5 == 5.1 Introduction ==
6
7 The DataStructureDefiniton is the class [[name>>doc:IMElements.name.WebHome]] for a [[structure>>doc:IMElements.structure.WebHome]] definition for data. Some organisations know this [[type>>doc:IMElements.type.WebHome]] of definition as a “[[Key>>doc:IMElements.AnnotableArtefact.Key.WebHome]] Family” and so the two names are synonymous. The term [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] (also referred to as [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]) is used in this specification.
8
9 Many of the constructs in this layer of the model inherit from the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Base Layer. Therefore, it is necessary to study both the inheritance and the relationship diagrams to understand the functionality of individual packages. In simple sub models these are shown in the same diagram but are omitted from the more complex sub models for the sake of clarity. In these cases, the inheritance diagram below shows the full inheritance tree for the classes concerned with [[data structure definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]].
10
11 There are very few additional classes in this sub model other than those shown in the inheritance diagram below. In other words, the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Base gives most of the [[structure>>doc:IMElements.structure.WebHome]] of this sub model both in terms of associations and in terms of [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]. The relationship diagrams shown in this section show clearly when these associations are inherited from the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Base (see the Appendix “A Short Guide to UML in the [[SDMX Information Model>>doc:sdmx:Glossary 2\.1.SDMX Information Model.WebHome]]” to see the diagrammatic notation used to depict this).
12
13 The actual [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Base construct from which the concrete classes inherit depends upon the requirements of the class for:
14
15 [[Annotation>>doc:IMElements.Annotation.WebHome]] – //[[AnnotableArtefact>>doc:IMElements.AnnotableArtefact.WebHome]]//
16 Identification – //[[IdentifiableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.WebHome]]//
17 Naming – //[[NameableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.WebHome]]//
18 Versioning – //[[VersionableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.WebHome]]//
19 Maintenance – //[[MaintainableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.WebHome]]//

33
34 Those classes in the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] metamodel which require annotations inherit from //[[AnnotableArtefact>>doc:IMElements.AnnotableArtefact.WebHome]]//. These are:
35
36 //[[IdentifiableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.WebHome]]
37 [[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]
38 [[Key>>doc:IMElements.AnnotableArtefact.Key.WebHome]]// (and therefore //[[SeriesKey>>doc:IMElements.AnnotableArtefact.Key.SeriesKey.WebHome]]// and //[[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]]//)
39 //[[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]]//
40
41 Those classes in the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] metamodel which require annotations and global identity are derived from //[[IdentifiableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.WebHome]]//. These are:
42
43 //[[NameableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.WebHome]]
44 [[ComponentList>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.WebHome]]
45 [[Component>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.WebHome]]//
46
47 Those classes in the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] metamodel which require annotations, global identity, multilingual [[name>>doc:IMElements.name.WebHome]] and multilingual [[description>>doc:IMElements.description.WebHome]] are derived from //[[NameableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.WebHome]]//. These are:
48
49 //[[VersionableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.WebHome]]
50 [[Item>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.WebHome]]//
51
52 The classes in the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] metamodel which require annotations, global identity, multilingual [[name>>doc:IMElements.name.WebHome]] and multilingual [[description>>doc:IMElements.description.WebHome]], and versioning are derived from //[[VersionableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.WebHome]]//. These are:
53
54 //[[MaintainableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.WebHome]]//
55
56 Abstract classes which represent information that is maintained by [[Maintenance Agencies>>doc:sdmx:Glossary 2\.1.Maintenance agency.WebHome]] all inherit from //[[MaintainableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.WebHome]]//, they also inherit all the features of a //[[VersionableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.WebHome]]//, and are:
57
58 //[[StructureUsage>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.WebHome]]
59 [[Structure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.WebHome]]
60 [[ItemScheme>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.ItemScheme.WebHome]]//
61
62 All the above classes are abstract. The key to understanding the class diagrams presented in this section are the concrete classes that inherit from these abstract classes.
63
64 Those concrete classes in the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] and [[Dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] packages of the metamodel which require to be maintained by Agencies all inherit (via other abstract classes) from //[[MaintainableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.WebHome]]//, these are:
65
66 [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]]
67 [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]
68 The component structures that are lists of lists, inherit directly from //[[Structure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.WebHome]]//. A //[[Structure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.WebHome]]// contains several lists of [[components>>doc:IMElements.components.WebHome]]. The concrete class that inherits from //[[Structure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.WebHome]]// is:
69 [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]
70
71 A [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] contains a list of [[dimensions>>doc:IMElements.dimensions.WebHome]], a list of [[measures>>doc:IMElements.measures.WebHome]] and a list of [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]].
72
73 The concrete classes which inherit from //[[ComponentList>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.WebHome]]// and are subcomponents of the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] are:
74
75 [[DimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.DimensionDescriptor.WebHome]] – content is [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] and [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]]
76 DimensionGroupDescriptor – content is an association to [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]], [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]]
77 [[MeasureDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.MeasureDescriptor.WebHome]] – content is [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]]
78 [[AttributeDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.AttributeDescriptor.WebHome]] – content is [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] and an association to [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]]
79
80 The classes that inherit from //[[Component>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.WebHome]]// are:
81
82 [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]]
83 //[[DimensionComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.WebHome]]// and thereby its sub classes of [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] and [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]]
84 //[[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]// and thereby its sub classes of [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] and [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]]
85
86 The concrete classes identified above are the majority of the classes required to define the metamodel for the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]. The diagrams and explanations in the rest of this section show how these concrete classes are related in order to support the functionality required.

100 A [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] defines the Dimensions, [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]], DataAttributes, and Measures, and associated Representations, that comprise the valid [[structure>>doc:IMElements.structure.WebHome]] of data and related [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] that are contained in a [[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]], which is defined by a [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]]. In addition, a [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] may be related to one [[MetadataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.MetadataStructureDefinition.WebHome]], in order to use the latter’s MetadataAttributes, by relating them to other //Components// within the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], as explained below.
101
102 The [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]] may also have additional [[metadata>>doc:IMElements.metadata.WebHome]] attached that define qualitative information and [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] on the use of the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] such as the subset of Codes used in a [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] (this is covered later in this document – see sections “[[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]” and “Data Provisioning”). Each [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]] has a maximum of one [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] specified which defines the [[structure>>doc:IMElements.structure.WebHome]] of any [[DataSets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] to be reported/disseminated. A [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]] may optionally define which Dimensions it uses, by defining a [[DimensionConstraint>>doc:IMElements.DimensionConstraint.WebHome]] (this is a mandatory requirement if the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] sets its’ [[evolvingStructure>>doc:IMElements.evolvingStructure.WebHome]] property to ‘true’ and is sematically referenced by the [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]]).
103
104 There are two types of [[dimensions>>doc:IMElements.dimensions.WebHome]] each having a common association to [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]]:
105
106 * [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]]
107 * [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]]
108
109 Note that [[DimensionComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.WebHome]] can be any or all its sub classes i.e., [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]], [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]].
110
111 The //[[DimensionComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.WebHome]]//, [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]], [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]] and [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] link to the [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]] that defines its [[name>>doc:IMElements.name.WebHome]] and semantic (/conceptIdentity association to [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]]). The [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]], [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] (but not [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]]) and [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] can optionally have a +conceptRole association with a [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]] that identifies its [[role>>doc:IMElements.role.WebHome]] in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]], or one of the standard pre-defined roles, i.e., those published in "GUIDELINES FOR SDMX CONCEPT ROLES" by the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] SWG. The use of these roles is to enable applications to process the data in a meaningful way (e.g., relating a dimension [[value>>doc:IMElements.value.WebHome]] to a mapping vector). It is expected, beyond the standard roles published by the SWG, that communities (such as the official statistics community) will harmonise such roles within their community so that data can be exchanged and shared in a meaningful way within that community.
112
113 The valid values for a //[[DimensionComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.WebHome]]//, [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]], [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] or [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]], when used in this [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]], are defined by the [[Representation>>doc:IMElements.Representation.WebHome]]. This [[Representation>>doc:IMElements.Representation.WebHome]] is taken from the [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]] definition ([[coreRepresentation>>doc:IMElements.coreRepresentation.WebHome]]) unless it is overridden in this [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] ([[localRepresentation>>doc:IMElements.localRepresentation.WebHome]]) – see Figure 28. Note also that [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]] is constrained to specific FacetValueTypes. Moreover, the Representations of MetadataAttributes are specified in the corresponding [[MetadataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.MetadataStructureDefinition.WebHome]], linked by the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]].
114
115 There will always be a [[DimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.DimensionDescriptor.WebHome]] [[grouping>>doc:IMElements.grouping.WebHome]] that identifies all of the [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] comprising the full key. Together the Dimensions specify the key of an [[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]].
116
117 The //[[DimensionComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.WebHome]]// can optionally be grouped by multiple GroupDimensionDescriptors each of which identifies the group of Dimensions that can form a partial key. The [[GroupDimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.GroupDimensionDescriptor.WebHome]] must be identified ([[GroupDimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.GroupDimensionDescriptor.WebHome]].id) and this is used in the [[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]] of the [[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] to declare which DataAttributes or MetadataAttributes are reported at this group level in the [[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]].
118
119 There can be a maximum of one [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]] specified in the [[DimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.DimensionDescriptor.WebHome]]. The [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]] is used to specify the [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]] used to convey the [[time period>>doc:sdmx:Glossary 2\.1.Time period.WebHome]] of the observation in a [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. The [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]] must contain a valid representation of time and cannot be coded.
120
121 There can be one or more Measures under the [[MeasureDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.MeasureDescriptor.WebHome]]. Measures represent the observable phenomena. Each [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] may have a valid representation, a [[maxOccurs>>doc:IMElements.maxOccurs.WebHome]] [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] limiting the maximum number of values per [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] (which may be set to 'unbounded' for unlimited occurrences), as well as a [[minOccurs>>doc:IMElements.minOccurs.WebHome]] [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]], indicating the minimum required number of values, when the [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] is reported. If [[minOccurs>>doc:IMElements.minOccurs.WebHome]] or [[maxOccurs>>doc:IMElements.maxOccurs.WebHome]] are omitted (they both default to ‘1’), the [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] is considered to take a single [[value>>doc:IMElements.value.WebHome]]; otherwise, it is an array. Moreover, the usage [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] indicates whether a [[Measure>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.Measure.WebHome]] must be reported or not, by the corresponding values: mandatory or optional.
122
123 The [[AttributeDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.AttributeDescriptor.WebHome]] may contain one or more //[[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]//s, i.e., at least one [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] definition or one [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]] reference.
124
125 The [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] defines a characteristic of data that are collected or disseminated and is grouped in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] by a single [[AttributeDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.AttributeDescriptor.WebHome]]. The [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] can be indicated if it must be reported or not, by the corresponding [[value>>doc:IMElements.value.WebHome]] of the usage [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]: i.e., mandatory or optional. The property [[minOccurs>>doc:IMElements.minOccurs.WebHome]] specifies the minimum number of array values to be included when the [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] is reported. Moreover, a [[maxOccurs>>doc:IMElements.maxOccurs.WebHome]] [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] indicates whether the [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] may need to report more than one values, i.e., an array of values. The [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] may play a specific [[role>>doc:IMElements.role.WebHome]] in the [[structure>>doc:IMElements.structure.WebHome]] and this is specified by the +[[role>>doc:IMElements.role.WebHome]] association to the [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]] that identifies its [[role>>doc:IMElements.role.WebHome]].
126
127 The [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]] defines [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] that may be collected or disseminated and is grouped together with [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] under the [[AttributeDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.AttributeDescriptor.WebHome]].
128
129 A [[DataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.DataAttribute.WebHome]] or a [[MetadataAttribute>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.MetadataAttribute.WebHome]] (i.e., an //[[AttributeComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.WebHome]]//) is specified as being +[[relatedTo>>doc:IMElements.relatedTo.WebHome]] an [[AttributeRelationship>>doc:IMElements.AttributeRelationship.WebHome]], which defines the constructs to which the //[[AttributeComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.WebHome]]// is to be reported within a //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//. An //[[AttributeComponent>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.AttributeComponent.WebHome]]// can be specified as being related to one of the following [[artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]]:
130
131 * All data within the [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] (DataflowRelationship) – this is equivalent to attaching an [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] to all data within the [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]].

In the actual //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// as exchanged there must, of course, be a reference to the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] and optionally a [[Dataflow>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.StructureUsage.Dataflow.WebHome]] or a ProvisionAgreement, but the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] is not necessarily exchanged with the data. Therefore, the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] classes are shown in the grey areas, as these are not a part of the //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// when the //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// is exchanged. However, the [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]] in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] can be used by an application to validate the contents of the //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// in terms of the valid content of a //[[KeyValue>>doc:IMElements.KeyValue.WebHome]]// as defined by the [[Representation>>doc:IMElements.Representation.WebHome]] in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]].
267
268 An organisation playing the [[role>>doc:IMElements.role.WebHome]] of [[DataProvider>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Organisation.DataProvider.WebHome]] can be responsible for one or more //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//.
269
270 A //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// is formatted as a [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] specific [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] ([[StructureSpecificDataSet>>doc:IMElements.AnnotableArtefact.DataSet.StructureSpecificDataSet.WebHome]]). The structured [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] is structured according to one specific [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]; hence the latter is required for validation at the syntax level.
271
272 A //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// is a collection of a set of //[[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]]//s that share the same dimensionality, which is specified by a set of unique [[components>>doc:IMElements.components.WebHome]] ([[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]], [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]]) defined in the [[DimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.DimensionDescriptor.WebHome]] of the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]], together with associated //[[AttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.WebHome]]//s that define specific characteristics about the [[artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] to which it is attached – //[[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]]//s, set of Dimensions. It can be structured in terms of a [[SeriesKey>>doc:IMElements.AnnotableArtefact.Key.SeriesKey.WebHome]] to which //[[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]]//s are reported.
273
274 The //[[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]]// can be the [[value>>doc:IMElements.value.WebHome]](s) of the variable(s) being measured for the [[Concept>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Concept.WebHome]] associated to the Measure(s) in the [[MeasureDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.MeasureDescriptor.WebHome]] of the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]. Each //[[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]]// associates one or more //[[ObservationValue>>doc:IMElements.AnnotableArtefact.ObservationValue.WebHome]]//s with a [[KeyValue>>doc:IMElements.KeyValue.WebHome]] (+[[observationDimension>>doc:IMElements.observationDimension.WebHome]]) which is the [[value>>doc:IMElements.value.WebHome]] for the “[[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] at the [[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]] Level”. Any [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] can be specified as being the “[[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] at the [[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]] Level”, and this specification is made at the level of the //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// (i.e., it must be the same [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] for the entire //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//).
275
276 The //[[KeyValue>>doc:IMElements.KeyValue.WebHome]]// is a [[value>>doc:IMElements.value.WebHome]] for one of [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]] or [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] specified in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]. If it is a [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]], it can be coded ([[CodedKeyValue>>doc:IMElements.KeyValue.CodedKeyValue.WebHome]]) or uncoded ([[UncodedKeyValue>>doc:IMElements.KeyValue.UncodedKeyValue.WebHome]]). If it is the [[TimeDimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.TimeDimension.WebHome]] then it is a [[TimeKeyValue>>doc:IMElements.KeyValue.TimeKeyValue.WebHome]]. The actual [[value>>doc:IMElements.value.WebHome]] that the CodedDimensionValue can take must be one of the Codes in the [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] specified as the [[Representation>>doc:IMElements.Representation.WebHome]] of the [[Dimension>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.Component.DimensionComponent.Dimension.WebHome]] in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]].
277
278 An [[ObservationValue>>doc:IMElements.AnnotableArtefact.ObservationValue.WebHome]] can be coded – this is the [[CodedObservation>>doc:IMElements.AnnotableArtefact.ObservationValue.CodedObservation.WebHome]] – or it can be uncoded – this is the UncodedObservation. In the case of uncoded observations, the values may be multilingual – expressed via the [[TextMeasureValue>>doc:IMElements.AnnotableArtefact.ObservationValue.UncodedObservationValue.TextMeasureValue.WebHome]] – or not ([[OtherUncodedMeasureValue>>doc:IMElements.AnnotableArtefact.ObservationValue.UncodedObservationValue.OtherUncodedMeasureValue.WebHome]]).
279
280 The [[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]] is a subunit of the //[[Key>>doc:IMElements.AnnotableArtefact.Key.WebHome]]// that has the same dimensionality as the [[SeriesKey>>doc:IMElements.AnnotableArtefact.Key.SeriesKey.WebHome]] but defines a subset of the KeyValues of the [[SeriesKey>>doc:IMElements.AnnotableArtefact.Key.SeriesKey.WebHome]]. Its sub dimension [[structure>>doc:IMElements.structure.WebHome]] is defined in the [[GroupDimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.GroupDimensionDescriptor.WebHome]] of the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] identified by the same [[id>>doc:IMElements.id.WebHome]] as the [[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]]. The [[id>>doc:IMElements.id.WebHome]] identifies a “[[type>>doc:IMElements.type.WebHome]]” of group and the purpose of the [[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]] is to report one or more //[[AttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.WebHome]]// that are contained at this group level. The [[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]] is present when the [[GroupDimensionDescriptor>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.ComponentList.GroupDimensionDescriptor.WebHome]] is related to the [[GroupRelationship>>doc:IMElements.AttributeRelationship.GroupRelationship.WebHome]] in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]]. There can be many types of groups in a //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//. If the Group is related to the [[DimensionRelationship>>doc:IMElements.AttributeRelationship.DimensionRelationship.WebHome]] in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] then the //[[AttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.WebHome]]// will be reported with the appropriate dimension in the [[SeriesKey>>doc:IMElements.AnnotableArtefact.Key.SeriesKey.WebHome]] or [[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]].
281
282 In this way each of [[SeriesKey>>doc:IMElements.AnnotableArtefact.Key.SeriesKey.WebHome]], [[GroupKey>>doc:IMElements.AnnotableArtefact.Key.GroupKey.WebHome]], and [[Observation>>doc:IMElements.AnnotableArtefact.Observation.WebHome]] can have zero or more //[[AttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.WebHome]]//s that define some [[metadata>>doc:IMElements.metadata.WebHome]] about the object to which it is associated. The //[[AttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.WebHome]]// may be either a //[[DataAttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.DataAttributeValue.WebHome]]// or a //[[MetadataAttributeValue>>doc:IMElements.AnnotableArtefact.AttributeValue.MetadataAttributeValue.WebHome]]//, representing values of DataAttributes defined in the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] or MetadataAttributes of the linked [[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]], respectively. The allowable Concepts and the objects to which these [[metadata>>doc:IMElements.metadata.WebHome]] can be associated (attached) are defined in the [[DataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.DataStructureDefinition.WebHome]] and the linked [[MetadataStructureDefinition>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.Structure.MetadataStructureDefinition.WebHome]].
