Table of Contents

Exporting a Knowledge Module to OpenCDS is currently a manual process.

...

  1. The opencds-decision-support-service war (v1.1.5), or
  2. Specified in the OpenCDS base properties file:
    1. $HOME/.opencds/opencds.properties
    2. %HOME%\.opencds\opencds.properties on Windows (deployed as a user)
    3. C:\.opencds\opencds.properties (deployed as a service)
    4. As specified as a server flag (see example configuration for details–TBD)

Configuration Overview

The current configuration requires the following folder hierarchy:

  • conceptMappingSpecifications
    • autoGeneratedMappings
      • folder containing auto-generated concept mappings
    • manualMappings
      • folder containing manually created concept mappings
  • knowledgeModules
    • folder containing knowledge modules exported from Guvnor (or other systems that generate knowledge packages)
  • resourceAttributes
    • folder containing OpenCDS configuration resources
    • knowledgeModules.xml
      • used for knowledge module metadata, for knowledge modules contained in the knowledgeModules folder (see above)
    • openCDSCodeSystems.xml
      • used to define the Code Systems supported by OpenCDS
    • openCdsExecutionEngines.xml
      • used to define which inferencing engines should be available to/used by OpenCDS
      • This file should not need to be modified except in certain cases.
    • semanticSignifiers.xml
      • Used to define which vMR versions are supported by the system.
      • This file should not need to be modified except in certain cases.
    • supportedConceptsConfigFile.xml
      • Used to indicate the supported concept for each OpenCDS Concept Type. (Unused during runtime.)

Export/Import Process

The steps for importing a Knowledge Module into OpenCDS are are as follows:

  1. If you are using new concepts, add them to the relevant folder within the conceptMappingsSpecifications folder (see Concept Mappings).
  2. If your Knowledge Module supports one or more Code Systems that are not currently specified in OpenCDS configuration, add them to openCDSCodeSystems.xml (see OpenCDS Code Systems).
  3. New Knowledge Module
    1. If Export the knowledge module is new, export it from Guvnor and place the downloaded binary package into the knowledgeModules folder (see Configuration Overview).
    2. Add an entry for the new knowledge module in knowledgeModules.xml (see Knowledge Modules).
  4. Replacing an Existing Knowledge Module
    1. If Export the knowledge module already exists and you want to replace it with changes made in Guvnor, you may from Guvnor and replace the existing module; be sure , ensuring the file name is consistent with the previous instance (see Configuration Overview).
  5. Restart OpenCDS (v1.1.5 and earlier).
