Re: Term bindings in archetypes and templates
Hi Mikael, You may be interested in our mapping tool, Snapper, which is designed to tackle this problem for mapping to (not from) SNOMED CT. It provides extensive support for mapping to post-coordinated expressions where single-concept maps are not possible and can be used to create unofficial extensions to SNOMED CT. More details and a short screen-cast are on our website http://aehrc.com/snapper Cheers, michael -- Dr Michael Lawley Principal Research Scientist The Australia e-Health Research Centre http://aehrc.com/ +61 7 3253 3609; 0432 832 067 "Ein Flügel und einen Schnabel machen kein Vogel" On 11/03/10 9:49 AM, "Mikael Nyström" <mikael.nystrom@liu.se> wrote: Thomas Beale wrote: > On 10/03/2010 22:16, Mikael Nyström wrote: >> I belong to a group that, except for openEHR related research, also >> do >> research about terminology systems and terminology systems mapping. >> During mapping from one terminology system to another terminology >> system is it quite common to be unable to map properly, because the >> two >> terminology systems have divided the domain in different ways.

I agree that we have to wait and see how much problems we will get. That was also my reason to reply to Sebastian's e-mail which told that there is no problem to add terminology bindings after the archetypes are finalized. However, I didn't refer to "theoretical worst case". I referred to actual problems that have appeared for us during both our research work and in our national SNOMED CT project in Sweden.
