Both Thomas and I have been rather resource-constrained and time-challenged. I agree that working together will be a good idea. > Otherwise, tell me the difference! One difference is that GEHR has decided to use Eiffel. The GEHR team questions whether GEHR should be implemented with Zope/Python, Java, etc. OIO is currently implemented with Zope/Python/SQL. I am pretty sure that OIO can also be implemented with Java, Eiffel, C, Perl, etc. GEHR/OpenEHR is perceived to be "great technology but a few years away". OIO has been in use for 2 years and *I think* is functionally quite close to a GEHR kernel. We even have an online metadata repository running for over a year now (OIO Library). > Do you have a similar Paper for me to read? No, Thomas has a great paper. There is no point for me to write a "similar" paper. Perhaps it should also work the other way around :-). > Is there a description of OIO models (UML)? No UML but the model is rather simple-minded and have been described a few times (=form contains question item(s) which use one response/itemtype with a specified action). > I'm not good in Python syntax and don't want to read through source > files to catch your models. No need to do that. The OIO architecture is described in several presentations at www.TxOutcome.Org and in documentation files that are also online. You can also browse the forms available in the OIO Library and download them as XML document. If you do that, you will see how simple the forms schema (metamodel) is. > All I've seen from OIO is some web interfaces. Right. The web-interface is what makes the system usable by clinicians and researchers. You are probably more interested in looking at the schema and examining the metamodel.
