  1. What’s Inside The Small Box? The Virtual Solar Observatory

  2. The Virtual Solar Observatory • Goals • Current Status • The “Small Box” • Data model • Registry & data services schema • Query construction & results engines • API • Outside the box • Data delivery – shopping cart • Adopter’s kit • Compute services • Interface

  3. Goals • Make life easier for the solar needle hunters • Enable large-scale correlative studies – discover new relationships

  4. 3. Location in an EUV image 4. Solar wind velocity 1. Local helioseismology at a coronal hole boundary 2. Subsurface flow map 5. Correlation with stock market (!?)

  5. NSO KPVT SOLIS FTS HAO/MLSO OVRO MSU Yohkoh Current data sources • NASA/GSFC SDAC • SOHO (x. MDI) • SHA • SOHO/MDI • GONG • TON • MOTH • Mt. Wilson

  6. Status • Version Beta 0.7 available • About 1000 uses as of June 2004

  7. The Original Small Box

  8. Data Model • Deliberately simple • Only 17 elements • Push complexity into query translators • Use “nicknames” for common shorthand

  9. Time Observation_Time Duration Time_Step Wavelength Wave_Type Wave_Bands Wave_Minimum Wave_Maximum Wave_Step Data source Observatory Instrument Helioseismology Degree_Minimum Degree_Maximum Degree_Step Physical_Observable Space Observation_Center_West Observation_Center_North Bounding_Radius Data model elements

  10. Images White-light Coronagraph H-alpha Ca K He 10830 Na D Soft X-ray Hard X-ray EUV UV 10.7 cm Continuum Line-Depth Magnetograms Full-disk LOS Vector Dopplergrams Full-disk Na D Ni 6768 K xxxx Synoptic maps Magnetic Doppler Intensity Some Nicknames

  11. Registry & Data Services Schema • In XML • VSO Registry describes data providers and their holdings at high level • Data services schema fully detail contents of the local archive

  12. Query Construction & Results Engines • In Perl • Driven from web interface: • Creates new web table with further selection capability • Or driven via API: • Returns URL of data locations

  13. Now includes HAO/MLSO as well

  14. The API • Three paths currently available: • Perl with SOAP:Lite • Java using Axis • C or C++ using gSOAP • Plus a WSDL document describing the API

  15. Outside the box • Shopping Cart • Adopter’s kit • Compute services • Advanced interface

  16. Data Delivery • Currently done with existing data provider systems • Shopping Cart will unify data delivery • See poster by Suárez-Solá

  17. Adopter’s Kit • Designed for easy addition of archives • Lightweight • Uses Perl • Requires data service schema

  18. Compute services • Will be future development path • Integrate with CoSEC, EGSO, etc. • Needed to fully realize the potential of VxOs

  19. Interface • Users want to query data via graphics • Calendars, clocks and movies for time • Drawing tools on images for space • Drawing tools on line plots for wavelength and time • No typing! • Pull-down menus • Check boxes, radio buttons, etc.

  20. Next generation VSO interface mock-up? BB Hα Select Date
