<ref>
Reference Item
One item in a bibliographic list.
Remarks
A <ref> is typically a citation describing a referenced work (see Tagging References). This Tag Set allows notes as well as citations in a bibliographic list, but best practice is to place notes in a <fn-group> or <notes> section and use <ref-list> only for bibliographic citations.
Common Practice: There is usually a number or other label
preceding each citation, for example, [Lapeyre 2015], which a tagger may choose to preserve using the <label> element.
Incomplete References: Some journals identify successive bibliographic references by the same author or involving the same journal by omitting the duplicated portion of the reference and inserting a vertical rule or the word “Ibid” or “Id.” instead of the author’s name or the journal title. Since it is the intention of the Journal Archiving and Interchange Tag Set to preserve the information provided in a bibliographic reference, and since best practice tagging would make each bibliographic reference accessible for Crossref (and similar) queries, such references should be enhanced by tagging the author’s name or the journal title based on the name or title provided in the proceeding reference. At the discretion of the archive the word “Ibid” or “Id.” may also be retained as part of the textual content.

Example 2
Including a mixed-style bibliographic reference (punctuation and spacing preserved):
<article dtd-version="1.2"> ... <back> <ack>...</ack> <ref-list> <ref id="B1"> <mixed-citation publication-type="commun" publication-format="web"> <person-group person-group-type="author"> <name><surname>Harris</surname> <given-names>Pat</given-names></name> </person-group>. <article-title>New Z39.50 resource</article-title> [Internet]. <source>Message to: Karen Patrias</source>. <date-in-citation content-type="time-stamp" iso-8601-date="1998-02-27T13:18">1998 Feb 27, 1:18 pm</date-in-citation> [cited <date-in-citation content-type="access-date" iso-8601-date="1998-02-28">1998 Feb 28</date-in-citation>]. [about 2 screens].</mixed-citation> </ref> <ref id="B2">...</ref> ... </ref-list> </back> </article>
Example 3
This Tag Set allows notes (<note>) in addition to bibliographic citations in a reference list:
...
<ref id="c33">
<label>33.</label>
<note>
<p>While the samples appear homogeneous in terms of local variations in
transition energy and PL intensity, the response to external electric fields
is strongly inhomogeneous, which can most likely be attributed to local
variations in the AlGaN back contact conductivity as well as inhomogeneities
in the passivation process.</p>

......
<ref id="c35">
<label>35.</label>
<note>
<p>The geometric optimization and electronic transport properties are
all calculated by a developed <italic>ab-initio</italic> software package
Atomistix ToolKit, which is based on the spin-polarized density-functional
theory combined with the non-equilibrium Greens functions. ...</p>
