The Digital Object Identifier (DOI®) System is used to uniquely identify an object such as an electronic document or dataset. Metadata about the object is stored in association with the DOI name. The metadata may include a location, where the object can be found, such as a URL. The DOI for a document is permanent, whereas its location and other metadata may change. Referring to an online document by its DOI provides more stable linking than simply referring to it by its URL. DOIs are widely used by the citations in IEEE and many journals.
A DOI can be resolved simply by searching for it at http://www.doi.org. For example, searching on the DOI 10.4231/D3N00ZS79 goes directly to the specific experiment page on NEEShub.
As a part of NEEScomm's effort to facilitate re-use of and improved access to research data, NEEShub has the capability to provide a DOI for the dataset at the experiment level in the Project Warehouse. Users can request a DOI for an experiment during the curation process. Requesting the DOI happens at the same time curation is requested.
To request a DOI, use the Curation Dashboard on the right in the Edit Experiment page. Select the checkbox for "Create a DOI" and click the "Start Curation" button. A dialog window will popup to fill the metadata for DOI such as authors and tags. Other metadata, such as title and description, are pulled from the experiment. After filling the DOI metadata, click the "Save DOI" button to save the metadata and send a curation request to the Data Curator. The DOI will show as "Pending" next to the experiment title; it will be issued when the curation of the experiment is complete.
Besides the regular approach indicated above, DOI requests can also be sent directly to the Data Curator at firstname.lastname@example.org.
