WP4: Theory in the VObs EuroVO-DCA Final Review, 29 April 2009

WP4: Theory in the VObs

Gerard Lemson


Objectives

• Assess the inclusion of theory data and services in the Virtual Observatory

• Theory Expert Group– establish a framework for the inclusion of

theory in the VObs. – organise workshop

• Stimulate national/partner activities.

Reminder: Why special attention to theory ?

• Existing protocols not applicable, observationally biased

• Data models insufficient• Archiving generally ad hoc• No existing standardisation, no “FITS for

simulations”• New use cases

Gerard Lemson


Theory Experts Group (TEG)

• Members: – Santi Cassisi (INAF), Miguel Cervińo (INTA), Gerard

Lemson (MPG, chair), Pedro Osuna (ESAC), Joop Schaye (NOVA), Nic Walton (LU), Hervé Wozniak (CNRS)

• Tasks– SAC workshop– Co-authors whitepaper– Theory Sections in DCA census questionnaire

Euro-VO Theory Workshop• Garching, April 7-9

– followed by WP5 workshop, April 9-11• Program focused on science

– 3+1D simulations– microphysics simulations– theory-theory interoperability– theory-observational interface– computational infrastructure– discussions!

• Proceedings @ Memorie della Società Astronomica Italiana – Supplementi – http://sait.oats.inaf.it/Supplementi.htm– submitted

Some conclusions• 3+1D (“macro”) simulations

– Interest in community high for access (e.g. Millennium)– Interesting services should be deployed:

• visualisation– Data formats need attention (binary VOTable, HDF5)– “Comoving units” ?

• Development in IVOA– SimDB for discovery– SimDAP for access services

• Focus “micro-simulations”– many opportunities for interoperability– community has been pondering standardisation– participants are willing to contribute to VO efforts– workshop “planned”, possibly financed by DCA(AIDA?). – IVOA TIG focus.

Whitepaper

• “Framework for inclusion of Theoretical Astronomy Services in the VObs” – Authors: TEG– Editors: GL, HW, JZ– Contributors: Ugo Becciani, Laurent Bourges,

Igor Chillingarian, Claudio Gheller, Franck LePetit, Patrizia Manzato, Carlos Rodrigo, Enrique Solano.

Recommendations• Participation

– Publication: Scientific results MUST be made available online.– Usage: Online resources SHOULD be used by scientists.

• Standardisation– Definition: Interoperability standards MUST be defined.– Participation: The scientific community MUST be involved in the standardisation process.

• Implementation– Mapping: metadata SHOULD be assigned to published data sets and services according to

IVOA data model standards. – Protocols: services SHOULD implement IVOA standard protocols. – Data formats: Services SHOULD provide results in an IVOA-standard data format.– Applications: VObs aware client tools SHOULD be written. – Registration: Online resources MUST be registered in an IVOA compatible resource registry.

• Resource allocation– Standardisation efforts MUST be supported. – Implementation efforts MUST be supported. – Outreach SHOULD be supported.

Gerard Lemson


Census on theory data centers• 15 institutes• 23 archives (mainly micro-simulations)• 10 services (focusing on theory/observation interface)• non-classical data types: particle properties, hierarchical

trees, isochrones, rate coefficients…• great interest for VO compliance;

already applying VO techniques to a certain degree (VOTable, registered, DAL, SNAP)


Gerard Lemson


IVOA activities• EuroVO-DCA (partners) very active in IVOA.• Participation in theory sessions at interops Beijing (funded!),

Cambridge, Trieste, Baltimore• TIG chair and vice-chair from France/Italy

– Hervé Wozniak/Claudio Gheller– Until May 2008, GL

• Standards development– SimDB+SimDAP (formerly SNAP)

• Meeting in Garching, April 2007, supported by EuroVO-DCA• France/Germany building prototype SimDB• Italy/USA leading SimDAP effort

– S3 proposal from Spain VO• prototypes in SVO and ITVO

– Theory Semantics

Gerard Lemson


Partner activities

• France (Horizon, PDR codes, SimDB)• Germany (Millennium, SimDB, TMAP)• Italy (ITVO@Trieste simulation database,

BaSTI, VisIVO)• Spain (S3 implementations)• See also whitepaper, Appendix B• Some examples (if time permits)
