Overview
In some cases you will need to transform a list of CDA documents into vMR in order to be able to consume the OpenCDS service. Here, we describe how to take advantage of the open-source CDA Redaction Web service developed by the SHARPS DS2 project. We have packaged the CDA Redaction Web service along with other SHARP applications into the cdatovmr docker container. In order to describe its functionality, we make use of three components: cdatovmr container, opencds container and soapui as Web service client. The following figure provides an overview of the interaction between these components.
Deploy
Create opencds docker container
Please check the wiki page OpenCDS container for more details about how to build the opencds docker image.

sudo docker run -d -p 8080:8080 -p 8443:8443 -p 2222:22 --name opencds opencds/opencds:ubuntu |
Deploy cdatovmr container
Set up DSS client
Verify that opencds service is available by opening a browser on the URL http://localhost:8080/opencds-decision-support-service/evaluate?wsdl
Create cdatovmr docker container
Please check the wiki page cda2vmr container for details about how to build the image

sudo docker run -p 8081:8080 -p 2223:22 -p 4848:4848 -p 8181:8181 -p 9009:9009 --name cdatovmr -i -t opencds/cdatovmr |
Check that the following applications are available:
- Inference analyzer - http://locahost:8081/SimplePredicateReducerVisualizer-1.0-SNAPSHOT
- Predicate/Reducer - http://localhost:8081/opencds-decision-support-service-1.2.0-SNAPSHOT/evaluate?wsdl
- Predicate reducer Web service - http://localhost:8081/CdaService/Evaluate?wsdl
- Predicate reducer web application - http://localhost:8081/cda-ws-web/
For this demonstration we will only use the Predicate reducer Web service http://localhost:8081/CdaService/Evaluate?wsdl
