Subject: Re: [soa-rm] eCommerce definitions
More than 20 years ago, Tony Hoare go this one nailed down. In his book Communicating Sequential Processes, he talks about a rendezvous between processes, rather than sending messages. He correctly (IMO) identified that the critical concept is one of two threads of activity coming to a mutual understanding of a common event. This is also a nice way of thinking about service consumers interacting with a service -- a rendezvous is inherently more neutral than using a service, offering a service etc. etc. Frank On Apr 15, 2005, at 5:54 AM, Anders W.
