TBD: This is where profile components like official data type flavors should be listed.
TBD: This is where implementations begin and guides should be listed. Maintaining the implementation guides on this platform will be too tedious, so that a list with hyperlinks should be sufficient.
V2+ is an initiative to modernize the widespread, dependable V2 standard. It will give implementers worldwide a new and modern way to access and use the specifications in their efforts. The initiative will make it easier for HL7 to develop and maintain the V2 standard as the workhorse specification of worldwide healthcare data exchange. The goals of presenting the V2 standard in a web-based format include:
As part of this For Comment ballot, the majority of technical content remains unchanged from V2.9 except where necessary to achieve the new format (eg. the consolidation of duplicate message structures). Only the presentation of the content has changed. We are specifically requesting feedback on the organization of the content in the new web-based format including:
While this ballot includes many of the features that will be central to V2+, several issues still need to be resolved including:
We invite feedback on how to best implement solutions to these outstanding issues.
