<version> Version Indicator

A version indicator provides an additional identifier for a non-major release of a standard. The <version> indicator is used to identify updated and publicly released standards that are typically corrections or amendments between major balloted editions of a standard.


For example, in ISO and the family of ISO-related national and regional standards bodies, a <version> element is created when issuing a correction between major balloted editions. A new version does not change the edition number (<edition>), instead the standard acquires a new version indicator (<version>). These version indicators may be a digital counting number (1. 2. 3…), a similar letter convention (A, B, C…), or a textual string naming the version (e.g., “1-amd1.v1-cor3”, for version 1 of the document, as modified by version 1 of Amendment 1 and further modified by version 1 of Technical Corrigendum 3.).
Difference between STS and JATS Version Elements
The <version> element is defined and used differently in NISO STS than it is in JATS:
  • Within standards-specific elements (such as <std-ident>), a <version> element names a version indicator for this standards document.
  • Within JATS-defined citation-related elements (such as <mixed-citation> and <related-object>), a <version> element contains the version statement for the data or software that is cited or described. This usage may be limited to a version digit, but it may also contain ordinals or text as well.
