Last week IBM and Ford made an important announcement about the release of the Reliable Asynchronous Messaging Profile. Chris Ferris has all the details in his blog entry and linked article. Here's a bit from the top of the article:
The Reliable Asynchronous Messaging Profile (RAMP) 1.0 is a profile, in the fashion of the WS-I profiles, that enables, among other things, basic B2B integration scenarios using Web services technologies. This profile is the second public draft of what was formerly labeled the IBM Basic B2B Profile. The motivation for renaming the profile was based on feedback from analysts, our customers, and partners stating that the profile had relevance beyond business-to-business scenarios and that the name should be changed to reflect this fact.
