Idempotent Capability – new pattern description published

A new and improved description of the Idempotent Capability pattern has just been published @ soapatterns.org. The pattern explains why idempotency is important as well as why and how a non-idempotent capability can be transformed into an idempotent capability.

Many thanks to my co-contributor Cesare Pautasso as well as rewievers Radovan Janecek, Ian Robinson and Nicolai Josuttis.

Joe McKendrick, that I’ve had the pleasure of working with on several occasions, created a new word a few years back. He called it JBOWS.

Joe correctly identified some big gaps in the application of service-orientation in the new so called services and architectures of services that were to take companies closer to the holy grail called SOA

Web Services was seen as an almost failsafe path to salvation, and everybody was doing it. The problem was that while everybody was focusing on the new hot and cool technology called Web Services they forgot the really important things namely
