  2. Theory in the VO: the present GOAL: define standards to publish, search and access theoretical data TARGET DATA: produced by numerical calculations: Simulation results - raw, “Level-0” data - Post-processing, Level-1 products (halo catalogues, theoretical spectra…) - Synthetic observations Level-2 products (virtual telescope…) - Analysis Level-3 results (correlation functions, power spectra…) • SPECIFIC FOCUS: LARGE simulations and post-processing products • 3+1D, spatial/temporal • “micro-physics” simulations (under discussion) PRESENTED WORK: prototype implementations of: SimDB – Simulated data model (describe and search, advanced development stage) SimDAP – Data access protocol (select and get, work in progress) Tools for the TVO (S3 Wizard for microsims, VisIVO for visualization)

  3. It’s too large !!! Metadata VOTable I like this one Search for simulations with Lambda>0.7 Binary data file Let’s select a sub-region!!! Perform the analysis on-site Finally I have a jpeg… cannot be too large!!! Extract a sub region… it is still large Data is too large!!! The basic idea

  4. TVO: path forward • In the next months: • Complete the SimDB data model • Complete the SimDAP access protocol • Develop, standardize and deploy existing protoype services: • CNRS • GalMER • ITVO • Trieste: http://wwwas.oats.inaf.it/IA2/ITVO • Catania: http://itvo.oact.inaf.it • Under development • SimCat (UCSD) • PDR/SimDB (Paris) • Horizon/GalICS (Lyon) • GAVO (hydro simulations) • Develop TVO compliant tools (e.g. VisIVO Server) for advanced services. • Special thanks to • Ugo Becciani • Laurent Bourges • Igor Chillingarian • Norman Gray • Gerard Lemson • Franck LePetit • Mireille Louys • Patrizia Manzato • Rick Wagner • Hervé Wozniak
