One of the processing dates that may be preserved for a historical book, for example when it was last updated. This element acts (as does the related element <pub-date>) as a wrapper 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.
This element has the same model and attributes in this DTD as it does in the NCBI Book DTD; new attribute values (for example, “translated” and “transcribed”) have been added for the date-type attribute.
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 NCBI Historical DTD 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. Tighter DTDs created from the base Suite may choose to use one or the other in preference.
