Definition of Type of Referenced Data Code System: HL7 v2+ Specification Update
CodeSystem: Type of Referenced Data (2.3.1 - 1.2.0) (Experimental)
Summary
HL7 has published the definition for the code system 'Type of Referenced Data (2.3.1 - 1.2.0)', which declares the general type of media data that is encoded. Although it was used in versions prior to v2.5.1 and later replaced by IANA media types, it remains an important referenced specification.
Details
This document provides technical reference information for the code system 'Type of Referenced Data (2.3.1 - 1.2.0)', defined by HL7. This code system is used to declare the general type of media data that has been encoded. Historically, it was utilized in v2.5.1 interfaces and earlier, but it was replaced by a standard coding system using IANA media types after HL7 version 2.6. The specification details multiple codes, such as 'AP' (Other application data), 'AU' (Audio Data), and the latest 'TEXT' (Machine readable text document). Each code is assigned an introduction version (e.g., HL7 V2.3 and later) and a status (Active, Inactive, etc.), which helps in clearly classifying the type of data. This information is crucial for maintaining standardization and interoperability regarding media data types in healthcare information exchange. Even as modern standards like FHIR become dominant, these code definitions are still referenced when linking with legacy HL7 v2 interfaces or interpreting historical data, making understanding this specification necessary.
