Registry Work Package 02 (Rwp02): Requirements, Science Cases, Use Cases, Test Cases

Contents:

Introduction

This work package was initiated at the Registry Kickoff Meeting (Registry19032003) 19-20 March. Discussion on this work package being held on the mailing list at http://www.ivoa.net/forum/registry/ (registry@ivoa.net)

Members

Members of this WP are MarkAllen, AlbertoMicol, AnitaRichards, KirkBorne, NicholasWalton, RayPlante, ElizabethAuden plus anyone else who would like to volunteer. (Tom Mc Glynn and David Schade mentioned at kickoff meeting)

Scope of Work Package

1. Identify Key Science Cases to be used as drivers for defining registry requirements. These should be illustrative of the range of requests that may be sent to a regsistry.

2. Describe a set of Use Cases, which are representative of envisaged registry usage, and include the use cases required to execute the Key Science Cases.

3. Define a set of actual queries against which registry implementations may be tested.

4. Requirements. Make a set of requirements which are necessary to be able to execute the Use Cases, and will be useful in actual development of registries.

Key Science Cases v0.1 April 11, 2003

Key Science Cases for Registries. 
v0.1 April 11, 2003.

A goal of RWP02 is to identify Key Science Cases to be used 
as drivers for defining registry requirements. These should be 
illustrative of the range of requests that may be sent to a 
registry.

Following a review of the current science cases across the 
various VO initiatives, a 1st draft set of science cases has been 
selected. 

A call for further science cases, and discussion of
other aspects of science cases with respect to registries has
been issued to the Registry mailing list. 

Selected Science Cases:

1.  
AstroGrid: Brown Dwarf Selection
NVO: Select Dwarf Galaxies by Colour for Observational Follow-up
 
Chosen as representative of parameter constrained catalog search
scenarios.

2.
AstroGrid: Deep Field Surveys

Chosen as representative of a data search scenario, with use of
coverage (spatial and temporal) constraints.

3. 
NVO: Gamma Ray Burst +
     Chosen because NVO is planning registry specific developments
     for this science case to turn their GRB demo into a more
     general "show me the sky" tool

4. 
NVO: Find Super Novae Pre-Burst Observation
     Chosen as representative of 'find all data at this point'
     type scenarios. (Perhaps this is the same as the GRB general tool)

5.
AstroVirtel: Luminosity functions of Star Clusters in Nearby Galaxies 
             Chosen because of detailed requirements for registry
             functions.
