| 5 | == 10.1 Introduction == | ||
| 6 | |||
| 7 | |||
| 8 | [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] are used as a way to restrict what data can be reported, or to report what data exists in a given context. There are three types of [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], which serve different purposes | ||
| 9 | |||
| 10 | * Availability [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] | ||
| 11 | * [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] | ||
| 12 | * Reporting [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] | ||
| 13 | |||
| 14 | An Availability [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] defines the data that exists in the context of a data query. | ||
| 15 | |||
| 16 | They form part of the response message from the Availability REST API. Availability [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] are dynamically generated by a system based on the data that exists and the query context. Availability [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] are therefore not Identifiable structures (they have no URN). | ||
| 17 | |||
| 18 | A [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is a property of a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], they are used to fix the [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] that they use in the [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] which they use. [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] enable [[Data Structure Definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] to evolve over time by having new [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] added, without having to undergo a major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change. | ||
| 19 | |||
| 20 | A Reporting [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is used to define the set of allowed and/or disallowed values that can be reported in a data or [[metadata set>>doc:sdmx:Glossary 2\.1.Metadata set.WebHome]]. | ||
| 21 | |||
| 22 | == 10.2 Availability Constraint == | ||
| 23 | |||
| 24 | An Availability [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is not a maintained structure, instead it is generated dynamically as a response to the availability REST API. The purpose of the Availability [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is to define the distinct set of values that have data over 1 or more [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]. Unlike a Data and Metadata [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], which can attach to multiple Constrainable structures (of the same type), an Availability [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can only attach to only one structure. The attachment defines the context of the response (data exists for [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] in the context of). The subset of Constrainable structures the Availability [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can attach to are: | ||
| 25 | |||
| 26 | * [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] | ||
| 27 | * [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] | ||
| 28 | * [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] | ||
| 29 | |||
| 30 | == 10.3 Dimension Constraint == | ||
| 31 | |||
| 32 | A [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is a property of a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]; its purpose is to explicitly list the [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] from the corresponding [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] that are being used by the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]. | ||
| 33 | |||
| 34 | |||
| 35 | [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] were introduced in [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 3.1 and are not required for most [[Dataflows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] where the [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] must always contain the full complement of [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] as defined by the corresponding [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. However, for some complex data collections, which may span long periods and where the full complement of required [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] are not necessarily known at design time, the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] is subject to increasing its Dimensionality over time. In this scenario it is possible to define the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] as an evolving structure, this property tells the user that the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] can have new [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] added without having to undergo a major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change; a [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] at [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] 1.0.0 for example would be able to add a new [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] and move to [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] 1.1.0; a change that would not ordinarily be allowed. A minor [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change on the addition of a new [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] is only possible if the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] defines itself as an evolving structure. This is a new property of the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] introduced in [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] 3.1 to satisfy this use case. The evolving structure property is either true or false, defaulting to false if not specified. Setting the evolving structure property to true requires a major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change, and therefore can only be introduced on an x.0.0 release (e.g. 1.0.0). The evolving structure property can be set to false to indicate that there will be no additional [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] added to the Data Structure under the same major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] number; setting the evolving structure property to false does not require require a major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change on the Data Structure. | ||
| 36 | |||
| 37 | When a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] references a [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], late binding on the minor release, and the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] has the evolving structure property set to true, then the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] must contain a [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] to protect its Dimensionality from changing over time without a [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change. | ||
| 38 | |||
| 39 | The [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] provides the explicit list of [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] that the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] uses from the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] that it references. This enables the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] to evolve over time without breaking the compatibility of [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] against the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]. | ||
| 40 | |||
| 41 | __**Rules for a Dimension Constraint**__ | ||
| 42 | |||
| 43 | * A [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] must contain a [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] if the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] which it uses states that it is an evolving structure and the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] is late binding on the minor release (latest minor release of a given major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]], e.g. 1.0+.0) | ||
| 44 | * The [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can only include [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] from the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] that is referenced by the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]. | ||
| 45 | * A [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can only be changed if the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] undergoes a major [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] change | ||
| 46 | * [[Datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] reported against the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] must only contain reported values for the [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] specified in the [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]. | ||
| 47 | * When exporting data for the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], the [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] should only include the [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] specified by the [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]. | ||
| 48 | * When exporting data for the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] the [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] must contain the full set of [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] as specified by the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. The tilde ‘’ character is used to represent a value which is not present due to the [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] not being included in the corresponding [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]. | ||
| 49 | |||
| 50 | __**Example Datasets with Evolving Structures**__ | ||
| 51 | |||
| 52 | A [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] is built against a [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. The [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] contains data for two [[Dataflows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]. [[Dataflows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] ‘DF_POP’ uses a [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] which fixes its [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] to FREQ and REF_AREA. [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] ‘DF_POP_SA’ does not reference a [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], and as such includes all [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] as specified by the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. | ||
| 53 | |||
| 54 | The resulting [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] contains values ‘’ for both the [[SEX>>doc:sdmx:Glossary 2\.1.Sex.WebHome]] and [[AGE>>doc:sdmx:Glossary 2\.1.Age.WebHome]] [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] for the [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] related to DF_POP. | ||

| 62 | == 10.4 Reporting Constraints == | ||
| 63 | |||
| 64 | A Reporting [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is a [[Maintainable Artefact>>doc:sdmx:Glossary 2\.1.Maintainable artefact.WebHome]] which restricts the values that can be reported in a [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] or [[metadata set>>doc:sdmx:Glossary 2\.1.Metadata set.WebHome]] based on one or more inclusion or exclusion rules. | ||
| 65 | |||
| 66 | A reporting [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is one of the following concrete types: | ||
| 67 | |||
| 68 | * Data [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] | ||
| 69 | * Metadata [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] | ||
| 70 | |||
| 71 | === 10.4.1 Data Constraint === | ||
| 72 | |||
| 73 | A Data [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is used to add additional restrictions to the allowable values reported in a [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. Data [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can be applied to the follow structures which are collectively known as Constrainable structures: | ||
| 74 | |||
| 75 | * [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] | ||
| 76 | * [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] | ||
| 77 | * [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] | ||
| 78 | * [[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]] | ||
| 79 | |||
| 80 | **Note** regardless of the Constrainable structure, the restricted values relate to the allowable content for the [[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] of the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] to which the constrained object relates. | ||
| 81 | |||
| 82 | === 10.4.2 Metadata Constraint === | ||
| 83 | |||
| 84 | A Metadata [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is used to add additional restrictions to the allowable values reported in a metadataset. Metadata [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can be applied to the follow structures which are collectively known as Constrainable structures: | ||
| 85 | |||
| 86 | * [[Metadata Structure Definition>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] | ||
| 87 | * [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] | ||
| 88 | * Metadata [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] | ||
| 89 | * Metadata Provider | ||
| 90 | |||
| 91 | **Note** regardless of the Constrainable structure, the restricted values relate to the allowable content for the [[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] of the [[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] to which the constrained object relates. | ||
| 92 | |||
| 93 | === 10.4.3 Scope of a Constraint === | ||
| 94 | |||
| 95 | A [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is used specify the content of a data or metadata source in terms of the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] values or the keys. | ||
| 96 | |||
| 97 | In terms of data the [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] are: | ||
| 98 | |||
| 99 | * [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] | ||
| 100 | * Time [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] | ||
| 101 | * Data [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] | ||
| 102 | * [[Measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] | ||
| 103 | * Metadata [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] | ||
| 104 | * DataKeySets: the keys are the content of the KeyDescriptor – i.e., the [[series keys>>doc:sdmx:Glossary 2\.1.Series key.WebHome]] composed, for each key, by a value for each [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]. | ||
| 105 | |||
| 106 | In terms of [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] the [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] are: | ||
| 107 | |||
| 108 | * Metadata [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] | ||
| 109 | |||
| 110 | For a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] based on a [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can reference one or more of: | ||
| 111 | |||
| 112 | * [[Data Structure Definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] | ||
| 113 | * [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] | ||
| 114 | * [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] | ||
| 115 | * [[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]] | ||
| 116 | |||
| 117 | For a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] based on an [[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can reference one or more of: | ||
| 118 | |||
| 119 | * [[Metadata Structure Definition>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] | ||
| 120 | * [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] | ||
| 121 | * Metadata [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] | ||
| 122 | * Metadata Provider | ||
| 123 | * [[Metadata Set>>doc:sdmx:Glossary 2\.1.Metadata set.WebHome]] | ||
| 124 | |||
| 125 | Furthermore, there can be more than one [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified for a specific object e.g., more than one [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] for a specific [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. | ||
| 126 | |||
| 127 | In view of the flexibility of [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] attachment, clear rules on their usage are required. These are elaborated below. | ||
| 128 | |||
| 129 | === 10.4.4 Multiple Constraints === | ||
| 130 | |||
| 131 | There can be many [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] for any Constrainable [[Artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] (e.g., [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]), subject to the following restrictions: | ||
| 132 | |||
| 133 | ==== 10.4.4.1 Cube Region ==== | ||
| 134 | |||
| 135 | A [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] can contain multiple [[Member Selections>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] (e.g., [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]). | ||
| 136 | |||
| 137 | * A specific [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] (e.g., [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] FREQ) can only be contained in one Cube Region for any one attached object (e.g., a specific [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] or specific [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]). | ||
| 138 | * [[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] values within a [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] may define a validity period. Otherwise, the value is valid for the whole validity of the Cube Region. | ||
| 139 | * For partial reference resolution purposes (as per the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] REST API), the latest non-draft [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] must be considered. | ||
| 140 | * A [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] may include wildcarding of values (using character ‘%’ to represent zero or more occurrences of any character), as well as cascading through hierarchic structures (e.g., parents in [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]]), or localised values (e.g., text for English only). Lack of locale means any [[language>>doc:sdmx:Glossary 2\.1.Language.WebHome]] may match. Cascading values are mutual exclusive to localised values, as the former refer to coded values, while the latter refer to uncoded values. | ||
| 141 | * Any values included in a [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] for [[Components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] with an array data type (i.e., [[Measures>>doc:sdmx:Glossary 2\.1.Measure.WebHome]], [[Attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] or Metadata [[Attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]), will be applied as single values and will not be assessed combined with other values to match all possible array values. For example, including the [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] ‘A’ for an [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will allow any instance of the [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] that includes ‘A’, like [‘A’, ‘B’] or [‘A’, ‘C’, ‘D’]. Similarly, if [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] ‘A’ was excluded, all those arrays of values would also be excluded. | ||
| 142 | |||
| 143 | ==== 10.4.4.2 Key Set ==== | ||
| 144 | |||
| 145 | Key Sets will be processed in the order they appear in the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] and wildcards can be used (e.g., any key position not reference explicitly is deemed to be "all values"). | ||
| 146 | |||
| 147 | As the Key Sets can be "included" or "excluded" it is recommended that Key Sets with wildcards are declared before KeySets with specific [[series keys>>doc:sdmx:Glossary 2\.1.Series key.WebHome]]. This will minimize the risk that keys are inadvertently included or excluded. | ||
| 148 | |||
| 149 | In addition, [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]], [[Measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] and Metadata [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] may accompany KeySets, in order to specify the allowed values per Key. Those are expressed following the rules for Cube Regions, as explained above. | ||
| 150 | |||
| 151 | Finally, a validity period may be specified per Key. | ||
| 152 | |||
| 153 | === 10.4.4 Versioning === | ||
| 154 | |||
| 155 | When Data and Metadata [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] are versioned, the latest [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] of the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is used to generate the reporting restriction rules; all previous [[versions>>doc:sdmx:Glossary 2\.1.Version.WebHome]] are for historical information only. | ||
| 156 | |||
| 157 | If restrictions are applicable to certain periods in time, the validFrom and validTo properties can be set on the specific values. This allows [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] to evolve over time, increasing their [[version>>doc:sdmx:Glossary 2\.1.Version.WebHome]] number as they do so, whilst being able to maintain a complete set of reporting restrictions for current and past [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. | ||
| 158 | |||
| 159 | Example: | ||
| 160 | |||
| 161 | Data Constraint 1.0.0 | ||
| 162 | |||
| 163 | (% style="width:573.294px" %) | ||
| 164 | |(% style="width:108px" %)Component|(% style="width:127px" %)Valid Value|(% style="width:150px" %)Valid from|(% style="width:185px" %)Valid to | ||

| 167 | |(% style="width:127px" %)DE|(% style="width:150px" %) |(% style="width:185px" %) | ||
| 168 | |||
| 169 | Data Constraint 1.1.0 | ||
| 170 | |||
| 171 | (% style="width:576.294px" %) | ||
| 172 | |(% style="width:110px" %)Component|(% style="width:129px" %)Valid Value|(% style="width:145px" %)Valid from|(% style="width:189px" %)Valid to | ||
| 173 | |(% rowspan="3" style="width:110px" %)COUNTRY|(% style="width:129px" %)UK|(% style="width:145px" %) |(% style="width:189px" %) | ||
| 174 | |(% style="width:129px" %)FR|(% style="width:145px" %) |(% style="width:189px" %)2012 | ||
| 175 | |(% style="width:129px" %)DE|(% style="width:145px" %) |(% style="width:189px" %) | ||
| 176 | |||
| 177 | When both [[versions>>doc:sdmx:Glossary 2\.1.Version.WebHome]] of the Data [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] are in a system, an [[observation value>>doc:sdmx:Glossary 2\.1.Observation value.WebHome]] reported against COUNTRY FR for [[time period>>doc:sdmx:Glossary 2\.1.Time period.WebHome]] 2013 would be deemed invalid as the 1.1.0 rule would be applied. | ||
| 178 | |||
| 179 | === 10.4.6 Inheritance === | ||
| 180 | |||
| 181 | ==== 10.4.6.1 Attachment levels of a Constraint ==== | ||
| 182 | |||
| 183 | There are three [[levels>>doc:sdmx:Glossary 2\.1.Level.WebHome]] of [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] attachment for which these inheritance rules apply: | ||
| 184 | |||
| 185 | * [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]/[[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] – top [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] | ||
| 186 | ** [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]/[[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] – second [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] | ||
| 187 | *** [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] – third [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] | ||
| 188 | |||
| 189 | It is not necessary for a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] to be attached to a higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]]. e.g., it is valid to have a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] for a [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] where there are no [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] attached the relevant [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] or [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. | ||
| 190 | |||
| 191 | ==== 10.4.6.2 Cascade rules for processing Constraints ==== | ||
| 192 | |||
| 193 | The processing of the [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] on either [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]/[[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] or [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] must take into account the [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] declared at higher [[levels>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. The rules for the lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] (attached to [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]/ [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] and [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]]) are detailed below. | ||
| 194 | |||
| 195 | Note that there can be a situation where a [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is specified at a lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] before a [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is specified at a higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. Therefore, it is possible that a higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] makes a lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] invalid. [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] makes no rules on how such a conflict should be handled when processing the [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] for attachment. However, the cascade rules on evaluating [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] for usage are clear – the higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] takes precedence in any conflicts that result in a less restrictive specification at the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. | ||
| 196 | |||
| 197 | ==== 10.4.6.3 Cube Region ==== | ||
| 198 | |||
| 199 | It is not necessary to have a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] on the higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] (e.g., [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] referenced by the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]), but if there is such a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at the higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]](s) then: | ||
| 200 | |||
| 201 | * The lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] cannot be less restrictive than the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified for the same [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] (e.g. [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]) at the next higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]], which constrains that [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]]. For example, if the [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] FREQ is constrained to A, Q in a [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], then the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] or [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] cannot be A, Q, M or even just M – it can only further constrain A, Q. | ||
| 202 | * The [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] for any one [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] further constrains the content for the same [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] at the higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]](s). | ||
| 203 | * Any [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]], which is not referenced in a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], is deemed to be constrained according to the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified at the next higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] which [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] that [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]]. | ||
| 204 | * If there is a conflict when resolving the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] in terms of a lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] being less restrictive than a higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], then the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at the higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] is used. | ||
| 205 | |||
| 206 | Note that it is possible for a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at a higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] to constrain, say, four [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] in a single [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], and a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at a lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] to constrain the same four in two, three, or four [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]. | ||
| 207 | |||
| 208 | ==== 10.4.6.4 Key Set ==== | ||
| 209 | |||
| 210 | It is not necessary to have a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] on the higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] (e.g., [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] referenced by the [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]), but if there is such a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at the higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]](s) then: | ||
| 211 | |||
| 212 | * The lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] cannot be less restrictive than the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified at the higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. | ||
| 213 | * The [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] for any one [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]] further constrains the keys specified at the higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]](s). | ||
| 214 | * Any [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]], which is not referenced in a [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], is deemed to be constrained according to the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified at the next higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] which [[constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] that [[Member Selection>>doc:sdmx:Glossary 2\.1.Member selection.WebHome]]. | ||
| 215 | * If there is a conflict when resolving the keys in the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] at two [[levels>>doc:sdmx:Glossary 2\.1.Level.WebHome]], in terms of a lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] being less restrictive than a higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], then the offending keys specified at the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] are not deemed part of the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]. | ||
| 216 | |||
| 217 | Note that a Key in a Key Set can have wildcarded [[Components>>doc:sdmx:Glossary 2\.1.Component.WebHome]]. For instance, the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] may simply constrain the [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] FREQ to "A", and all keys where the FREQ="A" are therefore valid. | ||
| 218 | |||
| 219 | The following logic explains how the inheritance mechanism works. Note that this is conceptual logic and actual systems may differ in the way this is implemented. | ||
| 220 | |||
| 221 | 1. Determine all possible keys that are valid at the higher [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. | ||
| 222 | 1. These keys are deemed to be inherited by the lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] constrained object, subject to the [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified at the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. | ||
| 223 | 1. Determine all possible keys that are possible using the [[Constraints>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] specified at the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]]. | ||
| 224 | 1. At the lower [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] inherit all keys that match with the higher-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]. | ||
| 225 | 1. If there are keys in the lower-[[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] that are not inherited then the key is invalid (i.e., it is less restrictive). | ||

| 228 | |||
| 229 | ==== 10.4.7.1 Data Constraint and Cascading ==== | ||
| 230 | |||
| 231 | The following scenario is used. | ||
| 232 | |||
| 233 | A [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] contains the following [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]: | ||

| 239 | |||
| 240 | In the [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], common [[code lists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] are used and the requirement is to restrict these at various [[levels>>doc:sdmx:Glossary 2\.1.Level.WebHome]] to specify the actual [[code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] that are valid for the object to which the [[Constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] is attached. | ||

| 303 | |||
| 304 | Let’s assume a [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] with the following [[Components>>doc:sdmx:Glossary 2\.1.Component.WebHome]]: | ||

| 392 | The problem with this approach is that according to the business rule for (% style="color:#e74c3c" %)Constraints(%%), only one should be specified per [[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]]. Thus, if a software would perform some conflict resolution would end up with empty sets for FREQ and OBS_STATUS (as they do not share any values). | ||
| 393 | |||
| 394 | Nevertheless, there is a much easier approach to that; this is the cascading mechanism of (% style="color:#e74c3c" %)Constraints(%%) (as shown in 10.4.7.1). Hence, these rules would be expressed into two (% style="color:#e74c3c" %)levels(%%) of (% style="color:#e74c3c" %)Constraints(%%), e.g., [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] and [[Dataflows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]: | ||
