Now formally approved by ANSI, NISO has published the updated version of JATS: Journal Article Tag Suite Version 1.1, ANSI/NISO Z39.96-2015. This newly official edition is a revision of ANSI/NISO Z39.96-2012, also known as JATS 1.0, first published in July 2012. JATS 1.1 includes changes based on comments from users made on JATS 1.0 through February 2015, which have been addressed by the NISO JATS Standing Committee. All changes are also backward compatible with JATS 1.0, which means that any document that was valid according to JATS 1.0 will be valid according to JATS 1.1. The Journal Article Tag Suite provides a common XML format in which publishers and archives can exchange journal content. The JATS provides a set of XML elements and attributes for describing the textual and graphical content of journal articles as well as some non-article material such as letters, editorials, and book and product reviews. Documents are available via the JATS web pages.
