The identifier of a publication, such as a related journal article, that is listed within a <element-citation> or <mixed-citation> inside an article’s <ref-list>
The @pub-id-type attribute is used either to identify the type of identifier, or to name the authority, organization, or system that defined this identifier, for example identifying a DOI, PubMed Central identifier, PII, the publisher’s identifier, etc. (See @pub-id-type for values.)
The Archiving Tag Set includes two elements which may be used to record a DOI as an identifier: <object-id> and <pub-id>. The <object-id> is used to identify parts of an article, e.g., a particular section, a figure, a table, or even a specific citation (as an entity) in the article’s bibliographic reference list. The <pub-id> element is used inside a citation to identify a cited publication. Consequently, a bibliographic reference (<element-citation> or <mixed-citation> could contain both the <object-id> element (with the DOI for that citation) and the <pub-id> element (with the DOI for the journal being referenced in the citation) as shown by the example below:
<article> <front> ... <article-meta> <article-id pub-id-type="doi">MyPub.20070215.03154</article-id> ...</article-meta> </front> <body>...</body> <back> <ref-list> ... <ref id="B6"><label>6</label> <citation> <object-id pub-id-type="doi">MyPub.20070215.03154.s433</object-id> ...</citation> </ref> <ref id="B7"><label>7</label> <citation> <object-id pub-id-type="doi">MyPub.20070215.03154.s434</object-id> <person-group person-group-type="author"> <name> <surname>Brook</surname> <given-names>I.</given-names> </name> </person-group> <article-title>Infant Botulism</article-title> <source>J Perinatol.</source> <year>2007</year> <volume>27</volume> <issue>3</issue> <fpage>175</fpage> <lpage>180</lpage> <pub-id pub-id-type="pmid">17314986</pub-id> <pub-id pub-id-type="doi">10.1038/sj.jp.7211651</pub-id> </citation> </ref> <ref id="B8"><label>8</label> <citation> <object-id pub-id-type="doi">MyPub.20070215.03154.s435</object-id> ...</citation> </ref> <ref id="B9"><label>9</label> <citation> <object-id pub-id-type="doi">MyPub.20070215.03154.s436</object-id> ...</citation> </ref> </ref-list> </back> </article>
