GUI-directives/hints again (Was: Developing usable GUIs)
Hi Koray, I agree with Thomas here, Koray, but I take your point about the separation into a further layer represents added potential development complexity. I think we should expect tools to handle this in the same way that a complex development environment like Visual Studio handles various layers of application 'code' and resources within a seamless environment. You should not have to think about these separate layers during development. Your comments about 'isCoreConcept' are very interesting because I think you have touched upon an issue in semantics that we are coming across, particularly when modelling detailed clinical findings. I had been thinking about the same issue from a different angle, essentially how to cleanly model findings where the requirement might expand gradually from a Y/N response to a full blown complex structure, in different clinical contexts and over time as more detailed requirements emerge. It touches upon the crucial areas of integration with SNOMED post-coordinations and the handling of Questionnaire type structures but I think we should continue this discussion is a separate clinical thread because it is definitely not just an issue of GUI.

I have explained my reasoning in a previous message but shortly archetypes and templates are all about information capture and validation (i.e. which data items, their organisation, and basic constraints for validation). Real world semantics are delegated to terminology (i.e. heart murmur IS-A symptom of heart disease or cardia is PART-OF stomach etc). I think we need to keep archetypes fairly pure and generic with large scale interoperability in mind. However templates provide all the convenience needed otherwise. I strongly believe we do_not_need another layer of modelling for GUI because referring back to my definition of clinical models, these are to do with information capture and validation... Only one problem with this reasoning: templates are often used for things other than the GUI, e.g. messages. In the future, they will end up being used for reports as well. In general, I believe the openEHR template will be an artefact defining a specific data set (including optionality where needed), and auxiliary artefacts will always be needed to connect that definition to its target technology: a specific kind of GUI form, message infrastructure or relational mapping or querying environment - thomas ___ openEHR-technical mailing list openEHR-technical at openehr.org http://lists.chime.ucl.ac.uk/mailman/listinfo/openehr-technical

Where a concept is needed you have two choices: * A) mix it in with the languages architectural layers you already have * B) create a dedicated layer or component type, and possibly dedicated formalism if needed A) represents the history of large scale systems built in the 60s, 70s and 80s - unmaintainable spaghetti. B), if done right is always better.

I agree with your comment, but only for v1.5 templates and archetypes. For v1.4 I think that GUI Templates must reference archetypes ids and paths. -- Kind regards, A/C Pablo Pazos Guti?rrez LinkedIn: http://uy.linkedin.com/in/pablopazosgutierrez Blog: http://informatica-medica.blogspot.com/ Twitter: http://twitter.com/ppazos Date: Wed, 8 Dec 2010 15:41:11 + From: thomas.be...@oceaninformatics.com To: openehr-technical at openehr.org Subject: Re: GUI-directives/hints again (Was: Developing usable GUIs) On 08/12/2010 15:26, pablo pazos wrote: May be if we change the terminology to GUI Templates and openEHR Templates, we will not have these problems.

Hi Pablo, In both ADL1.4 and 1.5 every path is still an archetype-based path. The proposed schema for an operational template is very similar to the XML schema of an individual archetype but obviously includes multiple aggregated archetypes and omits any nodes which are constrained out. Templates are technically identical to specialised archetypes. The difference is that specialised archetypes support templating features such as constraining out unwanted elements and aggregating archetypes. The only difference between an archetype and a template is that new content i.e. new nodes or terms cannot be added to a template.
