Version 1.1

[Updated versions of the Tag Suite have been released. The current version is available here.]

Version 1.1 of the Journal Archiving and Interchange DTD is a fully backward compatible revision of the Journal Archiving and Interchange Tag Suite. That is, all documents that were valid according to version 1.0 of the Tag Sets will also be valid according to version 1.1.

The Tag Suite was changed based on experience using the Tag Sets. Some users have been converting articles tagged according to other DTDs into Archiving and Interchange articles and found that they had to lose information (such as semantic identification of some sections) in the transformation. The changes to the Tag Suite are largely to allow preservation of such information.

W3C XML Schemas Available

In addition to DTDs, W3C XML Schemas are now available for each Tag Set. These are intended to be used with XML tools that cannot read DTDs but the schemas are not intended for maintenance.

Changes to the Entire Suite

• Media Object—Added a new element, <media>, that has the same content as <graphic> and can be used wherever <graphic> can be used, but indicates a Media Object, such as an animation or a movie.
• Journal Title (Full)—Added a new optional repeatable element Journal Title (Full) (<journal-title>) to the journal metadata, just before the abbreviated title.
• Label (of a Figure, Reference, Etc.)—Added optional element <label> to the front of the models of the following elements. These labels are to be treated as format over-rides and documented accordingly. They should NOT be used in the ordinary course of tagging.
  
  • <aff>
  • <array>
  • <author-notes>
  • <chem-struct>
  • <corresp>
  • <def-item>
  • <list-item>
• Named Special (Subject) Content—The previous <named-content> element was a small phrase-level structure, intended to surround words or phrases in the text and provide semantic tagging that was beyond the elements in the Tag Suite.
  Its model was expanded to include most of the other phrase-level structures, including the Display Class Elements and Inline Display Class Elements.
• Table Data Cell (XHTML table model) and Table Header Cell (XHTML table model)—Modified content models of <td> and <th> to include Phrase Class Elements (currently <named-content>).
• Array (Simple Tabular Array)—Modified content model of <array> to permit multiple <graphic> and <media> elements.
• Private Character (Custom or Unicode)—Modified content model of <private-char> to permit multiple <inline-graphic> elements.
• Alternate Form of Graphic, Media Object, Etc.—Added alternate-form-of attribute to permit an alternate form of certain elements. There may be a graphic form of an element as well as a tagged form, a TeX form as well as a tagged form, different resolutions of the same graphic, etc. (This attribute should not to be confused with the attribute Alternate Version of a Graphic. Unlike alt-version which simply indicates whether an alternate version exists, alternate-form-of provides linkage between various forms of an object.)
  Elements include most of the Display Class Elements, the math elements, and the table elements, as well as a number of inline display elements:
  
  • <array>
  • <chem-struct>
  • <graphic>
  • <inline-graphic>
  • <media>
  • <supplementary-material>
  • <disp-formula>
  • <inline-formula>
  • <mml:math>
  • <tex-math>
  • <table>
  • <inline-supplementary-material>
  (Display Class Elements not included are <boxed-text>, <chem-struct-wrapper>, <fig>, <fig-group>, <table-wrap>, and <table-wrap-group>.)
• Mime Type and Mime Subtype—Added optional mimetype and mime-subtype attributes to <graphic>, <inline-graphic>, <media>, <inline-supplementary-material>, and <supplementary-material>. Value is a list of the valid mimetypes.
• Type of Named Content—Added an optional content-type attribute to the following structures as a way to preserve any semantic intent of their original tagging:
  
  • <ack>
  • <array>
  • <boxed-text>
  • <chem-struct>
  • <chem-struct-wrapper>
  • <fig-group>
  • <inline-supplementary-material>
  • <p>
  • <speech>
  • <statement>
  • <supplementary-material>
  • <table>
  • <table-wrap>
  (Elements <def-list>, <fig>, <list>, <preformat>, and <sec> already had designated attributes for preserving semantic content.)
• Identifier—Attributes of type ID added to:
  
  • <ack>
  • <address>
  • <alt-text>
  • <array>
  • <chem-struct>
  • <corresp>
  • <def-item>
  • <disp-quote>
  • <ext-link>
  • <inline-formula>
  • <inline-graphic>
  • <inline-supplementary-material>
  • <institution>
  • <long-desc>
  • <named-content>
  • <notes>
  • <p>
  • <speech>
  • <table>
  • <verse-group>
  • <xref>
  (Elements <def-list>, <fig>, <list>, <preformat>, and <sec> already had designated attributes for preserving semantic content.)
• Type of Target—Added a target-type attribute to the element Target of an Internal Link to say why there is a target in a document at this point.
• Version of the DTD—Changed fixed value of dtd-version attribute to "1.1".
