several questions may be asked by the parties involved, and from the outside:
by the university (for scholarly productivity or promotion and tenure review): what has this researcher published? What do we need to do to accommodate his/her research data output?
by funding agencies: what publications and datasets have been generated by this researcher's work funded by us?
by publishers (of articles, books, etc.): how can we find and identify the researcher and research data "behind" this publication?
by researchers: how can I easily list and cite my publications, datasets, funding sources?
by other researchers: how can I find out which dataset or datasets informed the findings in this publication? What publications resulted from this dataset I discovered?
The combination of Digital Object Identifiers (DOIs) or other persistent identifiers for datasets and publications, and ORCIDs for researchers and research contributors can help establish these linkages easily and unambiguously. (DOIs are discussed in another guide.)
