HL7-Definition V2

Hello HL7 community, we’ve decided to give the old HL7-Definition reference website its well-deserved retirement. We’re now proud to introduce the new and improved HL7-Definition V2 website.

We’ve been asking for your feedback for the last few months, and for a good reason :-). By popular demand, we’ve included some new features, including:

  • More detailed specification descriptions
  • Standard HTTPS, removing the need to use custom ports
  • A more convenient and user-friendly search feature
  • Improved overall performance
  • Mobile friendly

Coming soon

  • Offline support
  • Message decoder – See field names in HL7 messages
  • Message validator – Validate the message is inline with the standard
  • FHIR specification support
