Re: [soa-rm-ra] Views and viewpoints

Yes, this makes sense because you pick or design your viewpoint to satisfy what the view is supposed to cover. If you need another viewpoint, you are defining another view. OTOH, I could pick a bunch of DODAF artifacts as my viewpoint and, if it works, it is certainly reusable.

Ken,

I think you've captured the fundamental difference between view and viewpoint quite nicely so, yes, this is reasonable.

I would only add that although the relationship between views and viewpoints (within a given architectural description) is one-to-one, as noted in the 1471, a view should correspond to only one viewpoint, otherwise it is considered redundant. A viewpoint, on the other hand, can have more than one view. This is analogous to the class : object relationship in OO parlance, but I wouldn't take that analogy too far.

Cheers...
