TU Delft Library is a founding member of DataCite and a regional office for the Netherlands. TU Delft Library has established DataCite Netherlands to serve as a central research dataset registration service that will enable Dutch research organizations to register research datasets and assign digital object identifiers (DOIs) to them. Our aim is to support researchers by improving access to research data and to increase acceptance of the research data as legitimate, citable contributions to scientific record through trustworthy registration and identification of datasets. Current focus of DataCite Netherlands is promoting the use of digital object identifiers for datasets.
What is a DOI?
A digital object identifier (DOI) is a character string ("digital identifier") used to uniquely identify an object such as an electronic document. Metadata about the object are stored in association with the DOI name and these metadata may include a location, such as a URL, where the object can be found. The DOI for a document is permanent, whereas its location and other metadata may change. Referring to an online document by its DOI provides more stable linking than simply referring to it by its URL, because if its URL changes, the publisher needs only to update the metadata for the DOI to link to the new URL.
Basic DOI syntax
The DOI is made up of two components, a prefix and a suffix, separated by a forward slash.
Example of a DOI: 10.4121/uuid:c1ac7344-1419-4398-ba13-c757551c303f
All DOI prefixes begin with "10" to distinguish the DOI from other implementations of the Handle System followed by a number of four or more digits. The prefix is assigned by the registration agency. The suffix is assigned by the data centre, i.e. the institution that is responsible for the content.
