EPUB 3 Structural Semantics Vocabulary 1.1

This vocabulary, a part of EPUB® 3, defines a set of properties relating to the description of structural semantics of written works.

Introduction

Structural semantics add additional meaning about the specific structural purpose an HTML (or SVG) element plays. The [^/epub:type^] attribute [[epub-33]] is used to express domain-specific semantics in [=EPUB content documents=] and media overlay documents [[epub-33]], with the structural information it carries complementing the underlying vocabulary.

The applied semantics refine the meaning of their containing elements without changing their nature for assistive technologies, as happens when using the similar [^/role^] attribute [[html]]. The attribute does not enhance the accessibility of the content, in other words, only provides hints about the purpose.

Semantic metadata enriches content for use in publishing workflows and for author-defined purposes. It also allows reading systems to learn more about the structure and content of a document (e.g., to enable skippability and escapability in media overlay documents).

The [[epub-33]] specification defines a method for adding structural semantics using the attribute axis: instead of adding new elements, EPUB creators can append the epub:type attribute to existing elements to add the desired semantics. This document defines a set of property values, i.e., a vocabulary, that can be used for that purpose.

About this vocabulary

While the EPUB Structural Semantics vocabulary is generally host language agnostic, it has been constructed primarily to enable semantic inflection of elements in the HTML vocabulary.

The HTML usage context fields indicate contexts in HTML documents where the given property is considered relevant. EPUB creators may use the properties on HTML markup elements not specifically listed, but must ensure that the semantics they express represent a subset of the carrying element's semantics and do not attach an existing element's meaning to a semantically neutral element.

The DPUB-ARIA role fields indicate the [[dpub-aria-1.0]] roles that can alternatively be used with the [[html]] role attribute to improve accessibility. These roles may have more restrictive usage contexts, however, so may not be valid wherever the [^/epub:type^] attribute [[epub-33]] is used (e.g., roles are not allowed on the [[?html]] [^body^] element). Refer to [[html-aria]] for more information about where the roles are allowed.

When processing HTML documents, reading systems may ignore such non-compliant properties, unless their usage context is explicitly overridden or extended by the host specification.

The Usage details field, when present, identifies a specification that defines or utilizes the designated property. Authors are only required to follow these usage details if they are creating content that conforms to the specified specification, or if the rules apply to all EPUB publications. In all other cases, the properties may be used however needed.
