Letter to RFH Readers. Grahame Grieve 13-Aug 2011. This specification arose from the remit of the HL7 Fresh Look Taskforce: if HL7 started again from scratch with a new specification, what would a goo...

I recently joked that HL7 v3 is still at a turning point, like one of my son's Choose You Own Adventure books. This screen capture from Graham Grieve's Health Intersections blog recently is perhaps an indication of the signposts facing HL7 v3:
