JSDL Extension for Tasks Workflow Representation of Execution in Distributed Systems

Defining a standardized task description language makes interoperability between different systems for job management easier and also facilitates one language's translation to another. This paper analyzes several task description languages and proposes a JSDL extension based on the observation that JSDL describes only the submission requirements of jobs. The extension contains all necessary information regarding one job's requirements in its entire lifecycle. The extension adds information about the job's owner, the execution requirements and also data related to dependencies between job and data transfer conditions. As JSDL, the extension specification uses a number of normative XML schema.
