<pub-date>

Publication Date

Container element for the parts of a single date associated with an article’s publication (for example, date preprint was released, date article was published in print).

Remarks

As part of the article metadata, the <pub-date> is allowed to repeat; each repetition can take a different @publication-format attribute to distinguish which form of publication, for example, print publication, electronic publication, etc. and a @date-type attribute to distinguish between preprint, publication, revision received, etc.
While most publication dates will either be a season and a year (for example, Spring 1999) or a year with a possible day and month (for example, January 1, 1999), sometimes the publication date will identify both the season and date. A publication date of “Spring 1999; January 29, 1999” should be tagged:
<pub-date publication-format="print" date-type="pub"
      iso-8601-date="1999-01-29">
    <season>Spring</season>
    <day>29</day>
    <month>01</month>
    <year>1999</year>
  </pub-date>
