A user has a group of caDSR common data elements which have been used in form construction in the past. Now the user would like to move these forms to the HL7 CDA structure. The user finds it possible to represent a portion but not all of the contextual meaning of the data elements in 11179. The user would like to transform the CDEs to HL7 V3 class structures in order to get the full contextual meaning as used in the CDA document. The user would like to submit the list of CDEs to the ECCF registry transformer and have a set of V3 object classes returned.

6 - Creation of Value Sets and Value Set Mappings

A user has identified one or more sets of permissible values that need to be mapped to standard codes used by the vocabulary and common data elements workspace.  These values need to be assembled in a format such as Excel, XML or simple tab separated values and then be uploaded to a service that will allow them to be mapped to the codes that are endorsed for interchange on the grid.  The user must be able to locate existing value sets and to construct new ones where appropriate targets do not exist.  The user needs to be able to instruct the service to do automatic first approximation at a mapping, and then needs to be able to search, refine and validate mapping, the ability to record a "quality" metric that states how closely the mapping actually approximates the intent of the original value.  The user may encounter potential problems and omissions during this process and will need to submit suggested changes and enhancements to the appropriate oversight body for potential enhancement.  Once created, the user needs to be able to download the resulting mappings in an electronic format such as Excel, XML, etc. as well as to submit the mappings to a service, either local or centralized, that will represent the mappings via a standardized API.
