hasdaiis a network of Invenio repositories which preserves research data resources for partners in a spectrum of different scientific domains. Data Futures operates hasdai on behalf of its partners and CERN. In addition to preservation hasdai supports research into institutional guarantee—to reduce operating costs of high-availability data services—and also into discovery mechanisms for and sharing of stand-off metadata such as annotation.

This website provides access to both Invenio repositories and to the research projects to which Data Futures contributes—move between the two types of content using the buttons at the top. The research projects are often active and do not all provide detailed public access—though there is a summary in all cases; repositories are public snapshots—research 'at rest'—and support browsing and in some cases machine interfaces.
