Technical specifications for DataCite DOI identifiers
Unsure what to consider when obtaining a DOI? Learn more about the minimum metadata requirements of DataCite DOIs and the supported interfaces.
What do DOIs require?
- The metadata of a research dataset must be located on a single landing page with a URL.
- The compulsory metadata of datasets must be stored in the DataCite service.
- Landing page addresses must be as persistent as possible.
- If the data are removed, the DOI must continue to refer to a website that describes what has happened to the data (tombstone page).
- In practice, managing DOI identifiers requires an application programming interface (API) from data repositories.
What are the minimum requirements for metadata?
Datasets must have at least these metadata:
- Identifier
- Author
- Title
- Publisher
- Year of publication
- Data type
How are DOI identifiers managed?
Data repositories that wish to enable DOI identifiers must contact Data Support at datasupport@helsinki.fi.
Data Support will create repository-specific DOI prefixes for each repository. In addition, Data Support provides credentials for a management tool, enabling the creation of DOI identifiers through application programming interfaces (API).
