How small is that box?
Design remains the same as design published in 2002/12, 1.0 release in 2003/12, but....

A sample search experience
• Look for EUV images in a certain time range
![Page 11: The Virtual Solar Observatory: Still a Small BoxThe Virtual Solar Observatory: Still a Small Box J.B. Gurman, G. Dimitoglou, J. Hourclé NASA Goddard Space Flight Center, Solar Physics](https://reader034.vdocuments.mx/reader034/viewer/2022043017/5f4dd35b4a9d74618165f65e/html5/thumbnails/11.jpg)
A sample search experience
• While search is progressing, most browsers will display time range, other search parameters
• Note how nickname “EUV image” translates to a certain wavelength range and a physical observable

A sample search experience
Delivery method determined by data provider(s):
• tarball (requires e-mail address)
• individual links (as here)

Web browser is not the only possible interface
VSO also offers an Application Programming Interface (API)
Can be accessed from software as well
Example: senior undergraduate wrote Java-based client based on existing documentation

Latest features
• Catalog/event list search (metadata as data)
• Joined queries with “normal” data
• Web Services Description Language (WSDL) for other service providers (EGSO, CoSEC)

Internals changes
• Please see poster SH51B-05 (Bogart, Tian et al.) for changes in:
• data model
• performance
• and much more on UI changes

Additional data services
• TRACE
• by image (rather than hourly, compressed file)
• a lot of images
• RHESSI
• GOES SXI
• Yohkoh Legacy
Already added: HANET Meudon OVRO

The “to do” list
• Work with new missions
• STEREO imaging instruments access at STEREO Science Center will use VSO as search engine
• SDO instruments
• Solar-B
• Allow selection by all detector heads/telescopes, filter wheel positions, &c.
• e.g. LASCO C2, clear; Yohkoh SXT, GOES SXI filters
• And more (user comments)....

How generic can we be?
• Could the internals of the VSO be used by VO’s in other disciplines currently planned or under development?
