Version Statement, Cited

This element is defined and used differently in NISO STS than it is in JATS. Since the NISO STS Tag Sets use both STS amd JATS elements, and standards and journal articles may mix within a single database, in NISO STS, the <version> element has two different contexts with two different meanings.
  • Within standards-specific elements (such as <std-ident> and <std-ref>), a <version> element is an inward-facing element that names the version number for this standards document (e.g., “1-amd1.v1-cor3”).
  • Within JATS-defined citation-related elements (such as <mixed-citation> and <related-object>), a <version> element is an outward-facing element that 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.


Version of this Standards Document: Typically a standards document version number will be a sequence of decimal digits (often just “1”). In more complex ISO-based cases, the version number may be a sequence of hyphen-separated strings giving the base version of the main document and the versions of all applicable supplements, for example, “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.
