One of the important reasons we use Eiffel at all is that it gives us a
modelling framework closer to UML than any other language, while at the
same time giving us compilable software directly, without having to
translate into something else. The alternative would be to do UML models
in Rose or Together (or some other tool I don't know about) and
translate into a language like Java or C++. AFAIK, none of the case
tools yet include OCL, which Eiffel effectively does; nor are their
translations to the languages 100% reliable. And in any case, for Java,
you have to forget using contracts or generic classes. Overall, not a
very attractive option.With Eiffel, we can do it all in one go, and
since it is easy to read Eiffel, we find that clinical people can easily
review models.

And as some of you know, there is some convergence work happening
between current efforts in modelling and implementation, namely GEHR
(Australia), SynEx (UCL), the CEN 13606 standard. HL7v3 is also being
used as a resource, although its purpose and form are further away from
EHR-flavoured approaches. We hope to make material progress in this area
by the end of this year.
