Ask the Digital Humanities Community - specifically the Archives Community. They have exactly the same issues and have some working models that could be adopted. In part, recognition of the issue requires that new projects build this into any data mobilization strategies (whether that is mobilizing legacy data from museum collections OR mobilizing new data from human or machine observations). This requires building partnerships with the entities (organizations, countries, communities …) to manage expectations and help foster and guide the development of resources needed by these groups to manage data on their end (access to it, storage - if applicable). Talk with Ben Brumfield (fromthepage.com) for more ideas about communities to reach out to about this.
