Hi Thomas, I thought all archetypes must conform to a standard GEHR Object Model (GOM)? In response to my previous posting (excerpt from http://www.mail-archive.com/[email protected]/msg03196.html), I said: >*Any "idealized" schema is arbitrary (in the sense that it cannot be proven to be >objectively ideal) and necessarily functions as a constraint upon the actual schema.* You said: Philosophically this might be true, but we can perform just good information analysis and come up with some kind of useful standard schema. This is effectively what things like the RIM, GEHR Object Model, CORBAmed interface etc are. >Compositions mostly correspond to particular >usages, processes, contexts etc, so there is no getting out of creating various >archetypes each containing some of the same terms. But if all the archetypes must conform to GOM, then how can they not all be simply subsets of GOM? What if a concept is new and is not mapped by GOM? How can GOM be extended? Who should decide? Once you have a GOM that constrains archetypes, it seems that you inherit all the features (good and bad) of a "idealized schema". ... >> be possible to take data generated by one scheme and to group it (m to 1) to >> meet another requirement.

Interesting! Does that mean you will end up with a giant tree of archetypes? Kind of like Philippe's Odyssee semantic network? Would each node/leaf be an archetype or a concept (since each archetype may contain more than one concept)? How is that better than having a large set of "archetype-to-archetype" translators?
