Package File

The following package file includes an NPM package file used by many of the FHIR tools. It contains all the value sets, profiles, extensions, pages, and URLs in the IG which are defined as part of this version of the Implementation Guides. This file should be the first choice whenever generating any implementation artifacts since it contains all of the rules about what makes the profiles valid. Implementers will still need to be familiar with the specification’s content and profiles that apply to make a conformant implementation. See the overview on validating FHIR profiles and resources:


All the Examples that are used in this Implementation Guide are available for download:

Example Flow Charts:

These example flow charts were created to assist the TestScript and Reference Implementation development team and are provided here to assist developers in implementing CDEX transactions. They are examples only, and actual workflows may differ from them.

Individual flowcharts ( the text between the ''') can be viewed using flowchart.js. flowchart.js is a flowchart DSL and SVG render that runs in the browser and terminal. For more information, see https://flowchart.js.org/. Alternatively, this page can be viewed at https://hackmd.io/.
