Workflow Suite
• Generic Service Toolkit
–
–
–
–
Tool to wrap command-line applications as web services
Handles file staging & job submissions
Extensible runtime for security, resource brokering & urgent computing
Generic Factory service for on-demand creation of application services
• XRegistry
– Information repository for the OGCE workflow suite
– Register, search, retrieve & share XML documents
– User & hierarchical group based authorization
• XBaya
– GUI based tool to compose & monitor workflows
– Extensible support for compiler plug-ins like BPEL & Jython
