termbinding constraints in the archetype editor
Everybody, I am trying to bind an attribute in an archetype to a value set from a terminology server. The data in the termserver is availiable through web services. In practice, it should thus be possible to specify a URI in an archetype constraint for the elementattribute. Can't figure out how this is meant to be done in AE. Anyone with experience of how to do this in practice? Does anyone know what the AE does when you enter the interface screen. Is the constraint executed, if not, when is the constraint executed (or is it executed at all?). References to AE user manual is also welcome. Can't find this.

Hi Jostein, Regarding your question about what AE does when you enter the interface screen: it is open source. In case you have someone who can speak vb.net, you can simply debug that part of the code and see what it does. Probably not the most practical way of knowing the answer, but the most certain one..

Jostein, as a possible work-around, we have used internal at-codes and mapped those at-codes to the external terminology. This, of course, only works if the number of allowed codes is limited, which have been the case in our projects so far. This also has the benefit that the archetype does not depend on external (terminology server) resources. If the terminology used is SNOMED CT, IHTSDO will (eventually) provide a standard for constraining expressions which will be applicable. This would though have to be implemented in your terminology server. Out of curiosity, what terminology server are you using?

Hi Jostein, This depends whether you got AE from the openEHR web site or from Ocean Informatics. * The openEHR build lacks a way of of connecting to a terminology server. * The Ocean informatics build, on the other hand, uses a proprietary component to connect to the Ocean Terminology Server (OTS). Why have two builds? Because AE is open source, and the inclusion of a proprietary component would prevent people from being able to build AE themselves. But people want this functionality, so the only solution was to do a separate Ocean build of AE, with the appropriate hooks to connect to OTS. In theory, any one who has the time and expertise could use those same hooks to connect to some other terminology service. So, once you've installed the Ocean build of AE, here's how to do it. First you have to configure AE to point to the web service that you want to use: 1. Under the Tools menu, select Options. 2. In the Options dialog, select the File Locations tab. 3. Tick Enable Terminology Lookup. (This is not available in the openEHR build.) 4. Enter the web service URL into the URL for Terminology Service box. (This isn't in the openEHR build either.) 5. Click OK. Then you can set term bindings and constraint bindings. This can be done on the Definition tab. To set a term binding, select the element that you want to bind to a term. Then, over on the right, select the little Details tab. Towards the bottom is a box, Node meaning in terminologies, containing an empty grid. Click the button in the top row of the grid. This will show a dialog where you can select your binding. To set a constraint binding on a DV_CODED_TEXT, select the text element that you want to bind. Over on the right, select the Terminology radio button. This will display an empty grid down below. Click the [+] button. This will show a dialog where you can add your binding. Does anyone know what the AE does when you enter the interface screen. Is the constraint executed, if not, when is the constraint executed (or is it executed at all?). Term binding constraints aren't executed on the Interface tab. The Interface tab doesn't do anything really. Its only purpose is to give you a bit of an idea of how a hypothetical form based this archetype might look. I never use it myself, but I've noticed that it seems to help some people visualise their archetypes. References to AE user manual is also welcome. Can't find this. Under the Help menu, select Help Topics. This opens up http://www.openehr.org/svn/knowledge_tools_dotnet/TRUNK/ArchetypeEditor/Help/index.html and from there you can follow a link to more detailed help. AE's online help hasn't been revised for more than five years, however. It's out of date in places. For example, it doesn't describe what I've written above, because it was only implemented a year or two ago, but it does describe an alternative way using the Terminology tab. - Peter
