A Virtual Tour of theVirtual Observatory

(a presentation taken from the ESO-VO day)
The VO Concept
• VO: all astronomical data on your computer
• What the VO is NOT:
‣ A centralized database of all astronomical data‣ A “monolith” software system‣ A peer-to-peer system
• The VO framework
‣ Agreed standards‣ Inter-operable data collections‣ Inter-operable tools and applications
Behind the scene• Global standards➡ Transparent inter-operability for the end
users
• Working data services
• VO aware client tools and portals➡ Data Access
• VO aware data mining services
On stage
➡ Registry what, where, who, when, howVO tools, applications and services(VO aware people making their data available)
a word about the registry
a quick tour of some VO tools and services
• Topcat
v
Aladin
• Spectra Tools
‣ Multi-archive spectra/SED
e.g. VOSpec
• VisIVO - server side visualisation
VO services
X-match facilities
An integrated Data Mining framework for massive Datasets:
Target: Users, Data Miners and Developers.
A user friendly to use not-user-friendly algorithms.
Expansible: develop your own plugins, deploy it on your computing environment.
Thanks to the cool VO Tools you now have access to big datasets.
What to do with them?!
Party with your data!!(K.Borne)
