Integrating with HL7 applications

Use HL7 nodes in a message flow to integrate HL7 clinical applications.

To use the data from HL7 applications in message flows, complete the following steps:

1. Collect connection information about your HL7 applications.
2. Import the appropriate message model into your workspace.
   • If you are using the DFDL message model:
     1. Make sure that you are using the documentation that is integrated with the IBM Integration Toolkit.
     2. Click Resources for the Healthcare: HL7 to HL7 DFDL pattern to open the document that contains the resources for the pattern.
     3. Click the appropriate link in the document to import the required version of the DFDL message model (HL7 version 2.7, HL7 version 2.6, or HL7 version 2.5.1 or earlier)
     Note: The DFDL message models occupy a significant amount of memory, so you should import only the DFDL message model that you require. Also, to improve the performance and reduce the deployment time of the message flows, you can delete the chapters that you do not need from DFDL message model that you import.
   • If you are using the HL7v25P message set:
     1. Make sure that you are using the documentation that is integrated with the IBM Integration Toolkit.
     2. Click Resources for the Healthcare: HL7 to HL7 pattern to open the document that contains the resources for the pattern.
     3. Click Import the sample resources into your workspace to import the HL7v25P message set.
3. Create a message flow and add the appropriate HL7 nodes. For information about the available HL7 nodes and their purposes, see HL7 nodes in message flows.
4. Complete your message flow.
