Abstract

The construction of a global network of detectors is the cornerstone to
scientific success for 3rd generation gravitational wave astronomy. If carried
out with a vision to the future, the third generation implementation, in its
infrastructure, technology base and governance can provide the point of
departure for subsequent developments beyond the third generation, a path to
the long and revolutionary future of gravitational wave astrophysics. The goal
of this document is to lay out considerations that influence the optimal choice
of governance and to lay out a possible path that can lead the community to an
optimal governance model.
