The Source transformation reads an XML file as a source. You can use a flat file connection or an SFTP connection to a remote server.

The Data Services transformation uses an HL7 serializer data service from the data services repository. The HL7 serializer reads the incoming patient and health information in the XML file and converts the data to an HL7 message.

You can get the name of the HL7 serializer data service by using the following format:

For example, HL7_2_6_ADT_A12_Serializer.

The Target transformation writes the HL7 messages to a target. You can use a flat file connection, an SFTP connection to a remote server, or an MLLP connection to write the HL7 messages to a flat file.
