It makes sense, but I will have to find time to dig into the differences between the EHR and Demographic reference model classes and understand why they need to be different.
And then determine once we have added one more reference model class, how many more will need to be added to achieve a standalone HIS to address administrative processes - billing, admission, discharge etc. At this point it doesn't seem to make sense to build a new administrative reference model for the non-EHR content. Better to stick with HL7 and other standards than to reinvent the wheel. > > Message: 1 > Date: Fri, 20 Mar 2009 14:58:59 +0930 > From: "Sam Heard" <sam.heard at oceaninformatics.com> > Subject: RE: Why is the editor not opening ADL files? > To: "'For openEHR technical discussions'" > ? ? ? ?<openehr-technical at openehr.org> > Message-ID: > ? ? ? ?<02ce01c9a91c$c6767440$53635cc0$@heard at oceaninformatics.com> > Content-Type: text/plain; charset="us-ascii" > > Hi Greg > > > > No - we are not on the same page yet.
