Researchers are increasingly motivated to make their data available for future use. Repositories are an ideal location to store such data. However, data is now being placed in repositories that were not designed for data, and in some cases, the repositories were explicitly designed for other purposes. Repository staff do not always have the necessary training or tools to handle data, and repository policies do not always reflect the realities of data. This talk will review the challenges unique to storing and managing data within a repository. In particular, it will focus on the factors that repository staff must consider when determining the policies that govern acceptance of new data for their repository and long-term management of data in their repository.
