There are three types of repository:
Find a subject-specific repository.
Each repository has its own deposit procedure. At Durham, the procedure is:
A member of the Research Support Team will review your deposit and get in touch. After approval, you will get a DOI for your research data. Current Durham RDM policy is to keep all research data in the repository indefinitely.
Cite your own data in your research paper. The bibliographic format, recommended by DataCite is:
Creator (PublicationYear): Title. Version. Publisher. (resourceTypeGeneral). Persistent identifer
Breckon, T ; Tiancheng, G (2018): Pretrained neural network models for Guo 2018 study, TensorFlow format. Durham University. (dataset). DOI: http://doi.org/10.15128/r23j333226h
Dabrowski, K (2018): Computing small pivot-minors. Durham University. (software). DOI: http://doi.org/10.15128/r1t722h881p
N.B. Best practice is to express your DOI as a fully, resolvable hyperlink. That is, express it as http://doi.org/10.15128/r1t722h881p instead of abbreviating it to 10.15128/r1t722h881p. The former resolves, the latter does not.
