An EpochMap and DatePatternMap both provide the ability to map source to target date formats. The EpochMap describes the source date as the number of epochs since a point in time, where the duration of each epoch is defined, e.g., number of milliseconds since 1970. The DatePatternMap describes the source date as a pattern for example MM-YYYY, accompanied by the appropriate locale. 42 42 ... ... @@ -44,61 +44,59 @@ 44 44 45 45 If the Frequency Identifier aligns with standard SDMX frequencies the output date format can be derived using standard SDMX date formatting (e.g., A=YYYY, Q=YYYY-Qn). If the SDMX standard formatting is not desired or if the frequency Id is not a standard SDMX frequency Code, the FrequencyFormatMapping can be used to describe the relationship between the frequency Id and the output date format, e.g., A01=YYYY. 46 46 47 -==== =9.1.4.2 Definitions =====47 +==== 9.1.4.2 Definitions ==== 48 48 49 -|**Class**|**Feature**|**Description** 50 -|StructureMap|((( 49 +(% style="width:974.835px" %) 50 +|**Class**|(% style="width:197px" %)**Feature**|(% style="width:568px" %)**Description** 51 +|StructureMap|(% style="width:197px" %)((( 51 51 Inherits from 52 52 //MaintainableArtefact// 53 -)))|Links a source and target structure where there is a semantic equivalence between the source and the target structures. 54 -| |+sourceStructure|Association to the source Data Structure. 55 -| |+targetStructure|Association to the target Data Structure 56 -| |+sourceStructureUsage|Association to the source Dataflow. 57 -| |+targetStructureUsage|Association to the target Dataflow. 58 -|ComponentMap|((( 54 +)))|(% style="width:568px" %)Links a source and target structure where there is a semantic equivalence between the source and the target structures. 55 +| |(% style="width:197px" %)+sourceStructure|(% style="width:568px" %)Association to the source Data Structure. 56 +| |(% style="width:197px" %)+targetStructure|(% style="width:568px" %)Association to the target Data Structure 57 +| |(% style="width:197px" %)+sourceStructureUsage|(% style="width:568px" %)Association to the source Dataflow. 58 +| |(% style="width:197px" %)+targetStructureUsage|(% style="width:568px" %)Association to the target Dataflow. 59 +|ComponentMap|(% style="width:197px" %)((( 59 59 Inherits from 60 60 //AnnotableArtefact// 61 -)))|Links source and target Component(s) where there is a semantic equivalence between the source and the target Components. 62 -| |+source|Association to zero or more source Components. 63 -| |+target|Association to zero or more the target Components. 64 -| |mappingRules|((( 65 -Reference to either a 66 -RepresentationMap, an 67 -EpochMap or a DatePatternMap. 62 +)))|(% style="width:568px" %)Links source and target Component(s) where there is a semantic equivalence between the source and the target Components. 63 +| |(% style="width:197px" %)+source|(% style="width:568px" %)Association to zero or more source Components. 64 +| |(% style="width:197px" %)+target|(% style="width:568px" %)Association to zero or more the target Components. 65 +| |(% style="width:197px" %)mappingRules|(% style="width:568px" %)((( 66 +Reference to either a RepresentationMap, an EpochMap or a DatePatternMap. 68 68 ))) 69 -|FixedValueMap|((( 68 +|FixedValueMap|(% style="width:197px" %)((( 70 70 Inherits from 71 71 //AnnotableArtefact// 72 -)))|Links a Component (source or target) to a fixed value. 73 -| |value|The value that a Component will be fixed in a fixed component map. 74 -|//DateMap//|((( 71 +)))|(% style="width:568px" %)Links a Component (source or target) to a fixed value. 72 +| |(% style="width:197px" %)value|(% style="width:568px" %)The value that a Component will be fixed in a fixed component map. 73 +|//DateMap//|(% style="width:197px" %)((( 75 75 Inherits from 76 76 //IdentifiableArtefact// 77 -)))| 78 -| |freqDimension|The Dimension or Attribute of the target Data Structure Definition which will hold the frequency information for date conversion.
