In this model, there is a process to migrate objects from the research to the
collaboration, and the collaboration to the publication, domains. In some cases, the
movement will be in name only, due to storage or other limitations. That is, an object
may stay in a research or collaboration repository but be exposed in the publication
domain. Obviously, this has security implications for the underlying repository
infrastructure. As Figure 1 shows, this migration process involves a mixture of
human and computer actions. In practice, humans will need to make selection
decisions and then use automated assistance to modify and augment the objects as
they cross the curation boundary. The University of Hull is currently exploring the role
of workflows in facilitating this sort of processing in their Repository Metadata
Management (RepoMMan) project (Hull 2007). The process of crossing the
collaboration curation boundary will probably be more lightweight than the process of
crossing the publication curation boundary.
