Presentation Transcript

  1. VO Applicationinteroperability study« VOApp.compareTo(PLASTIC) » Pierre Fernique CDS

  2. Cross correlate data by using simultaneously collaborative VO applications Requirements : Data transfer mechanisms Cross selection objects/regions …and a large screen ! The goal

  3. Example: VOPlot/Aladin cross selections VOPlot reddest objects selections correspond to the Aladin dense regions

  4. Some solutions Without cross-selection  usual solution • Via files : Save and load => data standards (FITS and VOTable) • Via a Copy and paste function => data standards (OS dependent) With cross-selection  dedicated solution • VOApp java interface (new ExtApp version) • PLASTIC hub

  5. PLASTIC A local daemon (HUB) Events by sockets + predefined messages (via RMI or XML-RPC) VOApp Unique java virtual machine Events by method calls (via a Java interface) The technical choices API One java machine VOPlot PlasticHub VOApp VOApp API API Topcat

  6. VOApp / Plastic implementations

  7. VOApp.compareTo(PLASTIC) Capabilities Implementation

  8. VOApp P.Fernique, F. Ochsenbein [CDS] S. Kale [VO-India] T. Donalson [STScI] http://aladin.u-strasbg.fr/java/FAQ.html #VOApp PLASTIC J. Taylor, M. Taylor, N. Wistansley [Astrogrid] T.Boch [CDS] M. Comparato [INAF]  http://plastic.sourceforge.net Who ?

  9. PLASTIC  multi-language  generic collaborations  Certainly a good candidate for a new VO standard. VOApp  only in Java world  dedicated collaborations  high performances Which one ?
