What I am influenced by is what I see in CKM and other repositories. openEHR CKM NEHTA CKM On 18/03/2012 21:00, Sam Heard wrote: Hi This is an interesting discussion. It seems that we might have hit the issue of defining data types independent of a reference model. In a reference model we do want to know that there are a limited set of types (formally expressed) that can be used at any point. I was influenced by the discussion at CIMI that demonstrated this. So the sort of textural elements you have within the datatypes that allow someone to say Autumn for datetime (HumanDate) are probably best dealt with in models where that is appropriate and with a suitable set of terminologies. An uncertain datetime is better for processing than a text (soon after my mother died). There is no doubt about the usefulness of the text, just that it does not belong in a date field. The FHIR may be suitable for messages at this point in time, if so, it is easy to port information to this. Let's keep this thread alive and get a little broader input. Thomas is influenced by Eiffel, Grahame by XML. Most developers will probably sit somewhere in between in terms of requirements for rigor.
