But don't forget that the RM has its own semantics as well - it depends on what you are doing. If you are graphing a blood pressure History then you will of course use some of the logic of History, Event etc. Similarly for Instruction/Activity and so on.
But it is the archetypes that provide 80% of the domain-level semantic checking. - thomas > ------------------------------------------------------------------------ > Rodrigo Filgueira > Asistente Docente/Investigador > N?cleo de Ingenier?a Biom?dica, FING - UDELAR > > > Thomas Beale wrote: >> Rodrigo Filgueira wrote: >>> I've been going round in circles about this question all weekend, >>> and have two ideas. >>> >>> 1.
