I see your point, Anne. If I properly understood, you confirm the statement of my colleague - RIA is good with fine-grained services.
However, I am confused a little (I am not an expert in REST but know basics). The confusion comes from this logic: if everything in REST is a resource and resource (in REST) has an "interface [the resources it exposes] is fine-grained", then what is the service in REST, especially, coarse-grained one? My understanding of REST is: REST is a concrete communication model between resources; one can read resources as applications. It is a clear alternative to Web Services but we look like agreed that Web Services is not SOA, they might be one of the interface types of a SOA Service. OASIS SOA RM and coming RA recognize that SOA Service may have a business behavior not necessary visible through the service interface. It is not prohibited for a resource having such behavior but with fine-grained interface it becomes less comprehensive and expected than with coarse-grained interface. Thus, to fully understand your response, please, comment on what is a service (coarse-grained service) in REST. - Michael ----- Original Message ---- From: Anne Thomas Manes <[EMAIL PROTECTED]> To: [email protected] Sent: Friday, March 28, 2008 2:23:09 PM Subject: Re: [service-orientated-architecture] Re: Meehan on RIA meets SOA On Wed, Mar 26, 2008 at 3:44 PM, Michael Poulin <[EMAIL PROTECTED] com> wrote: > > One of lead architects around me said that SOA and RIA are almost orthogonal > because RIA demands fine-grained operations while SOA tends to > coarse-grained ones... > > - Michael Hence my assertion that RIA and mashups will become more intimately connected with SOA if/when REST becomes a predominant approach for building services. REST exposes capabilities through a resource interface. (see my recent post, REST is about Resources [http://apsblog. burtongroup. com/2008/ 03/rest-is- about-r.html]). The resource interface is fine-grained. Any "thing" that you want to interact with has a URL. RESTful services are significantly easier to interact with than SOAP APIs, particularly from the RIA and mashup tooling perspective. (Note that the RESTful service can still be coarse-grained -- but the interface [the resources it exposes] is fine-grained. ) Anne > > > ----- Original Message ---- > From: Rob Eamon <[EMAIL PROTECTED] net> > To: service-orientated- architecture@ yahoogroups. com > Sent: Tuesday, March 25, 2008 2:37:30 PM > Subject: [service-orientated -architecture] Re: Meehan on RIA meets SOA > > > > > Why is that?
