Subject: Re: [soa-rm-editors] A (somewhat) radical proposal

I like the emphasis on visibility because it emphasizes the bringing 
together of pieces and the bringing together is more flexible than 
the simple find-bind-execute (e.g. a sample architecture).  In 
combination with establishing the execution context to enable and 
support interaction, it emphasizes the work and information exchange 
that is required for SOA.  Maybe because it hasn't (yet) been 
overused, it seems like less magic than Discovery.  (step 1: need 
miracle; step 2: discover miracle (by making use of core discovery 
miracle); step 3: execute discovered miracle; step 4: be rewarded for 
pressing the need miracle button.  Oops, sorry, that's architecture.)

If we deprecate Discovery, I believe we will need some words in a 
similar vane as we did for loose coupling and coarse-grained.


P.S.  I started Powerpoint doodling while thinking about this and 
came up with the attached.  Worth anything?
