Announcement about Workflow future plans

[Andre Schaaff]

Dear all,

As you know we will soon be facing a new generation of facilities and 
archives dealing with huge amounts of data (ALMA, LSST, panSTARRS, 
LOFAR, SKA pathfinders,..) where scientific Workflows will play an 
important role in the working methodology of astronomers.  A detailed 
analysis about the state of the art of workflows in the frame of the VO 
involves languages, design tools, execution engines, use cases, etc. A 
major topic is also the preservation of the workflows and the capability 
to replay a workflow several years after its design and implementation. 
Several talks concerning these issues have been presented during the 
past IVOA Interop meetings (see references below).

In order to undertake this task within our community we think that as a 
first step a Note should be written. Participation is welcome, in 
particular, we would like to collect experiences (including use cases, 
tools, etc.), references, remarks, etc. We plan the Note to be published 
around September and discussed at the Pune Interop meeting. We should 
then decide on starting a working draft describing those aspects and 
possibly in a new Interest Group on Workflows.

Best regards,


André Schaaff and Jose Enrique Ruiz
