The cqf-ruler is based on the HAPI FHIR JPA Server Starter and adds a set of plugins that provide an implementation of FHIR's Clinical Reasoning Module, serve as a knowledge artifact repository, and a cds-hooks compatible clinical decision support service. The cqf-ruler provides an extensibility API to allow adding custom FHIR operations without the need to fork or clone the entire project.

The public sandbox is not persistent, has no authentication, and is regularly reset. Do not store any sensitive data, PHI, or anything you need to be persistent on the sandbox:
The easiest way to get started with the cqf-ruler is to pull and run the docker image
docker pull alphora/cqf-ruler
docker run -p 8080:8080 alphora/cqf-rulerThis will make the cqf-ruler available on http://localhost:8080
Other options for deployment are listed on the wiki for more documentation.
The cqf-ruler provides the HAPI FHIR Tester UI which allows FHIR Resource CRUD at the server base url. That's http://localhost:8080 if you're running with the Docker command above.
The cqf-ruler provides Swagger UI for the REST API and test interface at http://localhost:8080/fhir/swagger-ui/.
Similarly, Open API docs are available at http://localhost:8080/fhir/api-docs.
The wiki provides walkthroughs of several of the features of the cqf-ruler such as Quality Measure Processing.
In general, you need to load the cqf-ruler with FHIR Resources prior to using it. One way to do this is to start a cqf-ruler server and use the FHIR REST API to load resources. See Resource Loading on the wiki for a description of how to do that.
This project includes the hapi-fhir-jpaserver-starter project as a submodule and includes the compiled classes as a jar called cqf-ruler-external. Be sure to use the following command when cloning this repository to ensure the submodules are initialized correctly:
git clone --recurse-submodules https://github.com/DBCG/cqf-ruler.git
or if you've already checked out the repo, use
git submodule update --init --recursive
to clean up any unneeded or unused files, use:
git clean -fdx
Go to http://www.oracle.com/technetwork/java/javase/downloads/ and download the latest (version 11 or higher) JDK for your platform, and install it.
This project uses the Maven wrapper to ensure the correct version of Maven is available on your machine. Use ./mvnw to invoke it.
