HL7 to HL7 Map

Create a Component

You’ll notice the Translator contains a simple script and sample HL7 data that demonstrates the workflow for converting HL7 v2.6 ADT A01 messages to v2.7 ADT A01 messages:

1. Parsing an inbound HL7 message with the inbound VMD (ex. VMD/ADT_2_6.vmd).

2. Initializing the HL7MAP Library using the HL7MAPinit function and specifying the directories containing the mapping and/or filtering modules.

3. Filtering the inbound message using the HL7MAP library

4. Building the outbound message and mapping data from the inbound message using the HL7MAP library

5. Pushing the message to the queue for further processing or downstream delivery

You can cycle through the provided sample messages to see how the component handles different message types. This component also demonstrates https://interfaceware.atlassian.net/wiki/x/g4Cxog by ensuring any additional sample messages will not be stored in the commit history. The sample .gitignore file can be viewed in the component’s Bitbucket repository.

Since this is a feeder component, you’ll need a source component (ex. https://interfaceware.atlassian.net/wiki/x/FwBTog) to send messages to it and a destination component (ex. https://interfaceware.atlassian.net/wiki/x/V4CVog) that it can pass messages on for further processing or sending to a downstream system.

You can start the components and send a stream of sample messages from a https://interfaceware.atlassian.net/wiki/x/NgCUog component to see how the mapping and filtering is handled.

The default filtering module checks for messages with an in_message_type of “Catchall” and returns true to filter these messages out. It returns false for all other messages.
