# openEHR-technical Digest, Vol 35, Issue 33 **Category:** [Technical (archive)](https://discourse.openehr.org/c/technical-archive/156) **Created:** 2015-01-20 16:27 UTC **Views:** 1 **Replies:** 3 **URL:** https://discourse.openehr.org/t/openehr-technical-digest-vol-35-issue-33/15343 --- ## Post #1 by @WILLIAM_R4C Someone in the OpenEHR world created a nice CDA that uses archetypes\. It was presented at several meetings in the HL7 space, in particular in the patient care workgroup\. However, it was a powerpoint\. The HL7 people asked for the ppt, but that was never delivered\. The HL7 people asked the openEHR example of CDA with archetypes, but that was never delivered\. So the solution was told to be exist \(CDA filled with archetypes\), but not made available\. So it in fact does not exist\. The world of CDA around the world talks a lot about templates\. In all IGs there are specs how such a template should / would look\. But after 15 years since the conceptualization of HL7 templates, these are non existent\. \(I mean not findable even to insiders\)\. Met vriendelijke groet / With kind regards, dr\. William T\.F\.

However, Nehta is notoriously sensitive with IP, and may well have refused them to be made public\. I have also seen some other technical solutions, something like proof\-of\-concept level solutions with CDA containing archetyped data; none of these was operationalised \(it was done in Aus and UK\)\. I have no idea if any of these are alive today, or even relevant\. So at a practical level, you may be right ;\-\) I suspect the only place to get any serious CDA templates at all is MDHT / VHA\. I have no idea on the current status there though\. By the way, in case you are interested, we will have single\-file ADL 2 templates demonstrable in the next ADL Workbench, and I will post some early information / screen shots here imminently\. \- thomas --- ## Post #3 by @yampeku When you talk about 'CDA with archetypes', what do you exactly mean? 1\) An example of embedding an archetyped openEHR instance in a CDA document\. 2\) An example of the use of creating CDA templates equivalent to openEHR archetypes \(or vice\-versa\)\. 3\) An example of CDA templates defined as AOM archetypes using CDA Reference Model\. The last one is how we approached the problem and has been presented in several forums, with several examples already publicly available\. --- ## Post #4 by @Heath_Frankel3 Hi Tom, In fact this was demonstrated at MIE in 2007 and again at least once if not twice at HIC as part of IHE showcase that included storing the result in the GE XDS. Chris Lindop and other HL7 members were involved in the overall showcase so they new it existed for real. This had nothing to do with NEHTA but we certainly discussed with them and they still ask questions every now and then. It is likely that we will be doing thus in a production system in the not to distant future depending in what a receiving system wants to receive. Whenever we have discussed with a customer/vendor the options to use CDA or TDD/openEHR, the later is chosen. If HL7 people asked for it then they asked the wrong people. I guess they didn't really want to know about it.
