4、i ISO/IEC 2014 All rights reservedISO/IEC TS 30135-2:201 4(E) Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participat
5、e in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and
6、 non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The m
7、ain task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies cas
8、ting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, the joint technical committee may decide to publish an ISO/IEC Technical Specification (ISO/IEC TS), which represents an agreement between the members of the joint technical committee and
9、 is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/IEC TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/IEC TS is
10、 confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be hel
11、d responsible for identifying any or all such patent rights. ISO/IEC TS 30135 series were prepared by Korean Agency for Technology and Standards (as KS X 6070 series) with International Digital Publishing Forum and were adopted, under a special “fast-track procedure”, by Joint Technical Committee IS
12、O/IEC JTC 1, Information technology, in parallel with its approval by the national bodies of ISO and IEC.

22、eferences 1 Overview 1.1 Purpose and Scope This section is informative This specification, EPUB Publications 3.0, defines publication-level semantics and conformance requirements for EPUB 3, including the format of the Package Document and rules for how this document and other Publication Resources
23、are associated to create a conforming EPUB Publication. This specification is one of a family of related specifications that compose EPUB 3, the third major revision of an interchange and delivery format for digital publications based on XML and Web Standards. It is meant to be read and understood i
24、n concert with the other specifications that make up EPUB 3: The EPUB 3 Overview EPUB3Overview, which provides an informative overview of EPUB and a roadmap to the rest of the EPUB 3 documents. The Overview should be read first. EPUB Content Documents 3.0 ContentDocs30, which defines profiles of XHT
25、ML, SVG and CSS for use in the context of EPUB Publications. EPUB Open Container Format (OCF) 3.0 OCF3, which defines a file format and processing model for encapsulating a set of related resources into a single-file (ZIP) EPUB Container. EPUB Media Overlays 3.0 MediaOverlays30, which defines a form
26、at and a processing model for synchronization of text and audio. This specification supersedes Open Package Format 2.0.1 OPF2. Refer to EPUB3Changes for information on differences between this specification and its predecessor. 1.2 Terminology EPUB Publication (or Publication) A logical document ent
27、ity consisting of a set of interrelated resources and packaged in an EPUB Container, as defined by this specification and its sibling specifications. Publication Resource A resource that contains content or instructions that contribute to the logic and rendering of the EPUB Publication. In the absen
28、ce of this resource, the Publication might not render as intended by the Author. Examples of Publication Resources include the Package Document, EPUB Content Documents, EPUB Style Sheets, audio, video, images, embedded fonts and scripts. With the exception of the Package Document itself, Publication
29、 Resources must be listed in the manifest and must be bundled in the EPUB container file unless specified otherwise in Publication Resource Locations. Examples of resources that are not Publication Resources include those identified by the Package Document link element and those identified in outbou
30、nd hyperlinks that resolve outside the EPUB Container (e.g., referenced from an HTML5 a element href attribute). Foreign Resource A Publication Resource that is not a Core Media Type. A Foreign Resource requires at least one fallback, as defined in Restrictions and Fallbacks. Core Media Type Resourc
31、e A Publication Resource that is a Core Media Type and may therefore be included in the EPUB Publication without the provision of fallbacks. EPUB Content Document A Publication Resource that conforms to one of the EPUB Content Document definitions (XHTML or SVG). An EPUB Content Document is a Core M
32、edia Type, and may therefore be included in the EPUB Publication without the provision of fallbacks. XHTML Content Document An EPUB Content Document conforming to the profile of HTML5 defined in XHTML Content Documents ContentDocs30. XHTML Content Documents use the XHTML syntax of HTML5. SVG Content
33、 Document An EPUB Content Document conforming to the constraints expressed in SVG Content Documents ContentDocs30. EPUB Navigation DocumentA specialization of the XHTML Content Document, containing human- and machine-readable global navigation information, conforming to the constraints expressed in
34、EPUB Navigation Documents ContentDocs30. Scripted Content Document An EPUB Content Document that includes scripting or an XHTML Content Document that contains HTML5 forms elements. Refer to Scripted Content Documents ContentDocs30 for more information. Top-level Content Document An EPUB Content Docu
35、ment referenced directly from the spine Core Media Type A set of Publication Resource types for which no fallback is required. Refer to Publication Resources for more information. Package Document A Publication Resource carrying bibliographical and structural metadata about the EPUB Publication, as
36、defined in Package Documents. Manifestation The digital (or physical) embodiment of a work of intellectual content. Changes to the content such as significant revision, abridgement, translation, or the realization of the content in a different digital or physical form result in a new manifestation.
37、There may be many individual but identical copies of a manifestation, termed instances or items. The ISBN is an example of a manifestation identifier, and is shared by all instances of that manifestation. All instances of a manifestation need not be bit-for-bit identical, as minor corrections or rev
38、isions are not judged to create a new manifestation or work. Unique Identifier The Unique Identifier is the primary identifier for an EPUB Publication, as identified by the unique-identifier attribute. The Unique Identifier may be shared by one or many Manifestations of the same work that conform to
39、 the EPUB standard and embody the same content, where the differences between the Manifestations are limited to those changes that take account of differences between EPUB Reading Systems (and which themselves may require changes in the ISBN). The Unique Identifier is less granular than the ISBN. Ho
40、wever, significant revision, abridgement, etc. of the content requires a new Unique Identifier. Package Identifier The Package Identifier allows any instance of an EPUB Publication to be compared against another to determine if they are identical, different versions of the same Manifestation, or unr
41、elated. Refer to Package Identifier for more information. Manifest A list of all Publication Resources that constitute the EPUB Publication. Refer to manifest for more information. Spine An ordered list of Publication Resources, typically EPUB Content Documents, representing the default reading orde
42、r of the Publication. Refer to spine for more information. Media Overlay Document An XML document that associates the XHTML Content Document with pre-recorded audio narration in order to provide a synchronized playback experience, as defined in MediaOverlays30. Text-to-Speech (TTS) The rendering of
43、the textual content of an EPUB Publication as artificial human speech using a synthesized voice. EPUB Style Sheet (or Style Sheet) A CSS Style Sheet conforming to the CSS profile defined in EPUB Style Sheets ContentDocs30. Viewport The region of an EPUB Reading System in which the content of an EPUB
44、 Publication is rendered visually to a User. CSS Viewport A Viewport capable of displaying CSS-styled content. EPUB Container (or Container) The ZIP-based packaging and distribution format for EPUB Publications defined in OCF3. Author The person(s) or organization responsible for the creation of an
45、EPUB Publication, which is not necessarily the creator of the content and resources it contains. User An individual that consumes an EPUB Publication using an EPUB Reading System. EPUB Reading System (or Reading System) A system that processes EPUB Publications for presentation to a User in a manner
46、 conformant with this specification and its sibling specifications. 1.3 Conformance Statements The keywords “MUST“, “MUST NOT“, “REQUIRED“, “SHALL“, “SHALL NOT“, “SHOULD“, “SHOULD NOT“, “RECOMMENDED“, “MAY“, and “OPTIONAL“ in this document are to be interpreted as described in RFC2119. All sections
47、of this specification are normative except where identified by the informative status label “This section is informative“. The application of informative status to sections and appendices applies to all child content and subsections they may contain. All examples in this specification are informativ
48、e. 2 EPUB Publications This section defines conformance requirements for EPUB Publications and EPUB Reading Systems at the Publication level. Conformance requirements particular to specific Publication Resources and processing contexts are located in the specifications referenced herein. 2.1 Content
49、 Conformance An EPUB Publication must meet all of the following criteria: All Publication Resources All Publication Resources it contains must be represented in the Package Document (as defined in manifest), adhere to the constraints for Core Media Types and Fallback and be located as per Publication Resource Locations. The Package Document It must contain exactly one Package Document, which must conform to the content requirements defined in Package Document Content Conf
