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.
