<year>
Year
Representation,
usually numerical, of a calendar year. (The @calendar attribute can be used to indicate which
calendar, e.g., Gregorian, Thai Buddha, or Japanese.)
Remarks
Usage: In addition to being used for the year of
publication, the <year> is also used to
record “historical” events in the publishing cycle (<pub-history>), for example, the year
the document was released as a preprint or last revised.
The <year> element is used in two contexts: as a part of the metadata concerning the book or book part, and as part of the description of a cited work inside a bibliographic reference (<element-citation> or <mixed-citation>).
Best Practice: When possible, the year should be
expressed as a 4-digit number, for example, “1776”, “1924”,
or “2015”.
