Abstract

As individuals and enterprises interconnect via wide area networks, workflows that span them seamlessly will become increasingly valuable. It is likely that heterogeneous participants - humans, applications, organizations - that are physically dispersed over such networks will share workflows that cut across organizational and geographic boundaries. We address the problem of designing a distributed workflow infrastructure that supports such scenarios in the presence of heterogeneous workflow systems and components. We present RainMaker, a workflow framework based on a service requestor/service provider execution model. RainMaker defines a core set of abstract interfaces that can be implemented by distributed workflow components. Together, the RainMaker execution model and interfaces provide a foundation for the interoperability of workflow systems and components.
