Perhaps this is a use case where aliases could help. I remember making this same argument for a term many years ago, and being told the reason for using the semantically modeled term is that *everyone else* who isn't in the field will recognize it.
Wouldn't it be the best of both worlds if both the semantic term, and the domain-familiar term, could be considered acceptable? I think that sound I heard may have been glass shattering from the collective CF shriek. :-) John On Jan 20, 2015, at 10:50, Lowry, Roy K. <[email protected]> wrote: > Hi Nan, > > I must admit a little discomfort watching the process of CF semantic > modelling replacing a well-known term with something that nobody in the > domain would recognise without significant education.
