Re: [service-orientated-architecture] if f(x) changes, do you version the service?

[Stanley Stanev]

I think that as soon as the SLAs and contracts (think WSDLs) do not change then no need of a new version of the service. Very general interfaces could be a problem the same as very open contracts in life are :) thanks, Stanimir Stanev (Stanley) MomentumSI Mark Baker wrote: Radovan - I think you and I agreed to disagree long ago on whether or not the data format constituted part of the interface. That said, I agree it's valuable to not change even the data format in a non-compatible way. My switch to Atom was felt to be a compatible change because I waited until most RSS consuming applications also supported Atom. I never heard a single complaint. Mark.

It's likely that, at some point, a service evolves in such a way that requires interface change. It's not a failure, it's life. Otherwise, RSS evolution is a failure or HTML evolution is a failure - just to name few ;-) > > I would be interested in whether your 'maximum amount' means 'all' or 'a lot'? Btw, didn't you announce some time ago you are switching only to Atom? Didn't your blog's interface change then? > > Cheers, > Radovan > > On 9/29/06, Mark Baker <[EMAIL PROTECTED]org> wrote: > > > > On 9/28/06, Michael Poulin <[EMAIL PROTECTED]com> wrote: > > > > > > Mark wrote: " Never." > > > May I ask: why? > > > > Because I always endeavour to maximize loose coupling by separating > > the concerns of implementation from the concerns of interface.
