>> I am having a hard time understanding when the modeller would not know if there was a series of events or not <<
Well for an experienced modeller it is not too hard, although there are still quite a number of grey areas. Heather and I still have discussions and disagreements about the correct Class or use of class attributes. The point is that for beginners or casual users, it *is* hard. Just look at Pablo's or Saso's experience. I want to improve the architecture and, I agree, definitely the tooling, so that people are not forced to think about the hard stuff until they are good and ready or the use-cases emerge, but confident that they are not making a 'wrong' decision which stops their work being shared with a wider community in due course. Pablo's experience is not at all unusual - most groups find it hard to think beyond the boundaries of their own experience, and it is costly to think ahead in terms of design decisions. You forget just how much expertise and detailed consideration that you have given to this problem space. Even with training and experience it will take some time for others to catch up (including myself!). I want people to be able to hit the ground running and not be intimidated by the technology or the ontological philosophy. openEHR does a pretty good job on both counts but I think we can do better. Tooling improvements certainly but tooling is ultimately driven by the RM and based on the experiences of implementation and training over several years I think now is good opportunity to take stock and find some ways of further reducing buy-in without compromising on the excellent work done to date.
