Joint IVOA - GGF (Astro-RG) WorkShop (1/4)
Nicholas A Walton, IoA, Univ of Cambridge, UK(Co-Chair Astro-RG) (+ see below in other comments)
This one day workshop jointly sponsored by the GGF (astro-RG and related groups) and the International Virtual Observatory Alliance (http://www.ivoa.net) will address areas where the global virtual observatory is deploying an operational distributed data access and manipulation system, utilising, where appropriate standards developed in the context of the GGF. the workshop will look at areas of success and areas where additional astronomy domain specific issues have required a non-standard approach.
This workshop is 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 for 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.
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
- 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
