Slide 22

IVOA SPM 2006, Moscow22 VO Data Access Service (VO-DAS) Based on comparative mature Grid middle-wares, for example Globus Toolkit and OGSA-DAI, the VO-DAS system will provide VO-compliant, uniform access interfaces for different kinds of astronomical resources existing as VO services, databases, file systems and even data mining algorithms and other applications. From Aug 14th, VO-DAS project has been turned from design stage to coding stage. A preview version will be available by the end of the year. The first public release will be in the IVOA 2007 Spring Interoperability meeting.
