Scope and Content

Workflow is a critical part of the emerging Grid Computing Environments
and captures the linkage of constituent services together in a
hierarchical fashion to build larger composite services. Workflow 
captures "programming the Grid" and encompasses a broad range of 
approaches with names like "Service Orchestration", "Service or Process 
Coordination", "Service Conversation", "Web or Grid Scripting", 
"Application Integration", or "Software Bus". One can identify at least 
four important aspects of workflow

User Environments or Workflow IDE (Integrated Development Environment)
Representation and language to express workflow
Translation or compilation
Execution & runtime support.
Workflow overlaps with areas such as "distributed system programming" and
"virtual data management".

This workshop will build on two related workshops in this area

GGF9 Life Sciences workshop
UK e-Science December 2003 workshop at Edinburgh

The first was focused on identifying key requirements for Life Science
Grids while the second is focused primarily on the e-Science UK effort.

We suggest that workflow is a relatively immature field and it is
necessary to gain experience with several different approaches to 
several different applications. One goal of the GGF10 workshop will be 
to collect a set of exemplar applications and their requirements 
generalizing the Life Science meeting which is gathering requirements in 
their application area.

The workshop will be organized as four panels.  A coordinator for each
panel will begin the discussion by raising the important issues and
questions that the panelists have addressed. Each panel will have three 
or four participants who will each have approximately 15 to 20 minutes 
for presentations and answers to the panel coordinators questions.

Applications  A study of the differences and similarities of Grid
applications as seen from the perspective of workflow execution.
Coordinator:   Virinder Batra  (batra@us.ibm.com)

Workflow Architecture and Surveys  A broad look at workflow 
technologies and methods, semantic grid implications and reports from 
other meetings
Coordinator:   Carle Goble (carole@cs.man.ac.uk)

User Tools & Languages  What are our experiences with different
programming languages for Grid workflow? How can an application 
scientist describe workflow in simple graphical terms?  What tools make 
it easy for users to execute workflow without becoming programmers?
Coordinator:   David Berry (daveb@nesc.ac.uk)

Workflow Execution and Runtime Considerations  What are the appropriate
execution models for Grid workflow?  How does this differ from 
commercial workflow execution?  What Web and Grid Services are required 
for reliable robust workflow execution?
Coordinator:  Ewa Deelman (deelman@ISI.EDU)

The meeting and panel conclusions will be summarized in a GGF
informational document. Speakers will be invited to submit a paper for a
Special Issue of Concurrency&Computation: Practice&Experience.

How To Participate

An extended abstract relating to one of the for panel themes above 
should be sent to the panel chair or to gannon@cs.indiana.edu. 
Solicited papers can cover any of the following topics:

1)      A detailed workflow use-case based on real grid experience

2)      New workflow specification languages targeting grid applications.

3)      Workflow execution engines that interoperate with grid services.

4)      Grid services that support workflow execution.

5)      Specialized tools for managing Grid worflow.

The extended abstract can take the form of a position paper or short 
paper and it should be no more than 8 pages in length not counting 

The dates are
