Drexel University Libraries subscribes to the California Digital Library EZID service to provide persistent identifiers for datasets deposited in IDEA. A "persistent identifier" is an identifier that is available and managed over time; it will not change if the item is moved or renamed. This means that an item can be reliably referenced for future access by humans and software. EZID currently supports persistence for two kinds of identifiers: DataCite Digital Object Identifiers (DOIs) and lower-cost Archival Resource Keys (ARKs). A DOI is an identifier originating from the publishing world and is in widespread use for journal articles. Obtaining a DOI for a dataset allows it to be easily cited in the scholarly literature.
Drexel University Libraries' Guidelines on Providing DOIs for datasets
- Data must be deposited in IDEA
- The creator of the dataset must supply basic metadata required by EZID (this includes Creators, Title, Publisher, and Year of publication)
- Dataset should be one that will be cited in the scholarly record
