Applications Messaging Standard

Dear Apps WG,

One of the first tasks of the Applications working group is to consider how an applications messaging standard may be developed as an IVOA standard. Plastic (see IVOA Note: PLASTIC - a protocol for desktop application interoperability Version 1.00) is a successful protocol which has been adopted by a several VO Applications and there is much interest in having a IVOA standard for semantics and syntax of application messaging.

John Taylor (Royal Obs Edinburgh) and Mike Fitzpatrick (NOAO) have agreed to lead an initial discussion on this mailing list about messaging between VO applications in general.

A proposed work-plan and time line are set out below. This is of course a draft, and is quite ambitious. I would however issue the challenge to have some well developed examples and demos by the May Interop meeting in Beijing.

-Mark.
