qpp-conversion-tool

Installation Instructions

Prerequisite Software

Before you can use the qpp-conversion-tool application, you must install and configure the following products on your machine:

  • Git and/or the GitHub application.

    GitHub's Guide to Installing Git is a good source of information.

  • Java Runtime (version >= 1.8).

    It is important that you have the right version of java on your path.

    # When you run 'java -version', you should get 1.8.XXXXX. For example:
    java -version
    java version "1.8.0_144"
    ...

    Sometimes the Java Runtime installer doesn't update your path. So you must do it manually. Alternatively, download and install the Java Development Kit (version >= 1.8). The JDK is better at updating your path.

  • Maven (version >= 3.3).

    Maven is used to build the application, manage dependencies, and run tests. After you unzip the Maven archive, you need to add the bin directory to your path, as described the Maven installation instructions.

    # When you run 'mvn -v', you should get 3.3.X. For example:
    mvn -v
    Apache Maven 3.3.9
    ...
  • Docker.

    Docker is not required but is an alternative to the above requirements if all you need is to run the converter.

Getting the Converter

Use the GitHub application or the command line to clone this repository.

# Clone the GitHub repository.
git clone https://github.com/CMSgov/qpp-conversion-tool.git

# Go to the qpp-conversion-tool directory.
cd ./qpp-conversion-tool

Running the Converter

ReST API via Docker

The Conversion Tool can be executed through a ReST API. Using the ReST API has the added benefit of having the QPP validated if you so choose. For the examples below, make sure you're in the qpp-conversion-tool directory.

Starting the API Endpoint

# Build the Docker image and run the container using docker-compose.
docker-compose -f ./docker-compose.test.yaml up

Invoking the Endpoint

curl -X POST \
  http://localhost:3000 \
  -H 'cache-control: no-cache' \
  -H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \
  -F file=@./qrda-files/valid-QRDA-III-latest.xml

The response body will either be the QPP JSON on success or error JSON on an error. The HTTP Status will be 201 Created on success or 422 Unprocessable entity on an error.

Submission Validation

While the converter will validate the format of the QRDA-III file and some basic semantics, deeper semantic checks are only available if you enable the public submission validation API. If any errors are found by the public submission validation API, error JSON will be returned from the ReST API like normal.

To enable the public submission validation API, modify the .env file with VALIDATION_URL=https://qpp.cms.gov/api/submissions/public/validate-submission and then restart the ReST API endpoint.

Ensure the environment variable CPC_END_DATE is set to a valid date, in the format YYYY-MM-DD, or a validation error may be thrown.

Command Line

For the examples below, make sure you're in the qpp-conversion-tool directory.

Note: If you are using Windows, replace ./convert.sh in the examples below with convert.bat.

Convert a File

# Try the convert script. If the JAR isn't built yet, the script will build it for you first.
./convert.sh ./qrda-files/valid-QRDA-III-latest.xml

If a QRDA-III XML file is successfully converted, a QPP JSON file is created in the current working directory. The file name will have the same name as the input file but with the extension .qpp.json. For example, valid-QRDA-III-latest.qpp.json.

When an invalid file is provided to the converter, an error JSON file is created in the current working directory. The file name will be the same as the input file but with the extension .err.json. For example, not-a-QRDA-III-file.err.json. This error file contains descriptions and XPaths that help in identifying the errors in the provided input file.

View all commands with convert.sh.

Sample files

Sample QRDA-III files that cover all of the eCQM, PI, and IA measures as well as other scenarios can be found in the sample-files folder.
