What is a data identifier?
A "data identifier" is a permanant identifier that you can use to link to your dataset. There are several types of identifiers that are used by various data repositories and on the web.
The UC Davis Library with the University of California Curation Center (UC3) at the California Digital Library offers EZID, which is a simple service for assigning a unique identifier to digital objects. For instance, if you are publishing a report series, you can use EZID to assign DOIs to each report. (If you use Merritt to store your data, unique IDs are automatically created.)
Contact the Data Services Team for more information on getting an EZID account at UC Davis.
It is important to cite any datasets you use, as well as the published literature that you refer to.
