Agenda bashing: the audience agrees with the agenda

1. Reagan Moore gives his presentation
--------------------------------------

   Slides will be put on the APPS-RG web site

   Motivation for grid usage
   4 use cases discussed
   IPAC
     -- data intensive computing
     -- problems with 

   Questions posed by Reagan Moore:

   Q1: Which capabiltes is this group going to identify with?
   Q2. How do we go from service that allow remote job invocation that allow
       virtualization?

   The audience discussed various aspects of large (peta byte) data-based
   applications.

2. Report from the APPS-RG/PGS-RG workshop at GGF14
---------------------------------------------------

   David Wallom, University of Oxford, UK

   David reports from last GGF's workshop, mentions the upcoming

------------------------------------------------------------------
                    and deployment?
                    ---------------

   As the audience consists only of well-known people 
   (within the APPS group), the open microphone and discussion was skipped.


4. Future (activities) of APPS-RG
---------------------------------

Thilo recaptures the group's charter as of fall 2004.

[cite charter:]
Goals:
- Provide a forum for reporting upon application's use of grid technology
  and identifying gaps between what was desired and what was provided in
  the underlying grid technology.
- Provide a forum for reporting upon services that are maturing and can
  support complex applications.
- Provide a forum for the cross-fertilization of the exploitation of grid
  technologies across a spectrum of domains.
- Provide a forum for developing and presenting case studies for
  applications that represent good examples of the types that utilize the
  integration and composition of services.

Milestones:
- Organize from one to three grid application workshops per year...
- Dedicate a portion of ...[an] APPS-RG meeting to a birds-of-a-feather
  period... to facilitate additional off-line discussions...

Thilo explains that a merger with UPDT-RG had been discussed.
Due to low interest, UPDT-RG will likely been closed.
APPS-RG will extend its interpretation of its chartered focus to cover
also tool-related issues of application development.

Reorganization of GGF, addition of a "Community Function"
The new community function has similar aims as APPS-RG has had for years
now. The question is raised whether this means APPS-RG can declare "success"
and disappear or alternatively, what are the new circumstances under which
to continue?

discussion:


  Laura McInnis (LM): Apps-RG should stay, maybe compute-apps and data-apps?
  Wallom: entertainment industry, rather than focus on "technology"
  

What is the difference between community track and APPS group?

akin to PGS is the watchdog group for mgmt issues
APPS should be the watchdog group from where discussions should flower.....

Q: Should the GGF Use Case Repository be an activity of APPS?
A: not clear

Q: Should we go into Suspended Animation? 
A: no	

Q: is the defn of UC the same as that used in SW technologies ?
   or are they "this is what happens" ? 

   Andre Merzky (AM): OGSA is more industry 
       others are more general

   Q: in order to represent end-user community should they become
      more formal e.g. UML


  AM: Use Case Repository. GGF is getting one. 
      as it is difficult to find anything...
      Could this group 

  Jha:  a) purely editing? little value added?
        b) too broad a scope
   

  Laura: Lets ask people on the mailing list: what should the identity
  of the group be?

  Thilo: Should we be meeting in the community track? or continuity in
  the standards track?

  Then we should make "these" (group) meetings a "house-keeping".

Finally, the future direction of APPS-RG needs intensive discussion, both
with the group (mailing list) and between the chairs and GFSG.


15:45 the session was closed
