Its one of those interesting bits how old approaches suddenly become "required" for SOA. The paper proposes a top down process decomposition approach (which has several issues in my experience) and a bottom up (from technology) discovery of services than then "meld" together. In reality therefore this is a Process Oriented Architecture (as it places process as the important entity) and then use a technology driven approach to define services. This makes three big assumptions 1) That process can be used to describe everything in an enterprise (it can't) 2) That the existing estate is the best place to start when considering your service model (it isn't) 3) That WS-* = SOA (it doesn't) It would be great if, for once, a vendor took a big step back and thought "hang on this SOA stuff is a new way of looking at business and IT, so maybe that means more than just re-badging our existing product and claiming its a pre-req for decent SOA" That is one reason I bother with the REST arguments I have (and am learning from) as they are trying to do something different. > or join our online seminar here: > > http://www.ids-scheer.com/sixcms/detail.php?template=seminars_en > > Regards, > > Sebastian >
