  Three cornerstones for the 3D data support in the Virtual Observatory are:
(1) data model to describe them, (2) data access services providing access to
fully-reduced datasets, and (3) client applications which can deal with 3D
data. Presently all these components became available in the VO. We demonstrate
an application of the IVOA Characterisation data model to description of IFU
and Fabry-Perot datasets. Two services providing SSA-like access to 3D-spectral
data and Characterisation metadata have been implemented by us: ASPID-SR at SAO
RAS for accessing IFU and Fabry-Perot data from the Russian 6-m telescope, and
the Giraffe Archive at the VO Paris portal for the VLT FLAMES-Giraffe datasets.
We have implemented VO Paris Euro3D Client, handling Euro3D FITS format, that
interacts with CDS Aladin and ESA VOSpec using PLASTIC to display spatial and
spectral cutouts of 3D datasets. Though the prototype we are presenting is yet
rather simple, it demonstrates how 3D spectroscopic data can be fully
integrated into the VO infrastructure.
