HL7 v3 works by constraining the RIM for specific use cases. Several types of constrained models are defined (DMIM, RMIM, HMD, MT and CMET). These all use common types of constraint, including omission, cloning, multiplicities, constrained data types and code binding. HL7 has developed a special graphical notation for specifying constrained information models. The clinical statement pattern is a common pattern used for clinical information in various profiles. Implementation Technology Specifications (ITS) describe how information is expressed as XML on the wire.
