  Open GENIE is the successor to the widely used and high successful GENIE
program that is used as the principal front-end neutron data analysis tool at
the ISIS spallation neutron source. In this paper, the background and
motivation for the Open GENIE project are briefly reviewed, as is the progress
to date. Some of the ideas and concepts making Open GENIE unique are
demonstrated. Emphasis is given to how Open GENIE is being used as an integral
component of the new ISIS control system and how it is expected to develop in
the future and how they will impact the field of neutron scattering data
analysis.
