2. 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.

4. 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

8. WP4: Theory in the VObs EuroVO-DCA Final Review, 29 April 2009 Gerard Lemson 2008-11-19/20Gerard 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.

9. 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.

10. 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.

11. 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) 2008-11-19/20Gerard Lemson, chair WP4

12. 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
