1. VO & Astro-Wise & others A.Belikov OmegaCEN A.N.Belikov@astro.rug.nl

2. What will we see? VO: what, why and how? VO Services: examples Astro-Wise data in VO VO data: how to use next steps

3. Virtual Observatory VO is one standards education implementation

4. VO & Grid

5. Why VO? multiband combined surveys (almost) no cast problem

6. Simplicity of VO parametrized request to the data XML for data exchange XML for data description wrapped data (images) simple range request required parameters for request required parameters for result

7. www.ivoa.net

8. Publishing in VO put data in a place available for an external user provide a standard VO service (ConeSearch- STA, SIA, SSA) register data data storage (RDBMS) http server registry interface ODBC VO standards end-user

9. Description of resources: XML

10. VOTable the general container for the data XML based multiple data blocks flexibility: tables, images, archives

11. task: image qualifier machine

12. Hierarchy of resources WENSS OmegaCEN http://vo.astro-wise.org/ConeSearch?FORM=VOTABLE&PROJECT=WENSS http://vo.astro-wise.org/SIAP?FORM=VOTABLE&PROJECT=WENSS dbview.astro-wise.org

13. Astro-Wise problems: Data RDBMSObjectsXML DBA, AW userAW userVO user interfaces to VO access to AW database fast changes in the data security

14. Astro-Wise problems: Access uniform identifier access by project, instrument as less changes in AW concept as possible VO layer on top of AW more functionality

15. Registry local publishing registry relational database-like structure python compact: 50 records AW class

16. VO services catalogs, images ConeSearch, SIA http://vo.astro-wise.org/ConeSearch?FORM=VOTable&PROJECT=ESO-LV http://vo.astro-wise.org/ConeSearch?FORM=VOTable&INSTRUMENT=WFI@2.2m http://vo.astro-wise.org/SIAP?FORM=VOTable&PROJECT=ESO-LV

17. Registry local dynamic publishing registry

18. Publishing in Astro-Wise context change privileges visibility scope

19. Access to VO data VOTable saved on local disk FITS

20. VO in Astro-Wise: Example
