Implementing HL7: from the standard's specification to production application.

A C++ implementation of the HL7 health-care data interchange standard was developed by automatic methods applied to the authoritative specification of the standard. The reusable class library thus created presents an intuitive, flexible, and easy-to-use application programming interface to the HL7 protocol. This allows HL7 applications to be developed quickly while a high conformance to the standard is ensured.
