SNAP Data Model and Discovery Framework Discussions - Cambridge Meeting Agenda

This agenda outlines the key discussion points for the TIG session in Cambridge on September 28, 2007. Key topics include XML schema mapping, data model structure validation, and strategies for discovery using SNAP services. The session features discussions on participant satisfaction with the data model, future usage of the model for discovery, and the development of SNAP "getData" services. Also discussed are the implementation of the SNAP portal, validation of XML instances, and standards for labeling physical processes. Action items and follow-up on various items are highlighted.

Presentation Transcript

  1. TIG session Cambridge, September 28, 2007

  2. agenda • Igor and Laurent • Franck (maybe) • Gerard: XML schema mapping • Discussions • Data model structure • Validation: instances in XML • Discovery: SxAP or Registry like? • SNAP services: standard and custom • Who, what, when?

  3. Discussion • Q1: How happy are we with the SNAP data model? • TBD update wiki page with (slightly updated) versions • structure (characterisation-like features, semantic vocabularies) • validation: can we describe real simulations (and related products) • Q2: How will we use the model for discovery? • SxAP like (HTTP-GET) • Registry like (more complex support)

  4. Discussion • Q3: What “SNAP”-getData services do we want to predefine? • download, cutout (includes slice), project, virtual telescope (lightcone) • custom • standard API (to be extended)

  5. Action items I • Datamodel (X-mass, 2007) • design: characterisation issues (ML, FB, IC), target object properties, ontology objects (FLeP and standard vocabs, astro journal subject keywords) • XML schema follows from UML (DM WG?) • validation: instances created by RW, IC et al, PM et al, UB et al , GL et al

  6. Action items II • “SNAP portal” implementations (May, 2008) (RW, UB, IC) • accept XML docs • allows browsing/querying/whatever • links to SNAP “getData” services • SNAP “getData” implementations • download and custom only for now • Needs work on document (CG)

  7. Action intems III • Contacts to WGs • DM: framework for XML schema from UML • Semantics: standards for labelling physical processes, object, numerical properties • Registry: tell us how to define our resources, extension schemas (help with implementing SNAP portal?) • Discussions via mailing list !
