In this paper we present the envisaged setup and changes to the current Mikulski Archive
for Space Telescopes (MAST) configuration at the beginning of operations for the James
Webb Space Telescope mission. The placing of the observatory at L2 and long periods
of autonomous operations mean that observations can be split over several time periods
or 'visits'. Data are processed through standard science data reduction pipelines
after arriving at the Space Telescope Science Institute (STScI). We describe how data
from visits and pipeline processing lead to the data products that are to be stored
in the archives. Most observations will require a number of exposures; we discuss
the data associations that will formulate the highest level of pipeline products that
will be available in the MAST archive for JWST. The JWST observatory has numerous
spectroscopic modes, including integral field units and multiple object spectra which
will distinguish it from the Hubble Space Telescope archive. We describe the expected
data products and services. Finally, we discuss the links to data analysis software
and archive products available for user reprocessing.
