Description
Summary:Although conceived for web services, it is shown how B pel (Business Process Execution Language) can be used to orchestrate a collection of grid services. This is achieved using the technique of C ress (Communication Representation Employing Systematic Specification) to describe the composition of grid services. C ress descriptions are automatically translated into L otos (Language Of Temporal Ordering Specification), allowing systematic checks for interoperability and logical errors prior to implementation. M ustard (Multiple-Use Scenario Test and Refusal Description) is used to validate the generated specification against use case scenarios. The same C ress descriptions are then automatically converted into B pel/W sdl code for practical realisation of the composed services. Grid services are executed by Globus Toolkit 4, while their orchestration is supported by the ActiveB pel engine. The M ustard scenarios are used again to evaluate the implementation. The overall approach therefore supports rigorous development and automated creation of orchestrated grid services.
