Curation is an important role that data repositories implement in a variety of ways. As a member of a repository team, what comes to mind when you hear the word “curation”? What does curation include and where does curation occur in the data life cycle? How is the impact of curation measured? These questions are answered in many ways across the broad spectrum of repositories. Many conceive of curation as a process that happens early in the preservation part of the data life cycle; a dataset is submitted to the repository and curation is the process of working with the researcher to enhance the dataset and related metadata to increase suitability for sharing and long-term preservation while increasing the potential for reuse. The result of this curation is a high-quality data package being accepted into the repository. Over the last decade, the emergence of globally unique and persistent identifiers (PIDs) has created new opportunities for engaging with the global research community by connecting existing repository resources to the global research infrastructure. These PIDs did not exist when most data packages currently in repositories were being curated, so we need new retrospective and on-going curation processes that connect these data to a wider range of communities. Examples from Dryad and DataCite will demonstrate approaches and tools for discovering identifiers for papers (DOIs), people (ORCIDs), and organizations (RORs) and re-curating existing metadata to include those identifiers. This will include demonstration of simple metrics for measuring the impact of this re-curation and demonstrating the benefits to repository communities and managers. These re-curation tools are a critical part of reshaping existing metadata and repository processes so they can take advantage of new connections and engage with global research communities.
