Don't know that much about HL7 but I thought it only specified the format of the messages, not the method of delivery. There are several commercial HL7 interface engines for sale that can handle distribution and communication of the messages. To talk to them in Uniface you could use 3GL or Java call in/out, REST services that you build using DSP's, SOAP webservices or whatever. It al depends on the technical requirements of the interface engine. Or you could build your own specialized interface engine in Uniface, the requirements then depend on all the system that your engine needs to communicate with.
