2 Motivation Education Education Science Science We want a simple tool We want a simple tool Gives quick results Gives quick results Easy to extend – add more services Easy to extend – add more services The motto: The motto: If you can teach a child to use the VO, you can teach an astronomer.If you can teach a child to use the VO, you can teach an astronomer.

3 The Environment Why Java? Why Java? Rafael said it was Macho…Rafael said it was Macho… Can put it all in a simple WAR file (~20Mb).Can put it all in a simple WAR file (~20Mb). Can use existing VO LibrariesCan use existing VO Libraries To use it, you just need a browser (any browser!)To use it, you just need a browser (any browser!) Easy to deploy at different servers, OSes, sitesEasy to deploy at different servers, OSes, sites

5 DataScope for the People (not a very good name)

6 We present the Pocket-VO It is for public, extensible for astronomers It is for public, extensible for astronomers

7 Why do we call it Pocket VO? It is: It is: SmallSmall Simple to useSimple to use Machine/OS- independentMachine/OS- independent Leaves the hard work to the server (not to your machine)Leaves the hard work to the server (not to your machine) You can literally put it in your pocket (or in your backpack, or…)You can literally put it in your pocket (or in your backpack, or…)
