Subject: Re: T2 - Assertions and Questions
Date: Tue, 14 Aug 2001 16:41:45 -0400 From: David Smiley <dsmiley@mercator.com> In my mind, the "chasm model" can be broken only under the following condition: Give a use case in which there is an intermediary which cannot be considered to be part of either the From Party or the To Party. More specifically, a use case where the destination for a message specified by the To Party that is not part of the To Party's "business chain", to coin another term. The question of whether there are any such use cases that are part of our requirements, then, is very important: if there are, then Message Services has to go back to knowing about "intermediaries" again. The main benefit of the layering of the "chasm model" was to simplify Message Services by taking out the whole concept of intermediaries. So it's really a question of what use cases are required. -- Dan
