The ANU Data Commons is a repository for research data sets created and owned by ANU researchers. It allows researchers to deposit, update, and publish their data sets to Research Data Australia while retaining ownership. The Data Commons is built on projects to identify existing data sets and capture new data as it is generated. It uses Fedora Commons technology with access controls and an interface for uploading data. Deposited data receives backup storage and there are no limits on size or type. The Data Commons is in open beta and aims to work with researchers to populate the repository and Research Data Australia with at least 50 data sets.
