The purpose is that research objects should be easy to find, access and quote, in order to make research outputs findable and reusable.
A good introduction to the use of DOIs and DataCite can be found in Working with DataCite - Identify, cite, and connect research with confidence.
DeiC leads a consortium of Danish members of DataCite, including universities and research centers. It is expected that the implementation of DOIs will increase - as a natural consequence of the forthcoming Danish strategy for FAIR data.
DeiC finances the costs of consortium participation, including the members' implementation of DOIs.
DeiC invites all research-related institutions with an interest in continuous DOI minting to join the national DataCite consortium.
