BPEL4Grid Workflow Engine
The BPEL4Grid Workflow Engine is a Grid-enabled Workflow Engine based on ActiveBPEL (see http://www.activebpel.org). It uses the de-facto industry standard BPEL (Business Process Execution Language) as workflow/process description language.
The engine fully supports the BPEL 1.1 standard and has been extended by Grid-related features like support for Web Services Resource Framework (WS-RF) and Grid Security Infrastructure (GSI). It is able to invoke both Grid and Web Services, encrypt and sign messages and delegate credentials. It furthermore monitors the lifetime of proxy certificates and -- by integration with MyProxy Credential Management Service -- is able to automatically renew proxy certificates during the execution of a workflow.
To allow convenient and time-saving workflow/process modelling, we have also developed a graphical workflow designer based on Eclipse. The Visual Grid Orchestrator (ViGO) is described and available for download here.
