SNOMED CT Transformation and Template Service

Overview

SNOMED Transformation and Template Service is a REST API with the following functions:

  • Authoring using SNOMED Templates
  • Searching concepts by template logically, lexically or both
  • Generating new concepts that conformed to a given template
  • Transforming concepts from a source template to a destination template

Getting the Application Jar

Download the jar from the latest release page

... or if you would like to build the jar manually use maven:

mvn clean package

Then copy the jar from the target directory.

General Spring Boot Configuration Advice

The default configuration of this Spring Boot application can be found in application.properties. The defaults can be overridden by creating an override application.properties, file in the same directory as the jar, containing just the options you want to override. Alternatively options can be set using command line arguments, for example set a different HTTP port:

java -Xmx3g -jar target/snomed-template-service*.jar --server.port=8081

For other options see Spring Boot Documentation.

The default username and password (user:password) can be changed using the security.user.name and security.user.password properties.

Application Setup

Create an application directory to contain the jar file and other configuration files.

Clone the snomed-templates repository into the application directory. These templates will be loaded by the service to be used for concept authoring and transformations. To improve performance the templates are cached. POST /templates/reload will clear all caches and should be used when new templates are created/ added to the snomed-templates store. The snomed-templates store is configured via templateStorePath configuration option.

Clone this snomed-template-service repository and copy the transformation-recipes directory into the application directory.

Mandatory Configuration

The service needs to connect to the Snowstorm terminology server for querying SNOMED CT concepts using the terminologyserver.url configuration option.

Running the Application

Once setup is complete run the application:

java -Xmx3g -jar target/snomed-template-service*.jar

Building for Debian/Ubuntu Linux

A Debian package can be created using the 'deb' maven profile.

mvn clean package -Pdeb
