Cooperation has always been essential in the digital preservation community regarding knowledge exchange and collaboration in research activities. As initiatives increasingly turn to implementation, cooperation also gains practical significance. Initiatives embark on collaboratively building services that are required by various preservation systems.

Activities towards building a file format registry are emerging, as already some preservation initiatives rely on such a future service in their current approaches.
