Introduction

This document expands upon the XML Document Type Definition implementing the NISO Digital Talking Book Version 3-06.

Contributors:: Harvey Bingham <hbingham@acm.org>; George Kerscher <kerscher@montana.com>; Michael Moodie <mmoo@loc.gov>; Markup Specification Team <daisy-wt-must@svb.nl>

1. Purpose

The Digital Talking Book 3.0 provides the means to package a published book with the combination of professional narration, navigation into that narration, and the text of the book marked with tags to convey its structure, content, and metadata about the book and its structure.

The Document Type Definition (DTD) defines the allowable element types and their attributes that can be used to markup the text of the book sufficiently that textual material can be synchronized with the professionally narrated version of that book. The synchronization can permit concurrent display of the text being narrated, and the textual material can be searched to locate material desired for narration.

This application of XML is the next generation after the DAISY 2.0 DTD, for the Digital Audio-based Information SYstem. That application developed a Navigation Control Center (NCC) for synchronizing document structure with narration.

The NCC will become another XML application derived from the markup of documents tagged using the dtbook3 DTD. Richer structuring capability is one of the objectives of this DTD. The Synchronized Multimedia Integration Language (SMIL) 1.0 will be used.

Some HTML elements are omitted from dtbook3. HTML authoring tools may include many of the additional tags that are left out of dtbook3. Endtag markup, sometimes optional in HTML, are required for use with dtbook3, as any XML application requires endtags. The benefit of including endtags is that the tagged document has dependable structure.

The tools available for browsing HTML may be used with dtbook3 material, at the expense of discarding some specific tagging and attributes that are not part of HTML 4.0.

2. Document Tagging Content

A Digital Talking Book 3 document should begin with the XML processing instruction identifying the version of XML, and encoding, such as:

<?xml version="1.0" encoding="ISO-8859-1" ?>

The alternative encoding="UTF-8" is appropriate for supporting UNICODE, as is expected for systems supporting XML applications.

This is followed by the document type declaration, the DOCTYPE:

<!DOCTYPE dtbook3 PUBLIC


"-//NISO//DTD dtbook3.dtd//EN"
"http://www.loc.gov/nls/niso/dtbk3-06.dtd"

"dtbook3.dtd">

It identifies dtbook3 as the name of the root element, the first to occur in any document.

Note that the reference is to the latest version of the DTD. When a document is tagged to a particular version of the DTD, the following is the alternative, here referring to version 3-06.

<!DOCTYPE dtbook3 PUBLIC


"-//NISO//DTD dtbook3.dtd Version 3-06 1999-09-23//EN"
"http://www.loc.gov/nls/niso/dtbk3-06.dtd"

"dtbk3-06.dtd">

The ExternalID begins with PUBLIC and is followed by the formal public identifier, indicating

`-//`	unregistered
`NISO//`	owning organization
`DTD`	kind of external entity
`dtbook3.dtd`	possibly with version 3-06 and date.
`//EN`	the public text language is English.

Then comes the PUBLIC URI for the DTD, where it may be found on the internet. Note that the URI pointing to the public version is to this abbreviated version, not the extended version.

The third string identifies the SYSTEM (local) version of the DTD, in this form it is expected to be found in the same directory as this dtbook3 document, else find from the PUBLIC URI.

XML allows an internal subset of declarations (in "[...]" before the concluding ">" of the DOCTYPE declaration) that override or extend those of this DTD. Future modularization will likely use these to enable otherwise disabled marked sections for modules such as drama.

Element Usage Summary

Element	Description
`a`	contains an anchor, which is used in two ways: A name anchor identifies an exact position in a given document. A link anchor, when activated, "links to" (takes the user to) another place within that document or another document. [HTML 4.0]
`abbr`	designates an abbreviation, a shortened form of a word.
`acronym`	marks a word formed from key letters (usually initials) of a group of words. For example: UNESCO, NATO, XML.
`act`	is possible dtbook3 top-level of drama.
`address`	contains a location at which a person or agency may be contacted. [HTML 4.0]
`author`	identifies the writer of a given work.
`base`	contains the base URI from which local references start. It acts as an absolute URI that serves as the base URI for resolving relative URIs found within the document. It is an empty element that may appear only in <head>. [HTML 4.0]
`bdo`	is used in special cases where the automatic actions of the bidirectional algorithm would result in incorrect display. [HTML 4.0]
`blockquote`	indicates a quotation that is set off from the surrounding text by paragraph breaks. Compare with <q> which marks short, inline quotations. [HTML 4.0]
`bodymatter`	consists of the text proper of a book, as opposed to preliminary material (frontmatter) or supplementary information (rearmatter).
`book`	surrounds the entire content of the document, divided into frontmatter, bodymatter, and rearmatter. Metadata is not included in <book>, but is placed in <head>.
`br`	marks a forced line break. [HTML 4.0]
`caption`	describes a table. If used, it must follow immediately after the table start tag. [HTML 4.0]

`div`	is a generic container for subdivisions of a book. The level1 ... level6 hierarchy, or the <level> tag used recursively, should mark the major hierarchical structures of a book, while div is used in less formal circumstances or when for production purposes it is desired that a structure should be treated differently. The class attribute identifies the actual name (e.g., part, chapter, letter) of the structure it marks. Compare with <span> which is used in inline settings. [HTML 4.0]
`dl`	contains a definition list, usually consisting of pairs of terms <dt> and definitions <dd>. Any definition can contain another definition list. [HTML 4.0]

`level1`	is the highest level container of major divisions of a book. Used in frontmatter, bodymatter, and rearmatter to mark the largest divisions of the book (often chapters), inside which level2 subdivisions (often sections) may nest. The class attribute identifies the actual name (e.g., part, chapter, letter) of the structure it marks.
`level2`	contains subdivisions that nest within level1 divisions. The class attribute identifies the actual name (e.g., part, chapter, letter) of the structure it marks.
`level3`	contains subdivisions that nest within level2 subdivisions (e.g., subsections within sections). The class attribute identifies the actual name (e.g., part, chapter, letter) of the structure it marks.
`level4`	contains subdivisions that nest within level3 subdivisions. The class attribute identifies the actual name (e.g., part, chapter, letter) of the structure it marks.
`level5`	contains subdivisions that nest within level4 subdivisions. The class attribute identifies the actual name (e.g., part, chapter, letter) of the structure it marks.

`ol`	contains an ordered list (list items are numbered or lettered). [HTML 4.0]
`p`	contains a paragraph. [HTML 4.0]
`pagenum`	contains a page number from the print document, recorded as the first text object on a page. The"page" attribute allows three types of page numbering schemes to be identified: "normal" arabic numbering in the body of the book., "front" pages (from the frontmatter), and "special" pagination scheme such as hyphenated numbers in appendices.
`param`	provides a named property for <object>. [HTML 4.0]
`poem`	contains a poem
`prodnote`	contains language added to the alternative-format version by the producing organization; commonly used to provide verbal descriptions of visual elements such as charts, graphs, etc., supply operating instructions, or describe differences between the print book and the audio version.

`sidebar`	contains information supplementary to the main text and/or narrative flow and is often boxed and "floating" apart from the main text.
`span`	is a generic container for use in inline settings when no specific tag exists for a given situation. The class attribute may describe the nature of the text it marks (e.g., a typographical error). May be used to mark a class of items to which styles are to be applied. Compare with <div> which is used in block settings. [HTML 4.0]
`speaker`	is dtbook3 container for speaker identification.
`speech`	is dtbook3 container for speech by speaker.
`stage`	is dtbook3 stage instructions.

Element Descriptions

For each of the elements in the dtbk3-03.dtd in the order they occur in the DTD the following information is supplied:

<Element name>
Description, with suffix if from [HTML 4.0]
Contains: original element type declaration, and Expanded: if original has any parameter entities in its content model.
Occurs within: list of element names in which this element may (or must) occur directly, in their content models.
Attributes: Original: and Expanded: if there are parameter entities they are expanded.

Element Declarations are shown as:

<!ELEMENT elementname

Contains:
	`EMPTY` or original content model:
Expanded:
	content model with parameter entities expanded

>

EMPTY declared content denotes that the element has no explicit content. Instead its purpose is to mark a position, and to associate attribute values to that position. The XML-approved way to indicate the end-tag of such an element is by the special tag close ' />'. That leading space (after the end of the final quoted value for an attribute) is presumed by some browsers.

For example, using the EMPTY horizontal irule tag:: <hr title="horizontal rule purpose" />
or for backward compatibility the more common end tag form may be used:: <hr title="horizontal rule purpose"></hr>

Element content models are formed from a parenthesized list of names of other elements or parameter entities of the form %name; or #PCDATA, separated by connectors:

Connector	Use	Example
,	sequence	`(x,y)` is `x` followed by `y`
\|	alternative	`(x\|y)` is either `x` or `y`
(...)	grouping	`(x,(y\|z))` is `x` followed by either `y` or `z`

Individual names or groupings of them may have a following replicator (by default no replicator means one of:

Replicator	Use	Example
?	optional	`x?` means zero or one of `x`
*	optional and repeatable	`x*` means zero or more of `x`
+	Repeatable	`x+` means one or more of `x`
none	One only	`x` means just one `x`

#PCDATA is a special name allowing text. The only place that it can occur in a content model is first among alternatives:: (#PCDATA | x | y)+
means choose among one or more of x or y intermixed with text.

#PCDATA stands for "parsed character data", indicating that the content may include entities representing non-ASCII characters, intermixed with the ASCII characters. The form for referencing such entities is: &xHHHH;
where the HHHH denotes a Unicode hexidecimal code position.

Attribute List Declarations have one or more attributes. Each attribute has three parts: Name, Declared Value, and Default Value. They are shown as:

Name of attribute as it may appear in a document tag,in the form: name="value".

Declared value of attribute, of various types:

Attribute Type	Explanation
`ID`	identifier, formed from letters (case sensitive), digits, dash, underscore, and period.
`IDREF`	Value is one ID value
`IDREFS`	Values are one or more space-separated ID values
`CDATA`	character string, with the semantic meaning suggested by the parameter entity name.
(name1\|name2\|...)	Select at most one among the alternatives

Default value of attribute, of various kinds:

Default Value	Explanation
`#IMPLIED`	attribute and its value may be omitted, and if so, the meaning is up to the system.
`#REQUIRED`	attribute and its value must be included.
quoted value	One of the explicit names in the Declared value.

Hyperlinking:

Each element name in the <!Element elementname Contains: ... and Expanded: ... > is linked to its description.
Each parameter entity reference (%name;) in the Element and Attribute list is linked to the corresponding entry in the Parameter Entities Sorted section. Since they are expanded where they occur, the parameter entity reference links need not usually be followed.

Appendix C: Dublin Core Electronic Discovery Metadata The reference for the Dublin Core Version 1.0 is Dublin Core Metadata for Resource Discovery IETF RFC 2413 dated September 1998 http://info.internet.isi.edu/in-notes /rfc/files/rfc2413.txt The Dublin Core is a metadata element set intended to facilitate discovery of electronic resources. It was originally conceived for author-generated description of Web resources. It has attracted the attention of formal resource description communities such as museums, libraries, government agencies, and commercial organizations. In HTML 4.0 the fifteen names for the discovery concepts qualify their meaning. This set of names is fixed. They are specialized by associating to each occurrence of one of those names a value. The value is a string. The prefix for the name attribute form for Dublin Core is: <meta name="DC.xxx" value=\"...\"> It uses the prefix "DC." and no embedded spaces. for example: <meta name="DC.Title" value=\"Dublin Core Metadata for Resource Discovery\"> Name Content DC.Title Name of the resource. DC.Creator Person or organization primarily responsible for the intellectual content of the resource. DC.Subject Topic or keywords addressed by the work. DC.Description Textual description of content of the resource. DC.Publisher Agent or agency responsible for making the resource available. DC.Contributor Person or organization other than Creator(s) who have made other significant but secondary intellectual contributions to the work. DC.Date Publication date, using one of the forms (yyyy, yyyy-mm, yyyy-mm-dd). DC.Type Category of the resource, such as home page, novel, poem, or dictionary, selected from enumerated list. DC.Format Physical manifestation of the resource, such as Postscript file or Windows executable file. DC.Identifier String or number used to uniquely identify the resource. DC.Source Objects, either print or electronic, from which this resource is derived, if applicable. DC.Language Language of the intellectual content. DC.Relation Relationship to other resources. DC.Coverage Spatial locations and temporal durations characteristic of the resource. DC.Rights A rights-management statement or linking identifier to it or service providing it. For example: <meta name="DC.Title" content="The Bible"> During transition to the single form, a browser should accept the alternative prefixes: "DC:", "dc:", or "dc." Include as many separate meta elements as are appropriate, and repeat the same Name for each distinct and appropriate content. For a repeated name, the source order should be preserved in their contents. The http-equiv attribute can replace name for use when documents are retrieved using HTTP. Servers can use the value to create a header in the HTTP response sent back to the browser. The HTML meta attribute: name="keywords" content="keyword1,keyword 2, ..." is an HTML convention to aid search engines. Dublin Core does not recognize this use. Instead it uses separate meta: name="DC.Subject" content="keyword1" name="DC.Subject" content="keyword 2" name="DC.Subject" content="..." The HTML meta lang attribute can be used to identify the language for the content, say of an author's name. The scheme attribute may further qualify the content, as to indicate the kind of DC.Identifier, such as scheme="ISSN" scheme="ISBN" scheme="L/C" etc. Go to Table of Contents
