Using the FHIR Validator to transform content

This page describes how to use the validator to transform content from one format to another using the [FHIR Mapping Language]. To use the validator for validation, see Using the FHIR Validator

Running the validator

To use the validator, download the jar from http://build.fhir.org/downloads.html. Specifically, download the official FHIR validator at http://build.fhir.org/validator.zip Note that you always use the current validator from the build, irrespective of what transforms you are running.. You need a current version of java to run the validator:

 java -jar org.hl7.fhir.validator.jar -transform  [params]

The params control how the transfomration occurs, and are documented here.

In general, in order to perform the transform, you need to specify:

• what to transform
• the map to use to transform it
• where to put the tranform

+ you need to tell the engine where to find all the relevant logical models, mapping libraries, etc.
