1.1 | 7 | An //ItemSchemeMap// is an abstract container to describe mapping rules between any item scheme, with the exception of Codelists and ValueLists which are mapped using the RepresentationMap. A single source //ItemScheme// is mapped to a single target //ItemScheme//. The //ItemSchemeMap// then contains the rules for how the values from the source //ItemScheme// map to the values in the target //ItemScheme//. Each source value may match a substring of the original data (using startIndex and/or endIndex) or define a pattern matching rule described by a regular expression. The target value is provided as an absolute string, although it can make use of regular expression groups to carry across values from the source string to the target string without having to explicitly state the value to carry. An example is a regular expression which states ‘match a value starting with AB followed by anything, where the //anything// is marked a capture group’, the target can state ‘take the //anything// value and postfix it with AB’ thus enabling the mapping of ABX to XAB and ABY to YAB. |

1.1 | 18 | |
| 19 | An ItemSchemeMap is an abstract type which inherits from Maintainable. It is subclassed by the 4 concrete classes: | ||
| 20 | |||
| 21 | * OrganisationSchemeMap | ||
| 22 | * ConceptSchemeMap | ||
| 23 | * CategorySchemeMap | ||
| 24 | * ReportingTaxonomyMap | ||
| 25 | |||
| |
5.1 | 26 | An OrganisationSchemeMap maps a source AgencyScheme, DataProviderScheme, DataConsumerScheme or OrganisationUnitScheme to a target AgencyScheme, DataProviderScheme, DataConsumerScheme or OrganisationUnitScheme. It is permissible to mix source and target types to define an equivalence between Organisations of different roles. The mapped items refer to the Organisations in the source/target schemes. |
| |
1.1 | 27 | |
| 28 | A ConceptSchemeMap maps a source ConceptScheme to a target ConceptScheme. The mapped items refer to the Concepts in the source/target schemes. | ||
| 29 | |||
| 30 | A CategorySchemeMap maps a source CategoryScheme to a target CategoryScheme. The mapped Items refer to the Categories in the source/target schemes. | ||
| 31 | |||
| 32 | A ReportingTaxonomyMap maps a source ReportingTaxonomy to a target ReportingTaxonomy. The mapped Items refer to the ReportingCategory in the source/target schemes. | ||
