HL7 delivers healthcare interoperability standards

HL7 Harmonization Meetings

HL7 harmonization meetings are held four times a year. The purpose of these meetings are to build upon and refine the Reference Information Model (RIM). The RIM is the model of record for specification of the information content of HL7 messages. The harmonization process is: 

  • Contributions to the RIM are made by the HL7 Technical Committees and Special Interest Groups and by ANSI accredited Standards Developing Organizations (SDO). 
  • No changes are introduced to the RIM without first providing an opportunity for the entire HL7 working group to review and comment on the proposed change. 
  • Following a defined comment period, representatives from each Technical Committee review the proposed changes, along with any comments received from the working group. 
  • A consensus process is used to determine which of the proposed changes are actually applied to the RIM. This process, referred to as "harmonization," ensures that the RIM is a shared view of the entire working group.

The harmonization process therefore has a potential impact for those working with the RIM in the UK. Before each meeting the list of proposals is available and once each harmonization meeting is complete all the data is compiled together in one complete downloadable package.
