It aims to allow seamless access to distributed
astronomical resources, and to provide the necessary
tools to analyse data and produce scientifically
relevant results. In this context, access to multi-wavelength
data obtained with
ground-based telescopes and space-borne observatories
and their full interoperability is a key element to the full
exploitation of the possibilities offered by the VO.
The EURO-VO project has now entered its operational phase. It provides
support to the scientific community for utilizing the VO
infrastrucutre through dissemination and tool prototyping
as well as by directly supporting projects making use of the
VO environment. It also provides services for data access and
computing data products.
