Mapping Editor

CTS2-LE provides a web interface that enables a user to create, update or delete a mapping. This section describes both the conceptual background and technical aspects concerning this mapping editor.

FHIR Concept Map

The conceptual background is given by means of the FHIR ConceptMap - which defines a mapping as a "statement of relationships from one set of concepts to one or more other concepts - either code systems or data elements, or classes in class models." In order to represent a mapping that is conformant to both the CTS2- and the FHIR specification, a transformation between the given meta-models is necessary. The following table outlines how FHIR ConceptMap elements are represented by CTS2 elements.

FHIR element [datatype]	CTS2 mapping	Notes
url [uri]	MapVersion.aboutUri, MapVersion.alternateAboutUri	uniqueness within the server instance in wich the mapping is stored is guaranteed
identifier [identifier]	-
version [string]	MapVersion.versionID
name [string]	MapVersion.resourceID	uniqueness within the server instance in wich the mapping is stored is guaranteed
status [code]	ResourceDescription.status	only codes from the FHIR ConformanceResourceStatus value set can be used

sourceUri [uri]	MapVersion.source.aboutUri	should be equal to element.codeSystem
targetUri [uri]	MapVersion.target.aboutUri	should be equal to element.target.codeSystem
element	MapVersion.entry
element.codeSystem [uri]	MapVersion.entry.aboutUri	should be equal to sourceUri
element.code [code]	MapVersion.entry.name
element.target	MapVersion.entry.target
element.target.codeSystem [uri]	MapVersion.entry.target.aboutUri	should be equal to targetUri
element.target.code [code]	MapVersion.entry.target.name
element.target.equivalence [code]	MapVersion.entry.target.correlation	only codes from the FHIR ConceptMapEquivalence value set can be used
element.target.comments	????
element.target.dependsOn	-
element.target.product	-

The following constraints and limitations have been formulated or noticed:

• There are a couple of FHIR elements that are currently not represented by means of CTS2, among these are

Technical Implementation

The application will be created with AngularJS (version 1.3.15) and UI bootstrap components (0.13.1) written in AngularJS. As of 10.02.16, the mapping editor has not been made available.
