Early Modeling from the NVO

• Some early requirements
• Some early use cases:
  • 3 use cases from Niall Gaffney.
  • Catagorized Use Cases from Ray Plante.
  • 3 use cases from TomMcGlynn.
  • Consider the case of a resource having many collections to register: see Tom's discussion of the Vizier case
• Resource Metadata Note: Deprecated by later versions listed in RWP03Specs
  • VOResource
    • based on RSM (V0.6) document by Hanisch et al.
    • Prototype version: VOResource.xsd
    • an example instantiation: adil.xml
    • Comments and illuminating figures

Note that the above Schema is under development and changes often. More stable versions should appear under the Specifications section below.

• Space-Time Metadata
  • Arnold's Space-Time Coordinates page describes the current model and includes a link to a DTD.
  • The current version of the regions schema can be seen as a DTD.

Early Modeling by the AstroGrid Project:

• some baseline schemas broken down into 6 sets: Registry, Service, workspaceService, dataService, processingService, registryService, serviceLocation.
• some suggested amendments to the baseline proposal.
