Hi Greg
No - we are not on the same page yet. Let me go back a step. The demographic service (patient look up, address, date of birth etc) is usually already existing when we add an EHR service. For this reason openEHR, although it has a demographic model, has not had pressure to implement it. The archetypes that you found on the openEHR site were built by hand to demonstrate the application of ADL to another reference model (you will find HL7 RIM archetypes as well). Archetypes are specific to a reference model class - and the demographic and EHR models are not the same (but data structures, clusters, elements are shared by both). So it is possible to share cluster archetypes in the EHR and demographic environments. So archetypes of PARTY in the demographics area cannot be used in the EHR - but a cluster for name or address can be. Does that make sense now? The newer ones under the person icon in CKM conform to the demographic model . These have been created in Brazil. There are cluster archetypes that also have demographic features - which can be stored in the EHR (remember that the EHR model and Demographic model share the cluster class. I hope that helps - Sam From: openehr-technical-boun...@openehr.org [mailto:openehr-technical-bounces at openehr.org] On Behalf Of Greg Caulton Sent: 16 March 2009 22:59 To: openehr-technical at openehr.org Subject: RE: Why is the editor not opening ADL files? I am confused - hopefully you saying that those particular 'older' demographic models are not supported? But there are newer ones right being added to the CKM that conform to the ADL structure the other clinical ADLs use? You are not saying an AQL query for Women over 50 - 70, last mammogram > 2 years cannot be supported because demographics are not relevant? ------------------------------ Message: 4 Date: Mon, 16 Mar 2009 16:46:46 +0930 From: "Sam Heard" <sam.he...@oceaninformatics.com> Subject: RE: Why is the editor not opening ADL files?

These archetypes are not in the EHR. The EHR and demographic service can share archetypes like data_structures, clusters and elements and for this reason it is worth aligning them. The Ocean archetype editor was built before ADL and works by using the ADL parser and XML parser. The reference model is hard coded as a class. TO work with another reference model it is necessary at the moment to hard code another class. A generic approach to this is possible and may in time be useable. In the meantime, I just want to be clear that the demographic model archetypes cannot be used in the EHR - they are not relevant there.
