HL7 version 3

From Hl7book

Jump to: navigation, search

The HL7 version 3 standard has the aim to support any and all healthcare workflows. It consists of an elaborate set of ready-to-implement models (for messages, documents, or services) created using the HL7 Development Framework (HDF). These models are based on the object-oriented Reference Model (RIM) based HDF, which is an integral part of the standard. The RIM expresses the data content needed in a specific clinical or administrative context and provides an explicit representation of the semantic and lexical connections that exist between the information carried in HL7 messages, documents or services. The HDF, which is loosely based on the UML, documents the processes, tools, actors, rules, and artifacts relevant to development of all HL7 version 3 standard specifications.
