For additional guidance please refer to ourresearch and publishing ethics tips. For an example on how to cite datasets, please discuss with the references part below. Include persistent identifiers, such as a Digital Object Identifier , in references for datasets and program codes. Persistent identifiers ensure future entry to distinctive published digital objects, corresponding to a chunk of text or datasets. Persistent identifiers are assigned to datasets by digital archives, such as institutional repositories and partners in the Data Preservation Alliance for the Social Sciences (Data-PASS).
