A dataset citation includes many of the same components of a traditional citation.
Many style manuals have not developed specific instructions for citing data. If the style guide you are using does not address data citations, you may use the basic citation elements, regardless of the type of work.
author(s) (Who created the data? an organization, individual, group of individuals) ,
title (name of the study or title of the dataset),
year of publication,
publisher (or location of where the data was found)
access information (URL/doi where data was found)
Several discipline specific resources are listed in the "Citation Guides" tab.
If you use data from the ESRI Data and Maps collections on GISPUBLIC, this blog post provides information on how to properly cite those resources. The post refers to the "Redistribution Rights Matrix" but the link is for an older version of the collection. Current versions can be accessed for all of the annual collections in the GISPUBLIC\GISdata\ESRIdata folder by viewing the "help.htm" file located within each of the subfolders.
