Interoperability Paradigm

Interoperability paradigm (IP)

Interoperability paradigm (IP) is a set of fundamental principles that establishes the ground rules for the different approaches to HL7 V3-based information exchange. The IP must answer

1. When information is exchanged.
2. How application implementation details are specified.
3. How templates are to be used.
4. In what form it is exchanged. The HL7 interoperability paradigms are messages, documents, and services:
   1. Messages - The transmission of semantically rigorous, contextually self-contained information structures according to pre-determined trigger conditions along well known interaction paths.
   2. Documents - A business-oriented container that becomes the focal class that may be exposed through a service interface (for administration, querying, and manipulation), or transmitted via a message.
   3. Services - A structured behavioral interface being exposed that provides fine-grained control of some capability, often a focal class, such as an order or a transactional process. These capabilities are, in turn, invoked through smaller, function-oriented message structures that retain the semantic rigor of HL7 models without realizing the entirety of the semantic in the message structure.
