetRegion, the value in ComponentValue.value and MemberValue.value must be consistent with the //[[Representation>>doc:Glossary.Representation.WebHome]]// declared for the //[[Component>>doc:Glossary.Component.WebHome]]// in the DataStructureDefinition ([[Dimension>>doc:Glossary.Dimension.WebHome]] or DataAttribute) or MetadataStructureDefinition (MetadataAttribute). Note that in all cases the "operator" on the value is deemed to be "equals", unless the wildcard character is used '%'. In the latter case the "operation" is a partial matching, where the percentage character ('%') may match zero or more characters. Furthermore, it is possible in a MemberValue to specify that child values (e.g., child [[codes>>doc:Glossary.Code.WebHome]]) are included in the (% style="color:#e74c3c" %)Constraint(%%) by means of the cascadeValues [[attribute>>doc:Glossary.Attribute.WebHome]]. The latter may take the following values:
2.1	91
	92	* "true": all children are included,
	93	* "false" (default), or
13.1	94	* " excludeRoot", where all children are included, and the root [[Code>>doc:Glossary.Code.WebHome]] is excluded (i.e. the referenced [[Code>>doc:Glossary.Code.WebHome]]).
2.1	95
13.1	96	It is possible to define for the DataKeySet, DataKey, CubeRegion, MetadataTargetRegion and MemberSelection whether the set is included (isIncluded = "true", default) or excluded (isIncluded = "false") from the (% style="color:#e74c3c" %)Constraint(%%) definition. This [[attribute>>doc:Glossary.Attribute.WebHome]] is useful if, for example, only a small sub-set of the possible values are not included in the set, then this smaller sub-set can be defined and excluded from the (% style="color:#e74c3c" %)constraint(%%). Note that if the child construct is “included” and the parent construct is “excluded” then the child construct is included in the list of constructs that are “excluded”.
2.1	97
13.1	98	In any MemberSelection that the corresponding //[[Component>>doc:Glossary.Component.WebHome]]// was using Codelist with extensions, it is possible to remove the prefix that has been used, in order to refer to the original [[Codes>>doc:Glossary.Code.WebHome]]. This is achieved via property removePrefix, which defaults to “false”.
2.1	99
	100	In DataKeys and MemberValues it is possible, via the validFrom and validTo properties, to set a validity period for which the selected key or value is constrained.
