Document Language

Identifies the official languages used in this standard.


Usage. This element appears once for each official language used in the document. Its value is the two-letter ISO 639 code for the language. For ISO documents, the value will always be one of “en”, “fr”, “ru”, “es”, or “ar” (unless and until the set of official languages changes).

This element is part of the ISOSTS customization of the JATS journal publishing vocabulary; it is not part of the base vocabulary.

Related Elements

The <language> element gives the same information in a different form. In each document there will be just one <language> element, which may have a comma-separated list of language codes as its value (e.g. “en,fr”), while there will be one <content-language> element for each language (e.g. one for “en” and one for “fr”). For monolingual documents, <language> and <content-language> will have the same value.
