certainly I agree with that - it is just that using a 'white-box' method is unlikely to work in my view; a 'black-box' method is more useful because it tests the information model(s) against their ability to support real world content models like archetypes. I am not saying that the openEHR model is perfect by any means, only that much of it was elaborated by direct archetype modelling; this provided far more feedback for changes than any standard IT modelling methods or metrics could ever ave done. As I think I mentioned in the blog post, one of the best tests for an information model in e-health is to see how you would model Glucose Tolerance Test based on it. With some it is exceedingly difficult, with some it is easy. - thomas > It would be the quantification of the suitability of "...[a thoery] that > is as simple as possible for the most comprehensive explanatory power." > > Anyway, i might put together something more specific about this and > share it with the list sometime later, although i admit that there are > still some gray areas especially when trying to provide some practical > examples on established models. > > All the best > Athanasios Anastasiou > * * -------------- next part -------------- An HTML attachment was scrubbed...
