The HL7 Development Framework
The basis for all products in V3 are models:
symbolic, structured representations of (part of)
the real world
• The UML (Universal Modelling Language) is the
most commonly used modelling format
– HL7 uses minor variations
• Models in V3 offer a ‘language’ for understanding

and recording of the contents, the structure (static
aspect) and the behaviour of information
exchange in healthcare (dynamic aspect)
• Message specifications are the result of
combining data and process models: when do I
sent what?
• HDF HL7 Development Framework
• Storyboards
• RIM Reference Information Model
• D-MIM Domain Message Information Model
• R-MIM Refined Message Information Model

• HMD Hierarchical Message Description
• MT Message Types
• TE Trigger Events
• IN Interaction Model
• AR Application Roles
• ITS Implementation Technology Specification
• Structured method to start with a description of
the real world for a certain domain and derive:
– An information model for the domain (static model);
– An interaction model for the domain (dynamic model);
– And finally: message specifications that bind a static

model to a dynamic model.
• The HDF is not required knowledge to
implement V3 interfaces, but it is necessary to
understand why they are the way they are. |
