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

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

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

WP4: Theory in the VObs EuroVO-DCA Final Review, 29 April 2009 Gerard Lemson 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! Memorie della Società Astronomica Italiana – Supplementi – –submitted

WP4: Theory in the VObs EuroVO-DCA Final Review, 29 April 2009 Gerard Lemson /20Gerard Lemson, chair WP4 Some conclusions 3+1D (“macro”) simulations –Interest in community high for access (e.g. Millennium)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.

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

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

WP4: Theory in the VObs EuroVO-DCA Final Review, 29 April 2009 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) /20Gerard Lemson, chair WP4

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

WP4: Theory in the VObs EuroVO-DCA Final Review, 29 April 2009 Gerard Lemson Partner activities France (Horizon, PDR codes, SimDB) Germany (Millennium, SimDB, TMAP) Italy simulation database, BaSTI, VisIVO) Spain (S3 implementations) See also whitepaper, Appendix B Some examples (if time permits)
