MUSE is the next generation massive integral field spectrograph for
the VLT, covering 1'x1' at a sampling of 0.2", and will begin
operation in 2014. In return for the major effort in building this
instrument, the MUSE consortium has been awarded 250 nights of VLT
time for the guaranteed time observing.

Due to the nature of MUSE data, each datacube obtained as part of the
GTO programme will be used by most of the consortium nodes which are
spread across Europe. Since the effort required in reducing the data
is significant and to ensure uniformity in analysis, it was desirable
to have a data management system that integrate data reduction,
provenance tracking, quality control and data analysis.

Here we present the MUSE-WISE system which incorporates these
aspect. It is built on the Astro-WISE system originally designed to
handle OmegaCAM imaging data. This has been extended to support 3D
spectroscopic data, including quality control of the data. MUSE-WISE is
currently used to handle simulated MUSE data, laboratory test data and
we will report on our experience of this as well as discuss the
central role of MUSE-WISE in the GTO phase and beyond.
