Blue Obelisk is (i.e. still active) a remote asynchronous collaboration with no central management or funding. A large part consists of nodes representing software packages. See [[1]]. It works because several of the authors knew/know each other and agreed at the outset to adopt an interoperability mantra "Open Data, Open Standards, Open Source" (ODOSOS). Because everyone agrees the same approach to interoperability the nodes can develop indeoendently! The management is informal - a mailing list and occasional back channels. So there is a collaborative network - see WP article.
