Nic, This looks excellent. There is now, however, a web site where this can eventually be uploaded. Real soon now, this URL should be available for GGF-17: http://www.ggf.org/ggf_events_communityInvolvmentProposal.htm but it is not at this moment. --Craig At 01:52 PM 2/22/2006, Nicholas Walton wrote:

Dear Craig

we in Astro-RG and the IVOA (see http://www.ivoa.net) would like to propose organising a one-day workshop at GGF17 in Tokyo. We have put together our proposal, and would be pleased to know whether this is acceptable.

If there is any more infomation that you require, please let us know.

Yours,

Nic Walton (co-chair GGF Astro-RG) (secretary IVOA)

D) Scope and Content (a paragraph or two of the workshop description to be put on the program.

This workshop, jointly sponsored by the GGF and the International Virtual Observatory Alliance (IVOA - see http://www.ivoa.net). The meeting is timely in that the global Virtual Observatory (VO) projects are now deploying systems worldwide for operational and scientific use, where use of emerging GGF standards in or instance data management and security may have a vital role to play. Interoperability with existing grid infrastructures (e.g. TeraGrid, EGEE) is also a key topic, since VO centers or users must be allowed to take advantage of the power offered by computational grids. This meeting preceeds the next major IVOA interoperability workshop to be held in Victoria, Canada (15-19 May 2006).

The programme would address issues of common interest to the GGF and the IVOA focusing on how a Global Virtual Observatory is being constructed using domain developed high level interoperability standards, but utilising lower level grid and grid service standards and concepts where relevant.

The workshop will provide an opportunity for those involved in creating the interoperabilty standards required by the global Vrtual Observatory community to interact with those creating generic grid standards. The feedback from the exemplar science domain will highlight the opportunities and difficulties presented by take up of GGF standard compliant implementations.

E) Programme

We envisage that the meeting would be a 'Type two (refereed workshop)' - with a call for papers.

The programme would address in 8 ~one hour sessions, the following areas:

1) Requirements for a Virtual Observatory: the Domain Perspective - Science drivers for a Virtual Observatory (Walton) - Capturing user needs from a middleware perspective (Newhouse)

2) VO Case Studies - Example VO implementations, UK, USA, Japan, etc - Experience with existing grid infrastructures

3) Registries and Resource Discovery

4) Data Management - including preservation of data and knowledge

5) Application Environments

6) Astronomical Workflows

7) Security - authroisation and authentication

8) The Production Virtual Observatory - logging and debugging - training and support - account management - software licensing

Each session would include a period for open discussion

F) Past History of hosting a similar workshop inside or outside GGF.

The co-organisers have organised a number of successful workshops at previous workshops including most recently the 'Workshop on Grid Applications: from Early Adopters to Mainstream Users, Jun 2005).

The IVOA regularly hold technical workshops - see www.ivoa.net

G) Duration of workshop

One full day - to be held in Tokyo at GGF17 (May 2006). The venue could be either the National Astronomical Observatory of Japan, or at the GGF.

H) Estimated # of participants

50+ attendees would be expected.

I) Publication Plans --- please indicate if you have plan to publish the workshop result with a certain publisher. If left out we will assume that the workshop product will be a GGF Informational Document.

The meeting would be published as a GGF informational document.
