We are working on some fairly large scale integration at work.
As you might expect, we are trying to not hurt the web.
As most older "enterprises", we have many many aging systems. But the "domains" or large groupings of our systems are well known & shouldn't change too much over the next 10-20 years.
I'd rather bet on the URI than any ESB vendor.
I started working on a naming scheme for our cool URIs today. I think that if we get that right, we'll be heroes.
With a URI naming scheme that doesn't change you get a very different, very simple view of your systems. Sure, there may be madness today behind those URIs, but over time that madness will hopefully start to go away. But your URIs will stay the same. A simple vaneer on madness that slowly becomes sane. Yay Cool URIs that don't change.
