Subject: Re: [soa-rm] Definition(s) of "service"
Joseph: This is why I found Microsoft's definition so interesting: "A software entity whose interactions with other entities are via messages. Note that that a service need not be connected to a network." This implies to me that a service is a service, regardless of whether it is used. I am not agreeing or disagreeing with this, just figured they must have had a similar conversation at some point.
