One of the publication history dates that may be preserved for a book or book component, such as when it was last updated. This element acts (as does the related element <pub-date>) as a container element for date elements, such as <day>, <month>, and <year>, which are usually given numeric values, as well as for <string-date> and <season>, which are just text strings.
For a detailed discussion on the use of <date>, see Dates in Citations.
Conversion Note: 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>, can even be specified.
The Book Tag Set and Collection Tag Sets allow <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.
<!ELEMENT date %date-model; >
(((day?, month?) | season)?, year?, string-date?)
