<date> Date

Container element for the parts of a single calendar date.

Usage/Remarks

A <date> element may contain date components such as <day>, <month>, and <year> (which are typically given numeric values), as well as non-numeric elements such as <season> (which is a text string).
When used within citations (<element-citation> and <mixed-citation>), this element names the publication date of the cited source. When used as part of <history>, this element holds one of the publication history dates that may be preserved for an article, such as when it was received or when it was accepted.

Best Practice

It is best practice to tag individual date elements (such as <year>) whenever possible. Use <string-date> for the narrative form of a date when necessary, for example, when a date has no month or year specified. However, even inside a <string-date> the named date components, such as <year>, should still be specified.
The Journal Archiving and Interchange Tag Set allows <string-date> both inside <date> and at the same level as <date>. This is the most flexible for allowing the archive to preserve any publisher’s structure. The tighter Tag Sets created from the base Suite may choose to use one or the other in preference.
Related Elements
Within citations (<element-citation> and <mixed-citation>), this element names a date, typically the publication date of the cited source. The elements <year>, <date>, <day>, <month>, and <season> may all be used to describe a date in a citation, both publication dates and other dates. Other dates inside a citation, such as a copyright date, the date on which the author accessed the resource, or a withdrawal date, should be tagged using <date-in-citation> with the @content-type attribute used to name the type of date (copyright, access-date, time-stamp, etc.).
