VO & Astro-Wise & others A.Belikov OmegaCEN
What will we see? VO: what, why and how? VO Services: examples Astro-Wise data in VO VO data: how to use next steps
Virtual Observatory VO is one standards education implementation
VO & Grid
Why VO? multiband combined surveys (almost) no cast problem
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
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
Description of resources: XML
VOTable the general container for the data XML based multiple data blocks flexibility: tables, images, archives
task: image qualifier machine

Astro-Wise problems: Data RDBMSObjectsXML DBA, AW userAW userVO user interfaces to VO access to AW database fast changes in the data security
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
Registry local publishing registry relational database-like structure python compact: 50 records AW class
VO services catalogs, images ConeSearch, SIA
Registry local dynamic publishing registry
Publishing in Astro-Wise context change privileges visibility scope
Access to VO data VOTable saved on local disk FITS
VO in Astro-Wise: Example
