Journal Article Tag Suite
The Journal Article Tag Suite (JATS) is an XML format used to describe scientific literature published online. It is a technical standard developed by the National Information Standards Organization (NISO) and approved by the American National Standards Institute with the code Z39.96-2012.
|First published||31 March 2003|
|Latest version||NISO JATS 1.2|
8 February 2019
The NISO project was a continuation of the work done by NLM/NCBI, and popularized by the NLM's PubMed Central as a de facto standard for archiving and interchange of scientific open-access journals and its contents with XML.
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. JATS allows for descriptions of the full article content or just the article header metadata; and allows other kinds of contents, including research and non-research articles, letters, editorials, and book and product reviews.
Since its introduction, NCBI's NLM Archiving and Interchange DTD suite has become the de facto standard for journal article markup in scholarly publishing. With the introduction of NISO JATS, it has been elevated to a true standard. Even without public data interchange, the advantages of NISO JATS adoption affords publishers in terms of streamlining production workflows and optimizing system interoperability.

There are three tag sets:
- Journal Archiving and Interchange (Green)
- "The most permissive of the Tag Sets," primarily intended for the capture and archiving of extant journal data.
- Journal Publishing (Blue)
- "A moderately prescriptive Tag Set," intended for general use in journal production and publication.
- Formally this model is a subset of the Archiving model. This is the most frequently used JATS variant.
- Article Authoring (Orange)
- "The most prescriptive [tightest and smallest] of the Tag Sets," intended for the relatively lightweight creation of journal articles valid to JATS.
- Formally this model a subset of the Publishing model.
JATS Publishing set defines a document that is a top-level component of a journal such as an article, a book or product review, or a letter to the editor. Each such document is composed of front matter (required) and up to three optional parts. These must appear in the following order:
- Front matter
- The article front matter contains the metadata for the article (also called article header information), for example, the article title, the journal in which it appears, the date and issue of publication for that issue of that journal, a copyright statement, etc. Both article-level and issue-level metadata (in the element
<article-meta>) and journal-level metadata (in the element
<journal-meta>) may be captured.
- Body (of the article)
- The body of the article is the main textual and graphic content of the article. This usually consists of paragraphs and sections, which may themselves contain figures, tables, sidebars (boxed text), etc. The body of the article is optional to accommodate those repositories that just keep article header information and do not tag the textual content.
- Back matter
- If present, the article back matter contains information that is ancillary to the main text, such as a glossary, appendix, or list of cited references.
- Floating material
- A publisher may choose to place all the floating objects in an article and its back matter (such as tables, figures, boxed text sidebars, etc.) into a separate container element outside the narrative flow for convenience of processing.
Following the front, body, back, and floating material, there may be either one or more responses to the article or one or more subordinate articles.
This is the minimal article's structure,
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE article PUBLIC "-//NLM//DTD JATS (Z39.96) Journal Publishing DTD v1.0 20120330//EN" "JATS-journalpublishing1.dtd" > <article dtd-version="1.0" article-type="article" specific-use="migrated" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" > <front>...</front> <body>...</body> <back>...</back> </article>
The root element
article is common for any version of JATS or "JATS family", as NLM DTDs. The rules for
back tags validation, depends on the JATS version, but all versions have similar structure, with good compatibility in a range of years. The evolution of the schema preserves an overall stability.
Less common, "only
back" variations are also used for other finalities than full-content representation. The general article composition (as an DTD-content expression) is
(front, body?, back?, floats-group?, (sub-article* | response*))
There are a variety of tools for create, edit, convert and transform JATS. They range from simple forms to complete conversion automation:
Conversion to JATSEdit
Take as input a scientific document, and, with some human support, produce a JATS output.
- OpenOffice (LibreOffice) and MS Word documents to JATS:
- Typeset: provides automated set of converters for MS-Word to JATS XML.
- OxGarage: can convert documents from various formats into "National Library of Medicine (NLM) DTD 3.0".
- meTypeset: meTypeset "is a fork of the OxGarage stack" "to convert from Microsoft Word .docx format to NLM/JATS-XML".
- eXtyles: automates time-consuming aspects of document editing in Microsoft Word and exports to JATS XML (as well as many other DTDs).
- Markdown to JATS: Pandoc 2.0 can convert a number of input formats to JATS.
- PDF to JATS: this is a very difficult problem to solve. Success depends on how well structured your PDFs are and, for batch conversion, how consistently structured your PDFs are.
Conversion from JATSEdit
Take JATS as input, produce another kind of document as output.
- from JATS to HTML
- from JATS to PDF: some JATS Preview Stylesheets, XSLT + XSL-FO conversion.
- from JATS to EPUB.
- Generic (from JATS DTD): DtdAnalyzer — compare JATS with other DTDs and helps into create a XML representation, XSLT and Schematron generation, and other tools.
- Typeset provides a WYSIWYM editor for scholarly articles. Supports XML exports in NISO JATS and NLM JATS standards. It is mostly used by Journals and Publishers looking to convert author submitted MS-Word files to XML, PDF, HTML and ePuB. 
- JATS Framework for oXygen XML Editor: users of oXygen XML Editor and oXygen XML Author can now install support for current versions of NISO JATS (and as a bonus, NLM BITS). Based on an identifier given in a DOCTYPE declaration, oXygen will detect that you are editing a JATS document and provide stylesheets and utilities.
- FontoXML for JATS: WYSIWYS editor for editing and reviewing JATS content:
- PubRef "Pipeline": Browser-based realtime-preview JATS editor:
- Annotum: a WordPress theme that contains WYSIWYG authoring in JATS (Kipling subset), peer-review and editorial management, and publishing.
- JATS edition for web-based XML editor Xeditor.
- Texture Editor of the Substance Consortium. The first online "born to JATS" editor.
- Libero Editor, developed by eLife describes itself as 'A user-friendly editing interface designed for publishing staff and authors for the production of high-quality JATS XML.'
Tools that render JATS as HTML, usually on fly.
- JATS Preview Stylesheets: the JATS Preview Stylesheets are a series of .xsl, .xpl, .css, and .sch files that will create .html or .pdf versions of valid NISO Z39.96-2012 JATS 1.0 files. It is primarily intended for internal use by publishers and a basis for customization.
- Typeset - Allows to generate HTML from JATS XML within a click. Also, offers capacity to generate custom HTML based on the requirements of the journal. 
- PubReader – "The PubReader view is an alternative web presentation ... Designed particularly for enhancing readability on tablet and other small screen devices, PubReader can also be used on desktops and laptops and from multiple web browsers".
JATS central repositoriesEdit
As NISO JATS began the de facto and de jure standard for open access journals, the scientific community has adopted the JATS repositories as a kind of legal deposit, sometimes deemed more valuable than the traditional digital libraries where only a PDF version is stored. Open knowledge need richer and structured formats as JATS: PDF and JATS must be certified as "same content", and the set "PDF+JATS" forming the unit of legal deposit. List of JATS repositories and its contained:
- PubMed Central: (please check these numbers)
- SciELO: in 2016 ~0.6 million articles
These repositories do overlap and the same article can be held by more than one repository.
Alternatives and semanticEdit
Later, in ~2016, for Semantic Web context, with SchemaOrg initiative, the class ScholarlyArticle was defined, receiving better reception. It is an initial "JATS-like standardization" for RDF contexts of use.
