HL7 Version 3 Standard: XML Implementation Technology Specification - Wire Format Compatible Release 1 Data Types, Release 1

DESCRIPTION

This is the Wire Format Compatible Release 1 Data Types (XML ITS R2B) for datatypes. It implements a subset of the Abstract Data Types R2 with a wire format that is mostly backwards compatible with ITS R1. Note, however, that while the wire format is mostly backward compatible, the datatypes themselves are not strictly backwards compatible. The intent of this ITS is not to mean that implementations do not need to change, but that this ITS means that existing instances may not need to be modified.

This is a bridge specification to allow a smooth transition between Datatypes R1 and Datatypes R2. For that reason HL7 does not expect to renew this specification after 5 years and may consider withdrawing it sooner. HL7 Work Groups should not develop specifications that are dependent upon ITS R2b unless there is an extant, demonstrable implementation of the earlier standard that justifies such backwards compatibility. It should never be used for new, unrelated endeavors. Further, specifications that are dependent upon this specification must begin planning a transition to DT R2 to take effect prior to the expiry of this specification. Permission of HL7, with responsibility delegated to the TSC, is required to use this specification to create HL7 standards.

ALTERNATIVE NAMES

HL7 Version 3 Standard: XML Implementation Technology Specification - Wire Format Compatible Release 1 Data Types, Release 1 may also go by the following names or acronyms:

"Reaffirmation of V3: XML ITS - Wire Format Compatible Release 1 Data Types, R1","V3 XML ITS Wire Frame Compatible R1 Data Types, R1",Data Types R2B,XML ITS,R2B changed to retired for 10 year inactivity by KVH and LL 9/21/2022

TARGETS

  • All Implementers
  • Health Care IT Vendors

BENEFITS

  • Enables an easier transition from Datatypes 1 to Datatypes 2 for parties who need to maintain wire format compatibility with Datatypes R1. However, it does require TSC approval to use these Datatypes and they are temporary in that they will only be available for use a limited timeframe.
  • Allows a smooth transition between Datatypes R1 and Datatypes R2 as a bridge specification. This document describes the Data types R2 with a wire format that is mostly backwards compatible with the Data Types R1 wire format.
