Modules in the Journal Archiving Tag Set and JATS DTD Suite

The Suite was created to allow a multiplicity of Tag Sets, based on the needs of the intended use, for example, an authoring Tag Set versus an archiving tag set for a repository. The Journal Archiving Tag Set (JATS-archivearticle1.dtd) and its specific customization modules (%archivecustom-classes.ent;, %archivecustom-mixes.ent;, %archivecustom-models.ent;, and %archivecustom-modules.ent;) define an archival and interchange focused Tag Set. The following modules are critical for the customization process that creates that Tag Set:
Journal Archiving and Interchange DTD
(File name JATS-archivearticle1.dtd) The top-level Journal Archiving Tag Set Module that declares the document element (<article>) and the other top-level elements that define a journal article (front matter, back matter, and sub-articles or responses). All elements but these few are declared in the modules of the Suite. The DTD invokes all the other modules it uses, by reference, as external parameter entities: first the Archiving Tag-Set-specific Module of Modules is called to name all Archive-specific customized modules, then the Suite Module of Modules is called to name all the potential modules from the Suite, then customized and default modules are called (for parameter entities naming element classes, mixes, and models), then the Common Module for shared elements and attribute lists is called, and finally all the other modules are called as needed.
Archiving Tag-Set-specific Module to Name Modules
(parameter entity %archivecustom-modules.ent;) Defines all the external modules that are specific to the Archiving Tag Set (except itself, which must be both named and called inside the DTD). A Tag Set selects from these modules by referencing the module names through external parameter entities. The entities are declared in the Archiving Tag-Set-specific Module of Modules (%archivecustom-modules.ent;), but referenced (or not) in the DTD proper. To include a set of elements (such as all the lists or all the MathML elements), a DTD references the external parameter entity of the module that contains these declarations.
Implementor’s Note: The Archiving Tag-Set-specific Module of Modules and the Suite Module to Name the Modules (along with the MathML 3 modules, if used) need to be the among the first three external modules called by the Archiving DTD. Customization modules for classes, mixes, and models will typically be called following the Archiving Tag-Set-specific modules and the Module of Modules.
Archiving Tag-Set-specific Class Customizations Module
(parameter entity %archivecustom-classes.ent;) Sets up parameter entities that will be used to override default classes prescribed by the %default-classes.ent; module.
Implementor’s Note: This module must be called after the Archiving Tag-Set-specific Module of Modules (%archivecustom-modules.ent;) and the Suite Module to Name the Modules (%modules.ent;) but before any other module, including specifically the %default-classes.ent; module (which this module overrides) and the %archivecustom-mixes.ent; and %archivecustom-models.ent; modules (which build on this module).
Archiving Tag-Set-specific Mix Customizations Module
(parameter entity %archivecustom-mixes.ent;) Sets up parameter entities that will be used to override default mixes (groupings made of “classes”) prescribed by the %default-mixes.ent; module.
Implementor’s Note: This module must be called after the Archiving Customize Classes Module (%archivecustom-classes.ent;) and the Default Classes Module (%default-classes.ent;) but before any other module, including specifically the %default-mixes.ent; module (which this module overrides) and the %archivecustom-models.ent; module (which builds on this module).
Archiving Tag-Set-specific Models/Attributes Customizations Module
(parameter entity %archivecustom-models.ent;) Sets up parameter entities that will be used to override default content model parameter entities set elsewhere in the Suite. Also defines customizable attribute Declared Values and attribute lists for the Tag Set being defined.
Implementor’s Note: This module must be called after the Archiving Tag Set Customize Mixes Module (%archivecustom-mixes.ent;) and Default Mixes Module (%default-mixes.ent;) but before any “base” module of the interchange Suite.
The NISO JATS common modules, which are overridden by the customizations, include the following:
Suite Module to Name the Modules
(parameter entity %modules.ent;) Defines all the external modules that are part of the modular NISO JATS DTD Suite (except the module itself, which must be both named and called inside a DTD). A Tag Set selects from the Suite modules by referencing the module names through external parameter entities. The entities are declared in the Module to Name the Modules (%modules.ent;), but referenced (or not) in the DTD proper. To include a set of elements (such as all the article metadata or all the display elements) a DTD references the external parameter entity of the module that contains these declarations.
Implementor’s Note: The Archiving Tag-Set-specific Module of Modules and the Suite Module to Name the Modules (along with the MathML 3 modules, if used) need to be the among the first three external modules called by the Archiving DTD. Customization modules for classes, mixes, and models will typically be called next, following these two.
ALI Namespace Module
(parameter entity %JATS-ali-namespace.ent;) Namespace setup for the NISO Access License and Indicators elements (prefix “ali:”). The elements are defined in the JATS Common module (described below).
Common (Shared) Attributes Module
(parameter entity %JATS-common-atts.ent;) Defines attributes intended to be used on ALL elements defined in the NISO JATS, including table elements for both the XHTML-inspired and OASIS-inspired table models, with the exception of <mml:math> whose namespaces JATS does not control.
Must be called after all module-of-modules modules and any namespacing modules, but before all customization (over-ride) modules.
Suite Default Element Classes Module
(parameter entity %default-classes.ent;) Sets up the parameter entities that name the element members of each class that will be used to establish the content models.
Implementor’s Note: This module must be called before the Archiving Customize Mixes Module (%archivecustom-mixes.ent;) and the Default Element Mixes Module (%default-mixes.ent;), as well as the Archiving Customize Models Module, %archivecustom-models.ent; (which builds on those modules).
Suite Default Element Mixes Module
(parameter entity %default-mixes.ent;) Sets up the parameter entities that name mixes (groupings made of “classes”) that will be used to establish the content models.
Implementor’s Note: This module must be called before the Archiving Customize Models Module (%archivecustom-models.ent;) or any “base” module of the interchange Suite.
Common (Shared) Elements Module
(parameter entity %common.ent;) Declarations for elements, attributes, entities, and notations that are shared by more than one class module.
Implementor’s Note: This module must be called before any of the modules comprising the interchange Suite.
The modules that define the elements and attributes that make up the Suite are defined by the following modules. These too may be overridden by the customization modules of the Archiving DTD.
Article Metadata Elements Module
(parameter entity %articlemeta.ent;) Declares the metadata elements (issue elements and article header elements) used to describe a journal article.
Design Note: Metadata elements that describe the journal are in the Journal Metadata Module, %journalmeta.ent;.
Back Matter Elements Module
(parameter entity %backmatter.ent;) Declares elements that are not part of the main textual flow of a work, but are considered to be ancillary material such as appendices, glossaries, and bibliographic reference lists.

Format Class Elements Module
(parameter entity %format.ent;) Declares elements concerned with rendition of output, for example, printing on a page or display on a screen. This module includes the elements in the Appearance Class, the Break Class, and the Emphasis Class.
Funding Elements Module
(parameter entity %funding.ent;) Declares elements that model open access, grant, sponsorship, or other funding information, for example, the grant number (<award-id>) and the grant holder (<principal-award-recipient>).
Journal Metadata Elements Module
(parameter entity %journalmeta.ent;) Declares the elements used to describe the journal in which a journal article is published.
Design Note: The issue and article metadata is defined in the Article Metadata module, %articlemeta.ent;.

The modules that define the NISO JATS XHTML-inspired table model are:
NISO JATS XHTML-inspired Table Setup Module
(parameter entity %XHTMLtablesetup.ent;) Sets all parameter entities needed by the NISO JATS XHTML-inspired Table Module, and then invokes the module containing that model.
To include the NISO JATS XHTML-inspired table model in a tag set, a DTD must reference this module. This module sets up all parameter entities needed to use the XHTML-inspired Table Module and references (invokes) the NISO JATS XHTML-inspired Table Module. (See next item.)
NISO JATS XHTML-inspired Table Module
(parameter entity %xhtml-table-1.mod;) The public XML DTD version of the XHTML-inspired Table Module. This module is invoked from the module %XHTMLtablesetup.ent;. (See previous item.) This is the default table model for this Tag Set.
NISO JATS XHTML-inspired Table Style Module

The modules that may be used to define a version of the Archiving DTD that uses the OASIS XML Exchange (CALS) table model include the following. Several of these modules (such as the DTD itself and the class customization module) are replacements for the default Archiving DTD and customization modules.
Journal Archiving and Interchange DTD with OASIS Tables (JATS-archive-oasis-article1.dtd)
Complete Archiving (Green) DTD for the creation of new journal articles. This extension of the Journal Archiving and Interchange DTD replaces the Archiving DTD module and invokes both the XHTML table and the CALS OASIS XML Exchange Table models.
Journal Archiving and Interchange DTD with OASIS Tables DTD-Specific Modules (JATS-archive-oasis-custom-modules1.ent)
The DTD-specific modules for the new Journal Archiving and Interchange DTD that includes OASIS Tables.
Journal Archiving and Interchange DTD with OASIS Tables Customize Classes Module (JATS-archive-oasis-custom-classes1.ent)
The class overrides for this new DTD. These repeat all the class overrides of the regular Archiving DTD, with the table and alternative classes modified to use the OASIS XML Exchange (CALS) table elements. There is no equivalent mix override module because this DTD uses the ordinary Archiving mix overrides.
JATS OASIS Table Namespace Module (JATS-oasis-namespace1.ent)
This modules establishes the prefix for the OASIS Exchange (CALS) table model, by default “oasis” (“<oasis:table>”).
JATS Namespaced OASIS XML Table Setup Module (JATS-oasis-tablesetup1.ent)
(parameter entity %oasis-tablesetup.ent;) Implementor’s Note: Not used in the current Archiving Tag Set. Sets all parameter entities needed by the OASIS XML Exchange (CALS) table model, and then invokes the module containing that model.
To include the OASIS XML Exchange (CALS) table model, a DTD must reference this module. This module sets up all parameter entities needed to use the OASIS table model and references (invokes) the OASIS XML Exchange (CALS) Table Model Module. This module has been modified to use a namespace prefix of “oasis” for all table elements, to permit both the OASIS Exchange (CALS) table models and XHTML-inspired table models to be used in one tag set. There is a separate Tag Library (https://jats.nlm.nih.gov/options/OASIS/tag-library/19990315/index.html) describing the OASIS elements, attributes, and parameter entities.
OASIS XML Exchange (CALS) Table Model Module (oasis-exchange.ent)
This is the OASIS XML Exchange (CALS) table model DTD fragment, modified to use the OASIS namespace and the “oasis” prefix. This module is invoked from the JATS OASIS XML Exchange (CALS) setup module.
The modules that define character entities and notations (all optional):
XML Special Characters Module
(parameter entity %xmlspecchars.ent;) Standard ISO XML special character entities used in this Tag Set.
Custom Special Characters Module
(parameter entity %chars.ent;) Custom special character entities created specifically for use in this Tag Set.
Notation Declarations Module
(parameter entity %notat.ent;) Container module for the Notation Declarations to be used with this Suite. These notations have been placed in their own module for easy expansion or replacement.
