Charter

• Focus/Purpose explore, evaluate and propose
  workflow representation and mapping techniques
  that enable the high-level description of
  application workflows and their execution in the
  Grid environment. An area of emphasis will be on
  scientific workflows, which describe the behavior
  of complex applications. ..
• We will investigate workflow issues as they
  pertain to the entire workflow lifecycle, from
  initial formation, ., to tracking the progress
  of a complex workflow through to execution,
  including refinement and repair.

Charter contd

• Scope We will identify existing technologies
  as well as open issues that pertain to the entire
  workflow lifecycle.
• Although one focus of the group is on scientific
  workflows, business workflows are also within the
  scope.
• Where appropriate, the research group may spin
  off working groups.
• Proposed tasks
• Provide a forum to discuss and share best
  practice in projects that use workflows to
  represent complex applications.
• Track workflow activities within W3C and inform
  the Grid community on what tools and ideas are
  relevant in the Grid environment.
• Evaluate the applicability of web services
  coordination to grid services.track WSRF
• Explore various existing technologies applicable
  to workflow management.
• Identify the open issues in the area.

Charter Contd

• Goals
• The goal of the group is to foster the exchange
  of ideas, to explore various aspects of workflow
  management in Grids. As such we propose to a
  series of topical discussions and presentations
  and to generate reports reflecting the issues
  discussed during the meetings.
• Address the following topics in consecutive GGFs
• Workflow Specification Languages and Tools
• Business and Science Workflows in the Grid
  Environment.
• Workflow Management Research in Web Services and
  Applicability to Grid Services
• Workflow Execution Systems in Grids
• Fault Management in Workflow Execution
• Taxonomy of Workflow Issues and Systems
• Exit Strategy
• The ultimate goal of this group is to construct a
  taxonomy of workflow issues and systems. Given
  that workflow management is just beginning to be
  addressed in Grids, this research group may
  extend beyond the 2 year limit.
