Information for UK registered DataCite clients
Please see the DataCite Metadata Schema for current information.
DataCite has created an API for clients who wish to further automate the registration process. Please see the DataCite API documentation for detailed technical information.
A DOI name consists of a prefix and a suffix (e.g. 10.1234/56789). Each data centre is assigned its own prefix.
Data centres create their own suffix structure based on local requirements. We suggest using an opaque, 8-10 digit alphanumeric string. When creating these suffixes, it is useful to bear in mind that DOIs are not case sensitive (i.e. 10.1234/WXYZ and 10.1234/wxyz are the same DOI). DataCite recommends that only the following characters are used within a DOI name: “0-9”, “a-z” and “-._/”
The DataCite system will not accept DOIs longer than 255 characters. You should also keep in mind that DOIs might be used in print, where long DOIs may fall victim to unusual wrapping and line editing, so we recommend keeping DOI names as short as practical but sufficiently complex for your needs.
Can I delete a DOI?
DOIs are intended to be persistent identifiers and, as such, should not be deleted. The preferred approach is to provide a landing page for the DOI that explains why the data set is no longer available. If the DOI was minted in error, DataCite does provide a page you can link to for invalid DOIs.
Invalid and retired DOIs can also be hidden from DataCite search and OAI using a flag within the DataCite database, but users will still be able to resolve the DOI. For further information, please contact us.
