5 == 8.1 Introduction ==
6
7 In this (% style="color:#e74c3c" %)version(%%) of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] the (% style="color:#e74c3c" %)Constraints(%%) is a [[Maintainable Artefact>>doc:sdmx:Glossary.Maintainable artefact.WebHome]] can be associated to one or more of:
8
9 * Data Structure Definition
10 * [[Metadata Structure Definition>>doc:sdmx:Glossary.Metadata structure definition.WebHome]]
11 * [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]
12 * [[Metadataflow>>doc:sdmx:Glossary.Metadataflow.WebHome]]
13 * [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]]
14 * [[Data Provider>>doc:sdmx:Glossary.Data provider.WebHome]] (this is restricted to a [[Release Calendar>>doc:sdmx:Glossary.Release policy - release calendar.WebHome]] (% style="color:#e74c3c" %)Constraint(%%))
15 * Simple or Queryable Datasources
16
17 Note that regardless of the artifact to which the (% style="color:#e74c3c" %)Constraint(%%) is associated, it is constraining the contents of [[code lists>>doc:sdmx:Glossary.Code list.WebHome]] in the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] to which the constrained object is related. This does not apply, of course, to a [[Data Provider>>doc:sdmx:Glossary.Data provider.WebHome]] as the [[Data Provider>>doc:sdmx:Glossary.Data provider.WebHome]] can be associated, via the [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]], to many DSDs. Hence the reason for the restriction on the type of (% style="color:#e74c3c" %)Constraint(%%) that can be attached to a [[Data Provider>>doc:sdmx:Glossary.Data provider.WebHome]].
18
19 == 8.2 Types of Constraint ==
20
21 The (% style="color:#e74c3c" %)Constraint(%%) can be of one of two types:
22
23 * Content (% style="color:#e74c3c" %)constraint
24 * Attachable (% style="color:#e74c3c" %)constraint
25
26 The attachable (% style="color:#e74c3c" %)constraint(%%) is used to define “cube slices” which identify sub sets of data in terms of [[series keys>>doc:sdmx:Glossary.Series key.WebHome]] or [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] values. The purpose of this is to enable metadata to be attached to the (% style="color:#e74c3c" %)constraint(%%), and thereby to the cube slices defined in the (% style="color:#e74c3c" %)Constraint(%%). The metadata can be attached via the “[[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]]” mechanism – [[MSD>>doc:sdmx:Glossary.Metadata structure definition.WebHome]] and [[Metadata Set>>doc:sdmx:Glossary.Metadata set.WebHome]] – or via a Group in the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]]. Below is snippet of the schema for a [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] that shows the constructs that enable the (% style="color:#e74c3c" %)Constraint(%%) to referenced from a Group in a [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]].

31
32 For the Content (% style="color:#e74c3c" %)Constraint(%%) specific “inheritance” rules apply and these are detailed below.
33
34 == 8.3 Rules for a Content Constraint ==
35
36 === 8.3.1 Scope of a Content Constraint ===
37
38 A Content (% style="color:#e74c3c" %)Constraint(%%) is used specify the content of a data or metadata source in terms of the [[component>>doc:sdmx:Glossary.Component.WebHome]] values or the keys.
39
40 In terms of data the [[components>>doc:sdmx:Glossary.Component.WebHome]] are:
41
42 * [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]
43 * [[Measure>>doc:sdmx:Glossary.Measure.WebHome]] [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]
44 * Time [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]
45 * Data [[Attribute>>doc:sdmx:Glossary.Attribute.WebHome]]
46 * Primary [[Measure>>doc:sdmx:Glossary.Measure.WebHome]]
47
48 And the keys are the content of the KeyDescriptor – i.e. the [[series keys>>doc:sdmx:Glossary.Series key.WebHome]] composed, for each key, by a value for each [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] and [[Measure>>doc:sdmx:Glossary.Measure.WebHome]] [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]
49
50 In terms of [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]] the [[components>>doc:sdmx:Glossary.Component.WebHome]] are:
51
52 * Target Object which is one of:
53 ** Key Descriptor Values o [[Data Set>>doc:sdmx:Glossary.Data set.WebHome]] o Report Period
54 ** IdentifiableObject
55 * Metadata [[Attribute>>doc:sdmx:Glossary.Attribute.WebHome]]
56
57 The “key” is therefore the combination of the Target Objects that are defined for the Metadata Target.
58
59 For a (% style="color:#e74c3c" %)Constraint(%%) based on a [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] the Content (% style="color:#e74c3c" %)Constraint(%%) can reference one or more of:
60
61 * Data Structure Definition
62 * [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]
63 * [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]]
64
65 For a (% style="color:#e74c3c" %)Constraint(%%) based on an [[MSD>>doc:sdmx:Glossary.Metadata structure definition.WebHome]] the Content (% style="color:#e74c3c" %)Constraint(%%) can reference one or more of:
66
67 * [[Metadata Structure Definition>>doc:sdmx:Glossary.Metadata structure definition.WebHome]]
68 * [[Metadataflow>>doc:sdmx:Glossary.Metadataflow.WebHome]]
69 * [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]]
70
71 Furthermore, there can be more than one Content (% style="color:#e74c3c" %)Constraint(%%) specified for a specific object e.g. more than one (% style="color:#e74c3c" %)Constraint(%%) for a specific [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]].
72
73 In view of the flexibility of (% style="color:#e74c3c" %)constraints(%%) attachment, clear rules on their usage are required. These are elaborated below.
74
75 === 8.3.2 Multiple Content Constraints ===
76
77 There can be many Content (% style="color:#e74c3c" %)Constraints(%%) for any Constrainable [[Artefact>>doc:sdmx:Glossary.Artefact.WebHome]] (e.g. [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]]), subject to the following restrictions:
78
79 ==== 8.3.2.1 Cube Region ====
80
81 1. The (% style="color:#e74c3c" %)constraint(%%) can contain multiple [[Member Selections>>doc:sdmx:Glossary.Member selection.WebHome]] (e.g. [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]) but:
82 1. A specific [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] (e.g. [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] FREQ) can only be contained in one Content (% style="color:#e74c3c" %)Constraint(%%) for any one attached object (e.g. a specific [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] or specific [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]])
83
84 ==== 8.3.2.2 Key Set ====
85
86 Key Sets will be processed in the order they appear in the (% style="color:#e74c3c" %)Constraint(%%) and wildcards can be used (e.g. any key position not reference explicitly is deemed to be “all values”). 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.Series key.WebHome]]. This will minimize the risk that keys are inadvertently included or excluded.
87
88 === 8.3.3 Inheritance of a Content Constraint ===
89
90 ==== 8.3.3.1 Attachment levels of a Content Constraint ====
91
92 There are three (% style="color:#e74c3c" %)levels(%%) of (% style="color:#e74c3c" %)constraint(%%) attachment for which these inheritance rules apply:
93
94 * [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]]/[[MSD>>doc:sdmx:Glossary.Metadata structure definition.WebHome]] – top (% style="color:#e74c3c" %)level
95 ** [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]/[[Metadataflow>>doc:sdmx:Glossary.Metadataflow.WebHome]] – second (% style="color:#e74c3c" %)level
96 *** [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] – third (% style="color:#e74c3c" %)level
97
98 Note that these rules do not apply to the Simple Datasoucre or Queryable Datasource: the Content (% style="color:#e74c3c" %)Constraint(%%)(s) attached to these [[artefacts>>doc:sdmx:Glossary.Artefact.WebHome]] are resolved for this [[artefact>>doc:sdmx:Glossary.Artefact.WebHome]] only and do not take into account (% style="color:#e74c3c" %)Constraints(%%) attached to other [[artefacts>>doc:sdmx:Glossary.Artefact.WebHome]] (e.g. [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]]. [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]], [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]]).
99
100 It is not necessary for a Content (% style="color:#e74c3c" %)Constraint(%%) to be attached to higher (% style="color:#e74c3c" %)level(%%) artifact. e.g. it is valid to have a Content (% style="color:#e74c3c" %)Constraint(%%) for a [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] where there are no (% style="color:#e74c3c" %)constraints(%%) attached the relevant [[dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] or [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]].
101
102 ==== 8.3.3.2 Cascade rules for processing Constraints ====
103
104 The processing of the (% style="color:#e74c3c" %)constraints(%%) on either [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]/[[Metadataflow>>doc:sdmx:Glossary.Metadataflow.WebHome]] or [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] must take into account the (% style="color:#e74c3c" %)constraints(%%) declared at higher (% style="color:#e74c3c" %)levels(%%). The rules for the lower (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraints(%%) (attached to [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]/ [[Metadataflow>>doc:sdmx:Glossary.Metadataflow.WebHome]] and [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]]) are detailed below.
105
106 Note that there can be a situation where a (% style="color:#e74c3c" %)constraint(%%) is specified at a lower (% style="color:#e74c3c" %)level(%%) before a (% style="color:#e74c3c" %)constraint(%%) is specified at a higher (% style="color:#e74c3c" %)level(%%). Therefore, it is possible that a higher (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) makes a lower (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) invalid. [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] makes no rules on how such a conflict should be handled when processing the (% style="color:#e74c3c" %)constraint(%%) for attachment. However, the cascade rules on evaluating (% style="color:#e74c3c" %)constraints(%%) for usage are clear - the higher (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) takes precedence in any conflicts that result in a less restrictive specification at the lower (% style="color:#e74c3c" %)level(%%).
107
108 ==== 8.3.3.3 Cube Region ====
109
110 1. It is not necessary to have a (% style="color:#e74c3c" %)constraint(%%) on the higher (% style="color:#e74c3c" %)level(%%) artifact (e.g. [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] referenced by the [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]) but if there is such a (% style="color:#e74c3c" %)constraint(%%) at the higher (% style="color:#e74c3c" %)level(%%)(s) then:
111 a. The lower (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) cannot be less restrictive than the (% style="color:#e74c3c" %)constraint(%%) specified for the same [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] (e.g. [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]) at the next higher (% style="color:#e74c3c" %)level(%%) which (% style="color:#e74c3c" %)constraints(%%) that [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] (e.g. if the [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] FREQ is constrained to A, Q in a [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] then the (% style="color:#e74c3c" %)constraint(%%) at the [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] or [[Provision Agreement>>doc:sdmx:Glossary.Provision agreement.WebHome]] cannot be A, Q, M or even just M – it can only further constrain A,Q).
112 b. The (% style="color:#e74c3c" %)constraint(%%) at the lower (% style="color:#e74c3c" %)level(%%) for any one [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] further constrains the content for the same [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] at the higher (% style="color:#e74c3c" %)level(%%)(s).
113 1. Any [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] which is not referenced in a Content (% style="color:#e74c3c" %)Constraint(%%) is deemed to be constrained according to the Content (% style="color:#e74c3c" %)Constraint(%%) specified at the next higher (% style="color:#e74c3c" %)level(%%) which (% style="color:#e74c3c" %)constraints(%%) that [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]].
114 1. If there is a conflict when resolving the (% style="color:#e74c3c" %)constraint(%%) in terms of a lower-(% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) being less restrictive than a higher-(% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) then the (% style="color:#e74c3c" %)constraint(%%) at the higher-(% style="color:#e74c3c" %)level(%%) is used.
115
116 Note that it is possible for a Content (% style="color:#e74c3c" %)Constraint(%%) at a higher (% style="color:#e74c3c" %)level(%%) to constrain, say, four [[Dimensions>>doc:sdmx:Glossary.Dimension.WebHome]] in a single (% style="color:#e74c3c" %)constraint(%%), and a Content (% style="color:#e74c3c" %)Constraint(%%) at a lower (% style="color:#e74c3c" %)level(%%) to constrain the same four in two, three, or four Content (% style="color:#e74c3c" %)Constraints(%%).
117
118 ==== 8.3.3.4 Key Set ====
119
120 1. It is not necessary to have a (% style="color:#e74c3c" %)constraint(%%) on the higher (% style="color:#e74c3c" %)level(%%) [[artefact>>doc:sdmx:Glossary.Artefact.WebHome]] (e.g. [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] referenced by the [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]]) but if there is such a (% style="color:#e74c3c" %)constraint(%%) at the higher (% style="color:#e74c3c" %)level(%%)(s) then:
121 a. The lower (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) cannot be less restrictive than the (% style="color:#e74c3c" %)constraint(%%) specified at the higher (% style="color:#e74c3c" %)level(%%).
122 b. The (% style="color:#e74c3c" %)constraint(%%) at the lower (% style="color:#e74c3c" %)level(%%) for any one [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] further constrains the keys specified at the higher (% style="color:#e74c3c" %)level(%%)(s).
123 1. Any [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]] which is not referenced in a Content (% style="color:#e74c3c" %)Constraint(%%) is deemed to be constrained according to the Content (% style="color:#e74c3c" %)Constraint(%%) specified at the next higher (% style="color:#e74c3c" %)level(%%) which (% style="color:#e74c3c" %)constraints(%%) that [[Member Selection>>doc:sdmx:Glossary.Member selection.WebHome]].
124 1. If there is a conflict when resolving the keys in the (% style="color:#e74c3c" %)constraint(%%) at two (% style="color:#e74c3c" %)levels(%%), in terms of a lower-(% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) being less restrictive than a higher-(% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%), then the offending keys specified at the lower (% style="color:#e74c3c" %)level(%%) are not deemed part of the (% style="color:#e74c3c" %)constraint(%%).
125
126 Note that a Key in a Key Set can have wildcarded [[Components>>doc:sdmx:Glossary.Component.WebHome]]. For instance the (% style="color:#e74c3c" %)constraint(%%) may simply constrain the [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] FREQ to “A”, and all keys where the FREQ=A are therefore valid.
127
128 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.
129
130 1. Determine all possible keys that are valid at the higher (% style="color:#e74c3c" %)level(%%).
131 1. These keys are deemed to be inherited by the lower (% style="color:#e74c3c" %)level(%%) constrained object, subject to the (% style="color:#e74c3c" %)constraints(%%) specified at the lower (% style="color:#e74c3c" %)level(%%).
132 1. Determine all possible keys that are possible using the (% style="color:#e74c3c" %)constraints(%%) specified at the lower (% style="color:#e74c3c" %)level(%%).
133 1. At the lower (% style="color:#e74c3c" %)level(%%) inherit all keys that match with the higher (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%).
134 1. If there are keys in the lower (% style="color:#e74c3c" %)level(%%) (% style="color:#e74c3c" %)constraint(%%) that are not inherited then the key is invalid (i.e. it is less restrictive).
135
136 === 8.3.4 Constraints Examples ===
137
138 The following scenario is used.
139
140 __DSD__
141
142 This contains the following [[Dimensions>>doc:sdmx:Glossary.Dimension.WebHome]]:
143
144 * GEO – Geography
145 * SEX – Sex
146 * [[AGE>>doc:sdmx:Glossary.Age.WebHome]] – [[Age>>doc:sdmx:Glossary.Age.WebHome]]
147 * CAS – Current Activity Status
148
149 In the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] common [[code lists>>doc:sdmx:Glossary.Code list.WebHome]] are used and the requirement is to restrict these at various (% style="color:#e74c3c" %)levels(%%) to specify the actual [[code>>doc:sdmx:Glossary.Code.WebHome]] that are valid for the object to which the Content (% style="color:#e74c3c" %)Constraint(%%) is attached.

161 **Notes:**
162
163 1. [[AGE>>doc:sdmx:Glossary.Age.WebHome]] is constrained for the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] and is further restricted for the [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] CENSUS_CUBE1.
164 1. The same (% style="color:#e74c3c" %)Constraint(%%) applies to both Provision Agreements.

171
172 __Dataflow CENSUS_CUBE1__
173
174 1. Constrained by restricting the [[code list>>doc:sdmx:Glossary.Code list.WebHome]] for the [[AGE>>doc:sdmx:Glossary.Age.WebHome]] [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] to [[codes>>doc:sdmx:Glossary.Code.WebHome]] 002 and 003(note that this is a more restrictive (% style="color:#e74c3c" %)constraint(%%) than that declared for the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]] which specifies all [[codes>>doc:sdmx:Glossary.Code.WebHome]] except [[code>>doc:sdmx:Glossary.Code.WebHome]] 001).
175 1. Restricts the CAS [[codes>>doc:sdmx:Glossary.Code.WebHome]] to 003 and 004.
176
177 __Dataflow CENSUS_CUBE2__
178
179 1. Restricts the [[code list>>doc:sdmx:Glossary.Code list.WebHome]] for the CAS [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] to [[codes>>doc:sdmx:Glossary.Code.WebHome]] TOT and NAP.
180 1. Inherits the [[AGE>>doc:sdmx:Glossary.Age.WebHome]] (% style="color:#e74c3c" %)constraint(%%) applied at the (% style="color:#e74c3c" %)level(%%) of the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]].
181
182 __Provision Agreements CENSUS_CUBE1_IT__
183
184 1. Restricts the [[codes>>doc:sdmx:Glossary.Code.WebHome]] for the GEO [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] to IT and its children.
185 1. Inherits the (% style="color:#e74c3c" %)constraints(%%) from [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] CENSUS_CUBE1 for the [[AGE>>doc:sdmx:Glossary.Age.WebHome]] and CAS [[Dimensions>>doc:sdmx:Glossary.Dimension.WebHome]].
186
187 __Provision Agreements CENSUS_CUBE2_IT__
188
189 1. Restricts the [[codes>>doc:sdmx:Glossary.Code.WebHome]] for the GEO [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] to IT and its children.
190 1. Inherits the (% style="color:#e74c3c" %)constraints(%%) from [[Dataflow>>doc:sdmx:Glossary.Dataflow.WebHome]] CENSUS_CUBE2 for the CAS [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]].
191 1. Inherits the [[AGE>>doc:sdmx:Glossary.Age.WebHome]] (% style="color:#e74c3c" %)constraint(%%) applied at the (% style="color:#e74c3c" %)level(%%) of the [[DSD>>doc:sdmx:Glossary.Data structure definition.WebHome]].
