Data Citation Use Cases — Data Citation with URL (not persistent) & Data Citation with non-DOI PID.

Use Case Name, Description	Desired Outcome for JATS XML version 1.3	Desired Outcome for Crossref Metadata depository schema 5.3.1	Notes
Use Case 3 Data Citation with URL (not persistent) (e.g., project website, ftp site) The community accepted location for the data does not use persistent identifiers. A URL is provided instead. No DOI registration services are available.	Use <ext-link> to provide a link directly to the data citation. If there is no pub-id, ext-link should be included. <ref id=“bib11”> <element-citation publication-type=“data”> <person-group person-group-type=“author”> <name> <surname> Radoshevich </surname> <given-names>L</given-names> </name>… </person-group> <year iso-8601-date=“2015”> 2015 </year> <data-title> Title of dataset </data-title> <source> ArrayExpress </source> <ext-link ext-link-type=“uri” xlinkhref=“https://www.ebi.ac.uk/arrayexpress/experiments/E-MEXP-1243”>https://www.ebi.ac.uk/arrayexpress/experiments/E-MEXP-1243</ext-link> </element-citation> </ref>	Tags: //citation/unstructured_citation e.g. <citation key=“XXX”> <unstructured_citation>Radoshevich L, …,2015,Title of dataset, ArrayExpress, https://www.ebi.ac.uk/arrayexpress/experiments/E-MEXP-1243,</unstructured_citation > </citation>	Con: Data are not in a trusted preservation repository. Scholix is not updated. The URL is subject to link rot and it is not FAIR. Metadata about the data are difficult to determine.
Use Case 4 Data Citation with non-DOI PID (e.g., RRID, ARKs. Handle, Accession) Additional information in the Software and Data Citation Resources section below. A PID is used for the data but is not a DOI.	<ref id=“bib11”> <element-citation publication-type=“data”> <person-group person-group-type=“author”> <name> <surname> Radoshevich </surname> <given-names> L </given-names> </name>… </person-group> <year iso-8601-date=“2015”>2015</year> <data-title> Title of dataset </data-title> <source> ArrayExpress</source> <pub-id pub-id-type=“accession” xlinkhref=“https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-3649/“ >E-MTAB-3649</pub-id> </element-citation></ref>	Tags: //citation/unstructured_citation e.g.<citation key=“XXX”> <unstructured_citation>Radoshevich L, …,2015,Title of dataset, ArrayExpress,E-MTAB-3649, https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-3649/</unstructured_citation> </citation>	Con: Non-DOI PIDs are not included in Scholix. Non-DOI PIDS are typically not converted to clickable links on journal websites and some journals encourage use of a URL as a preference.
