7 -An //ItemSchemeMap// is an abstract container to describe mapping rules between any [[item scheme>>doc:Glossary.Item scheme.WebHome]], 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.
