Before you use HL7 Module to parse or create HL7 version 2.x messages, you need to generate the data model and the IS document type for the supported HL7 message versions. The generated IS document types serve as input to the service that you use to create HL7 messages.

For HL7 messages version 2.x, HL7 Module generates IS document types for each HL7 message type based on message definitions (XML schemas) across HL7 versions using HL7 Module services.

For HL7 messages version 3.0, HL7 Module provides only valid HL7 version 3 schemas. The HL7 version 3 XML schemas are installed with HL7 Module and located in the IntegrationServer_directory\packages\WmHL7\data\v3 directory. You must use the Integration Server built-in services for generating IS document types for HL7 3.0 messages as described in the webMethods Integration Server Administrator’s Guide for your release.
