Usage. The value of this element is a comma-separated list (with no whitespace) of the ISO 639 two-letter codes for the official languages used in the document. At present, expected values for monolingual documents are “en”, “fr”, “ru”, “es”, and “ar”. Expected values for bilingual documents are “en,fr”, “en,ru”, and “fr,ru”. The expected value for trilingual documents is “en,fr,ru”.

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 <content-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.
