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

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

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

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

7. The Original Small Box

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

10. Data model elements 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

11. Some Nicknames 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

12. 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

13. 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

14. Now includes HAO/MLSO as well

16. 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

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

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

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

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

22. 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.
