da|ra assigns persisitent identifiers to digital objects by using the DOI system. The DOI registration is carried out in close cooperation with data providing organisations, such as data archives, research data centres etc., which are responsible for the maintenance and storage of research data and for the maintenance of metadata. The data remain with the data centres; da|ra assigns the DOI names via DataCite, stores the provided metadata and makes the registered contents searchable via a database. The metadata are also freely available via OAI-PMH. da|ra operates a specific metadata schema which is compliant with the Data Documentation Initiative (DDI) Standard. Besides the web based entry mask and a tool for uploading metadata da|ra offers a web service (API) that enables to work automatically with the DOI registration service.
