In this memo we argue that interoperability between the existing
radio-interferometry packages provides a fast, robust, flexible,
complete, and user-friendly data reduction package for ALMA. We discuss
the meaning of these terms from the point of view of the end-user, the
data reduction specialist, and the package maintainer, and show that an
open software environment provides a cost effective, flexible, and
scientifically more valuable data processing environment than a
monolithic data reduction package. We discuss our first steps toward
interoperation with MIRIAD and GILDAS using python as a command line
interface. For a few years, python has become a natural candidate for
the command line interface both inside and outside ALMA. This is the
first step toward interoperability. We now suggest that ALMA should
think about its data formats (both native and exchange) with the
community to promote interoperability.
