<version> Version Statement

A full version statement, which may be only a number, for data or software that is cited or described.


The <version> element is only used as part of a description of a cited work inside a bibliographic reference (<element-citation> or <mixed-citation> and similar elements). To describe the version of a book or book-part, use <content-version>.
The content of this element may be a simple version number (such as “<version>16</version>” or “<version>XII</version>”). More complex version statements may contain a textual statement (“Fifth PC version, patches 2-3”), dates that the dataset covers, the version number as an ordinal (“3rd” or “3rd version”), or superscripted ordinals (“4<sup>th</sup>” or “10<sup>th</sup> version”). Whether or not the content is more than a simple number, the @designator attribute of this element can be used to hold the simple numerical or alphabetic version number, if there is such a number (<version designator="16.2">16th version, second release</version>).
