Policy plays an important role in articulating the scope of a repository. As UMass Amherst grows its data repository, it is evident that policies around what is acceptable to deposit, the roles librarians and libraries take, and workflows around data deposit are important stepping stones for communication and expectation management. In this talk, Thea Atwood, Data Services Librarian, and Ann Kardos, Metadata Librarian, will discuss the establishment of the data repository, the individuals and groups that support the data repository, and the group’s approach to writing policy that is responsive and flexible.
