Introduction

This document is a section of the LexEVS 6.0 Programmer's Guide.

The Value Set services are integrated parts of the LexEVS API. It provide three major functions:

  • Administration- Ability to load, export and remove value set definitions
    • Loader - Ability to load Value Set Definitions programmatically into the LexGrid repository using the domain objects that are available via the LexGrid logical model
    • Exporter - Ability to export Value Set Definition and Value Set Resolution to a file in LexGrid XML format

    • Remove - Ability to remove Value Set Definition from the system

      Info
      titleNote

      These administration operations can be performed in LexEVS 'Local' environment only. This can not be performed using LexEVS Distributed environment.

  • Query - Ability to apply user restrictions (ex: valueSet URI) and dynamically resolve the definitions at run time
  • Resolve - Ability to resolve Value Set Definition dynamically against selected Coding Scheme Version(s) and return all the concepts belonging to the value set

...

Below is a sample XML file containing Value Set Definitions in LexGrid format that can be loaded using LexEVS Value Set Definition Service.
