DS4 Scope

This task will produce designs and prototypes for new VO-compliant end-user tools. We will produce a list of suggested priority tools. This will partially be based on the experience and feedback of precursor projects and will be based on input from the scientific user community.

Work will be conducted in close collaboration with data providers, e.g., members of the Data Centre Alliance, current and future missions, simulations as well as tool builders. A goal is to help existing facilities with technology take-up and to have a lasting impact on Astronomy data centres and their user community by exploring new designs and deriving generalized IVOA standards.

Workshop Tutorial

• H/W & S/W setup• public demo server (ESO, others?): Astrogrid portal, MySpace, experimental registry, ...

• improving usability of AG portal for end users and DCs:• security review• ivo:// address exchange layer (MySpace, etc.)• multiple filestore support• MIME-type association

• use cases for browsing survey & archival data:• preparing test sets of survey data for sample services • support of graphic previews (.jpg, .png)• footprint overplotting capability

Derived FocusIterations 2-6

Iteration Instr Focus Remarks

1 T8/9 Portalbrush up of workflow env.;add footprint plotting capability

2 T1 multi-waveband image tool important for PR and demos3 T7 generic source extractor prerequisite for SED builder4 T4 cross matcher prerequisite for SED builder5 T3 SED builder prerequisite for fitting6 T2 fitting and classification tool ... at last

Note taken during the presentation: • The group concluded to initially focus on T4 ‚cross matcher‘.

• Work on an iteraion‘s focus area does not prevent work in any other area. • Above list is ‚a‘ possibility; feedback requested from DS4 partners.
