A persistent identifier (PID) is a unique and permanent digital reference that makes it possible to find and reuse digital material. PIDs are used to reference digital objects such as documents, web pages, and files.
Every dataset that is deposited and made accessible at SND has a specific type of persistent identifier (PID) called a Digital Object Identifier (DOI). This helps ensure correct citation of the primary researchers, as well as showing which version of the data has been used. In order to publish material based on these datasets in a journal, it is often a condition that the research data is accessible and equipped with a PID.
SND’s membership of DataCite
As a member of DataCite SND is able to provide a DOI prefix to Swedish authorities and institutions that work with preserving and making research data accessible. This is regulated in DataCite’s Business Models Principles (Chapter 4). As the process of assigning a DOI requires a certain amount of metadata for every object, it may, depending on the data type, be more appropriate to use another type of PID. Other common types of PID are available through ePIC (handle), KB (urn:nbn) (in Swedish only), and CDL (ARK).

These institutions have been issued a DOI prefix via SND.
DataCite: Statistics, collaboration and development projects
The DataCite website provides access to, among other things, statistics and API documentation. A collaboration with Thomson Reuters means that DataCite is now also included in the Data Citation Index. A collaboration between ORCID and DataCite has been built within the framework of the ODIN Project. Project Thor follows on from the ODIN Project. DataCite’s service also includes re3data.org, a global registry of research data repositories and their equivalents.
