ROSE: A transactional services coordination engine
Victor Hernandez-Baruch, Alberto Portilla, José-Luis Zechinelli-Martini · 2007
This paper introduces an adaptable transactional services coordination engine called ROSE. Different to existing services coordination engines, ROSE is able to combine different transactional contracts for executing a given coordination. Contracts capture application requirements as transactional properties derived from business rules. Inspired on separation of concerns approaches, our engine uses the notion of contract for expressing transactional properties separately from coordination specifications. In this way contracts can be defined and modified without modifying the coordination. The current version of ROSE is implemented on top of the open source coordination engine Bonita (www.objectweb.org) and it implements atomicity contracts useful for e-commerce applications.
