Re: purpose/goals for observations ontologies

Well, the use cases are quite extensive, but I am confident they will  
never be exhaustive. But the problem (as you suggest) will be that 100  
use cases serve no evaluative purpose, as they will include almost any  
requirement and demand every conceivable entity.

The use cases will have to be refined and prioritized (and a fair  
number excluded, is my guess) if they are to be the basis of our  
determination of what to include or not include in the model.

Unfortunately, that is "real work" that could easily take the rest of  
the year.  So it seems to me we have an impasse.
