System and method for orchestrating composite web services in constrained data flow environments
First Claim
1. A system for orchestrating composite web services in a constrained data flow environment, said system comprising:
- a build time module comprising logic circuitry adapted to;
receive a composite web service specification;
partition said composite web service specification into multiple topologies, wherein each topology comprises a set of composite web service partitions that are communicatively connected with each other at runtime, and wherein each composite web service partition comprises a functionally complete composite web service; and
select a topology for deployment;
at least one runtime module comprising logic circuitry adapted to verify and deploy partitions of the selected topology within a corresponding component web service domain.

Abstract
A technique for orchestrating composite web services in a constrained data flow environment. Data flow constraints represent the restrictions which the domains involved in composition might want to impose on access to the data they provide or the source from which they can accept data. The data flow constraints are overcome by breaking down an input composite web service specification into topologies (a topology is a set of partitions communicatively connected with one another at runtime). The system applies a rule-based filtering mechanism to choose a topology that does not violate any data flow constraints. Each of the partitions belonging to the chosen topology is executed within the same domain as the corresponding web service it invokes, thus having the same access rights as the corresponding web service. The composite web service is orchestrated in a decentralized fashion using these partitions, thereby ensuring that no data flow constraints are violated.
