Archiving and Interchange DTD

This DTD was created from the Journal Archiving and Interchange DTD Suite, which provides a set of XML modules that define 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).

The Suite of Modules

The intent of this DTD Suite is to preserve the intellectual content of journals independent of the form in which that content was originally delivered. The Suite has been written as a set of XML DTD modules, each of which is a separate physical file. No module is an entire DTD by itself, but these modules can be combined into a number of different DTDs.

The Archiving and Interchange DTD may be used as is, or the Suite can be used to construct DTDs for authoring and archiving journal articles as well as DTDs for transferring journal articles from publishers to archives and between archives. Details on creating DTDs from the Suite are available in the Tag Library. Although the full Suite was developed to support electronic production, the structures should be adequate to support some print production as well.

NCBI/NLM also created the Journal Publishing DTD from the Suite. The Publishing DTD is a prescriptive subset of the Archiving and Interchange DTD optimized for the authoring and initial XML tagging of journal material. PubMed Central is encouraging the use of the Journal Publishing DTD to define submitted content.

[Note: NCBI/NLM also created a DTD for the submission of citations and abstracts for MEDLINE/PubMed that predated this Suite full-text effort. If you want to submit citations and abstracts to NLM for inclusion in PubMed/MEDLINE, use the PubMed Journal Article DTD. Detailed information is available from the PubMed web site: Information for Publishers re: XML Tagged Data.]

Using the Suite

These DTDs and the Suite are in the public domain. An organization that wants to create its own DTD from the Suite may do so without permission from NLM.

The Suite has been set up to be extended using a new DTD file and a new DTD-specific customization module to redefine the many Parameter Entities. Do not modify the Suite directly or redistribute modified versions of the Suite.

In the interest of maintaining consistency and clarity for potential users, NLM requests:

Documentation

Introduction	An introduction to the content of the Tag Library, to the design philosophy and intended usage of the Archiving and Interchange DTD Suite, and to the Journal Archiving and Interchange DTD.
Elements Section	Descriptions of the elements used in the Journal Archiving and Interchange DTD and DTD Suite modules.
Attributes Section	Descriptions of the attributes in the DTD modules.
Parameter Entity Section	Names (with occasional descriptions) and contents of the Parameter Entities in the DTD modules.
Context Table	Listings of where each element may be used. All elements are given in a simple alphabetical list. There is a single table for the elements from all the Suite modules that are called from the DTD.
Document Hierarchy Diagrams	Tree-like graphical representations of the content of many elements. This can be a fast visual way to determine the structure of an article or of any element within an article.
Index by Tag Name	Index of element descriptions, alphabetically by tag name (element-type name).
Index by Element Name	Index of element descriptions, alphabetically by element name (the longer, more descriptive name).
DTD Section	Copies of the Journal Archiving and Interchange DTD, its customization module, and the full Archiving and Interchange DTD Suite of XML DTD modules described in the Tag Library.

Getting the Files

Updates

Version

Version 1.1 was released on November 5, 2003. A detailed explaination of the changes from version 1.0 is available in the General Introduction to the v1.1 Tag Library.

W3C Schema Version

A W3C Schema has been generated from the DTD. The Schema version describes the same content model as the DTD. Information is available on the W3C Schema page.

Working Group and Secretariat

To keep the DTD relevant to the publishing and archiving communities, NLM has created the XML Interchange Structure Working Group. This group advises NLM on recommended changes in and/or additions to the tagset. The first meeting of the Working Group was held on August 18, 2003. The meeting notes are available as a Word document (working-group/AITWG-08-18-2003.doc).

NLM has contracted with Mulberry Technologies, Inc. of Rockville, MD to act as Archiving and Interchange Tagset Secretariat. The Secretariat will collect the feedback to be discussed by the Working Group and will maintain the files and documentation.

Feedback

Any suggestions for changes to the Tagset or documentation should be made through the Journal Article Tag Set Comment Form at the Mulberry Technolgies site.

Related DTDs

The Journal Publishing DTD, a prescriptive DTD optimized for the authoring and initial XML tagging of journal material for PubMed Central, was created from the Suite also.

Tools

NLM has created an XSL transform to HTML for previewing content in the Archiving and Interchange DTD and a Cascading Style Sheet to support it.

Commercial Tools that have been written for the DTDs are also available on the Tools page.

XML Information

Links to general information on XML, XSLT, Unicode™, and XLink are available on the XML Resources page.

Acknowledgments

NLM thanks Mulberry Technologies, Inc. and Inera, Inc. for their expert advice and the intense document analysis that was required to create this library of DTD modules for archiving and content interchange.

NLM also thanks the Harvard University Libraries, both for proposing that a draft archiving NLM DTD for life sciences journals be extended to accommodate journals in all disciplines and for sponsoring Inera's collaboration with other DTD authors in completing Version 1.0. The Andrew W. Mellon Foundation provided support for these important contributions.
