*Afternoon Session, Tuesday May 25, 2004*

---++ Overview

This will be the first meeting for the Applications Interest
Group.  The role of this group is to make sure that members of the 
VO community are aware of the applications that all of us are
developing and to ensure that we can pass on the lessons we have
each learned in writing VO tools.

This session will consist of three parts.  The first few minutes
will be spent introducing the members to each other and reviewing
the proposed charter for the group and how we anticipate using the
Twiki and E-mail facilities.  This is basically a brief business
meeting for the interest group.

The second part of the meeting is intended to allow developers to
briefly describe and demonstrate the VO tools that are now available.
The presentations should include the capabilities provided to the
users, how VO techologies, protocols, etc are used (or not used!)
within the tool, and if the tools might be useful as a component
in some larger VO application.  In addition to stand-alone tools,
presenters may wish to talk about libraries for implementing
VO capabilities.  In particular, a comparison of the capabilities
and reach of the various VOTable libraries is included.

The remainder of the afternoon is a discussion of what we have learned
in building these tools and libraries.  Are the existing VO
formats/protocols useful?  How can they be improved?  Are there
elements in a VO infrastructure that would help in building and
delivering applications?  A roadmap for this discussion
is suggested in the agenda, but participants should feel
free to bring up the topics they deem most important.  The sense
of this discussion will be reported back to the meeting as a whole
in the plenary session.
