Tagging Ordinal Numbers
Cited Edition Statements: Edition statements (<edition>) in JATS journal articles are allowed only within citations (<mixed-citation> or <element-citation>), not in the metadata for the article (<article-meta>). Edition statements inside citations are frequently given as ordinal numbers (first, second, third) and abbreviated with an “st”, “th”, or “rd” suffix. These ordinals may either directly follow the number (4th) or be placed in a superscript following the number (4<sup>th</sup>). JATS allows some flexibility in placing these ordinals, and each publisher or archive will need to decide whether or not these ordinal suffixes are part of the element’s content.
For example, consider the citation that names the edition as “3rd”:
- To regularize content for searching, eliminate these extra characters and tag the edition as <edition>3<edition>.
- To record exactly each detail for a printed volume, retain
these extra characters:
- inside the edition statement: <edition>3<sup>rd</sup><edition>
- outside the edition statement inside the text of a mixed citation: <edition>3<edition><sup>rd</sup>
- inside the edition statement, using the @designator attribute to preserve just the number:
... <edition designator="3">3<sup>rd</sup></edition> ...
Volume Numbers: In the Authoring Tag Set, the volume number element (<volume>) can be used inside citations (<mixed-citation> or <element-citation>).
The ordinals used with a volume number can be:
- inside the volume number: <volume>1<sup>st</sup><volume>
- outside the volume number inside the text of a mixed citation: <volume>1<volume><sup>st</sup>
The related <volume-id> element is used to record an identifier, such as a DOI, that describes an entire volume of a journal or series.
