3.3. Release Format 2 Update Guide 3.3.1. Introduction 3.3.1.1. Purpose The purpose of RF2 is to provide a format that is flexible, unambiguous and useful. Its primary aim is to strengthen SNOMED CT by providing a format that is simple and stable, while enabling innovation through adaptations to cater for changing requirements. This specification was developed by harmonizing proposals reviewed by the IHTSDO Enhanced Release Format Project Group, including: • The Enhanced Release Format Specification (International Health Terminology Standards Development Organisation. SNOMED Clinical Terms ® Enhanced Release Format Proposed Specification , 21 June 2007). • The Reference Set Specification (International Health Terminology Standards Development Organisation. SNOMED Clinical Terms ® Reference Sets - Proposed Specification , 31 July 2007). • The Alternate Release Format proposed by NEHTA in coordination with their Australian Affiliates. 3.3.1.2. Who should read this guide? The intended audience for this guide includes technical professionals who are involved in the development and/or implementation of healthcare information systems that use SNOMED CT. For detailed technical guidance on the existing Release Format, please consult the SNOMED CT Technical Reference Guide (TRG) and SNOMED CT Technical Implementation Guide (TIG), as well as other applicable technical documentation described in the Associated Documentation table. For technical guidance on using Release Format 2, please consult the "SNOMED CT Release Format 2 - Reference Set Specifications" and the "SNOMED CT Release Format 2 - Data Structures Specification" documents on the Collaborative site. 3.3.1.3. Associated Quality Measures Although the definition of quality measures to monitor the implementation of this standard do not fall under the scope of this guide, they will be covered by the documentation covering the QA and Release process for the Workbench. 3.3.1.4. Summary of Changes Formats | 271 The RF2 introduces a number of new concepts and capabilities.These are summarized below, and described in more detail later in this guide: • Addition of an Identifier file to allow components to be identified by an arbitrary number of Identifiers from an arbitrary number of Identifier schemes; • Addition of a module Identifier field to all components, enabling the source module in which each component is maintained to be identified, facilitating configuration management; • Modified handling of the language and dialect properties of descriptions, for reduced complexity with increased utility; • Introduction of concept enumerations making enumerations within SNOMED CT more easily extensible, self contained within the terminology (not dependent upon external documentation) and easily compatible across multiple languages; © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
