Abstract

RDFa Core 1.1 [RDFA-CORE] defines attributes and syntax for embedding semantic markup in Host Languages. This document defines one such Host Language. This language is a superset of XHTML 1.1 [XHTML11-2e], integrating the attributes as defined in RDFa Core 1.1. This document is intended for authors who want to create XHTML-Family documents that embed rich semantic markup.

Status of This Document

This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.

This is an early editors draft for discussion purposes. Once development is complete, if accepted by the W3C membership, this document will supercede the previous version. There are a number of substantive differences between this version and its predecessor, including:

  1. Inheritance of basic processing rules from [RDFA-CORE].
  2. The inclusion of an implementation of the markup language using XML Schema.
  3. The addition of @lang to be consistent with recent changes in [XHTML11-2e].

Members of the public are invited to send comments on this document to public-rdf-in-xhtml-tf@w3.org (with public archive).

A sample test harness is available. This set of tests is not intended to be exhaustive. Users may find the tests to be useful examples of RDFa usage. An implementation report lists several implementations of this specification tested during the Candidate Recommendation period. A community-maintained Wiki page includes subsequent updates.

This document was published by the RDFa Working Group as an Editor's Draft. If you wish to make comments regarding this document, please send them to public-rdfa-wg@w3.org (subscribe, archives). All feedback is welcome.

Publication as a Editor's Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.

Table of Contents

1. Introduction

XHTML+RDFa 1.1 is an XHTML family markup language. It extends the XHTML 1.1 markup language with the attributes defined in RDFa Core 1.1. The document also defines an XHTML Modularization-compatible [XHTML-MODULARIZATION11] module for the RDFa Core attributes in both XML DTD and XML Schema formats.

2. Conformance

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words must, must not, required, should, should not, recommended, may, and optional in this specification are to be interpreted as described in [RFC2119].

2.1 Document Conformance

A strictly conforming XHTML+RDFa document is a document that requires only the facilities described as mandatory in this specification. Such a document satisfies the following criteria:

  1. The document must conform to the constraints expressed in the schemas in Appendix B - XHTML+RDFa XML Schema and Appendix A - XHTML+RDFa Document Type Definition.

  2. The local part of the root element of the document must be html.

  3. The start tag of the root element of the document must explicitly contain a default namespace declaration for the XHTML namespace [XML-NAMES11]. The namespace URI for XHTML is defined to be http://www.w3.org/1999/xhtml.

    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  4. There should be a @version attribute on the html element with the value "XHTML+RDFa 1.1".
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml" 
    version="XHTML+RDFa 1.0"
    lang="en"
    xml:lang="en">
  <head>
    <title>Virtual Library</title>
  </head>
  <body>
    <p>Moved to <a href="http://example.org/">example.org</a>.</p>
  </body>
</html>

Note that in this example, the XML declaration is included. An XML declaration like the one above is not required in all XML documents. XHTML document authors should use XML declarations in all their documents. XHTML document authors must use an XML declaration when the character encoding of the document is other than the default UTF-8 or UTF-16 and no encoding is specified by a higher-level protocol.

XHTML+RDFa documents should be labeled with the Internet Media Type "application/xhtml+xml" as defined in [RFC3236]. For further information on using media types with XHTML family markup languages, see the informative note [XHTML-MEDIA-TYPES].

2.2 User Agent Conformance

A conforming user agent must support all of the features required in this specification. A conforming user agent must also support the User Agent conformance requirements as defined in XHTML Modularization [XHTML-MODULARIZATION11] section on "XHTML Family User Agent Conformance".

3. Additional RDFa Processing Rules

Documents conforming to the rules in the specification are processed according to [RDFA-CORE] with the following extensions:

4. XHTML+RDFa 1.1 Definition

The XHTML+RDFa 1.1 document type is a fully functional document type with rich semantics. It is a superset of [XHTML11-2e].

The XHTML+RDFa 1.1 document type is made up of the following XHTML modules. The elements, attributes, and content models associated with these modules are defined in "XHTML Modularization" [XHTML-MODULARIZATION11]. The elements are listed here for information purposes, but the definitions in XHTML Modularization should be considered authoritative.

Structure Module
body, head, html, title
Text Module
abbr, acronym, address, blockquote, br, cite, code, dfn, div, em, h1, h2, h3, h4, h5, h6, kbd, p, pre, q, samp, span, strong, var
Hypertext Module
a, and @href is available on all elements.
List Module
dl, dt, dd, ol, ul, li
Object Module
object, param
Presentation Module
b, big, hr, i, small, sub, sup, tt
Edit Module
del, ins
Bidirectional Text Module
bdo
Forms Module
button, fieldset, form, input, label, legend, select, optgroup, option, textarea
Table Module
caption, col, colgroup, table, tbody, td, tfoot, th, thead, tr
Image Module
img
Client-side Image Map Module
area, map
Server-side Image Map Module
Attribute ismap on img
Intrinsic Events Module
Events attributes
Metainformation Module
meta
Scripting Module
noscript, script
Stylesheet Module
style element
Style Attribute Module Deprecated
@style
Target Module
@target
Link Module
link
Base Module
base
Metainformation Attributes Module
@about, @content, @datatype, @typeof, @property, @rel, @resource, @rev, @vocab

XHTML+RDFa also uses the Ruby Annotation module as defined in [RUBY]:

Ruby Annotation Module
ruby, rbc, rtc, rb, rt, rp

This specification also adds the lang attribute to the I18N attribute collection as defined in [XHTML-MODULARIZATION11]. The lang attribute is defined in [HTML401]. When this attribute and the xml:lang attribute are specified on the same element, the xml:lang attribute takes precedence. When both lang and xml:lang are specified on the same element, they should have the same value.

There are no additional definitions required by this document type. An implementation of this document type as an XML Schema is defined in Appendix D, and as an XML DTD is defined in Appendix A.

5. Metainformation Attributes Module

The Metainformation Attributes Module defines the Metainformation attribute collection. This collection allows elements to be annotated with metadata throughout an XHTML-family document. When this module is included in a markup language, this collection is added to the Common attribute collection as defined in [XHTML-MODULARIZATION11].

5.1 Datatypes

Note that these datatypes are likely to be extended as the RDFa Core 1.1 spec matures.

Some of the attributes in this section use the following datatypes:

Data typeDescription
CURIE A Compact URI or curie.
CURIEs A whitespace separated list of CURIEs.
URIorCURIE A URI or a CURIE.
URIorCURIE A whitespace separated list of URIorCURIEs.
URIorSafeCURIE A URI or safe_curie.

Note that a specification of these data types in XML DTD and XML Schema is available in Appendix B.

5.2 Metainformation Attributes Collection

The following attributes are included in the attribute collection, and take values in the associated datatype:

Attributes Notes
about (URIorCURIE)  
content (CDATA)  
datatype (URIorCURIE) If not specified, then the default value is string as defined in [XMLSCHEMA-2].
typeof (URIorCURIEs)  
property (URIorCURIEs)  
rel URIorCURIEs See the reserved values list in XHTML Default Vocabulary Terms
resource (URIorCURIE)  
rev URIorCURIEs See the reserved values list in XHTML Default Vocabulary Terms
vocab URI A URI that defines the prefix to use when a CURIE is specified with no prefix and no colon.

An implementation of this module can be found in Appendix A.

5.3 XHTML Default Vocabulary Terms

Note that the values defined in this section may be removed from this document and placed in an external 'RDFa Profile' so that they can be maintained independent of the specification.

The list of reserved values for @rel and @rev are:

alternate
Designates alternate versions for a resource.
appendix
Refers to a resource serving as an appendix in a collection.
bookmark
Refers to a bookmark. A bookmark is a link to a key entry point within an extended document. The @title attribute may be used, for example, to label the bookmark. Note that several bookmarks may be defined for a document.
cite

Refers to a resource that defines a citation. In the following example, the cite is used to reference the book from which the quotation is taken:

As Gandalf the White said in 
<span rel="cite" resource="http://www.example.com/books/the_two_towers">
    The Two Towers
</span>,
<quote xml:lang="en">"The hospitality of 
your hall is somewhat lessened of late, Theoden King."</quote>

which would generate the following triples:

<> xhv:cite <http://www.example.com/books/the_two_towers> .
cite is also useful for referencing specifications: 
More information can be found in 
<span rel="cite" resource="http://www.w3.org/TR/REC-xml">[XML]</cite>.

which would generate the following triples:

<> xhv:cite <http://www.w3.org/TR/REC-xml> .
chapter
Refers to a resource serving as a chapter in a collection.
contents
Refers to a resource serving as a table of contents.
copyright
Refers to a copyright statement for the resource.
first
Refers to the first item in a collection (see also start and top).
glossary
Refers to a resource providing a glossary of terms.
help
Refers to a resource offering help (more information, links to other sources of information, etc.)
icon
Refers to a resource that represents an icon.
index
Refers to a resource providing an index.
last
Refers to the last resource in a collection of resources.
license
Refers to a resource that defines the license associated with a resource.
meta
Refers to a resource that provides metadata, for instance in RDF.
next
Refers to the next resource (after the current one) in an ordered collection.
p3pv1
Refers to a P3P Policy Reference File. See [[!P3P1.0]].
prev
Refers to the previous resource (before the current one) in an ordered collection.
role
Indicates the purpose of the resource. For some possible values, see [XHTML-VOCAB].
section
Refers to a resource serving as a section in a collection.
stylesheet
Refers to a resource acting as a stylesheet for a resource.
subsection
Refers to a resource serving as a subsection in a collection.
start
Refers to the first resource in a collection of resources. A typical use case might be a collection of chapters in a book.
top
Synonym for start.
up
Refers to the resource "above" in a hierarchically structured set.

A. XHTML+RDFa Document Type Definition

This appendix is normative.

This appendix includes an implementation of the XHTML+RDFa 1.0 language as an XML DTD. It is implemented by combining the XHTML 1.1 DTD with the XHTML Metainformation Attribute Module. This is done by using a content model module, and then a driver module. There are direct links to the various files, and the files are also contained in the "Gzip'd TAR" and "Zip" archives linked to at the top of this document. Please note that the files targeted by the "latest version" links may change slowly over time. See the W3C XHTML2 Working Group home page for more information.

<!-- XHTML+RDFa Document Model

     This module describes the groupings of elements that make up
     common content models for XHTML elements.

     XHTML has three basic content models:

         %Inline.mix;  character-level elements
         %Block.mix;   block-like elements, eg., paragraphs and lists
         %Flow.mix;    any block or inline elements

     Any parameter entities declared in this module may be used
     to create element content models, but the above three are
     considered 'global' (insofar as that term applies here).

     The reserved word '#PCDATA' (indicating a text string) is now
     included explicitly with each element declaration that is
     declared as mixed content, as XML requires that this token
     occur first in a content model specification.
-->
<!-- Extending the Model

     While in some cases this module may need to be rewritten to
     accommodate changes to the document model, minor extensions
     may be accomplished by redeclaring any of the three *.extra;
     parameter entities to contain extension element types as follows:

         %Misc.extra;    whose parent may be any block or
                         inline element.

         %Inline.extra;  whose parent may be any inline element.

         %Block.extra;   whose parent may be any block element.

     If used, these parameter entities must be an OR-separated
     list beginning with an OR separator ("|"), eg., "| a | b | c"

     All block and inline *.class parameter entities not part
     of the *struct.class classes begin with "| " to allow for
     exclusion from mixes.

B. XHTML+RDFa XML Schema

This appendix is normative.

This appendix includes an implementation of the XHTML+RDFa 1.0 language using XML Schema. It is implemented by combining the XHTML 1.1 Schema with the XHTML Metainformation Attribute Module. This is done by using a content model module, and then a driver module. There are direct links to the various files, and the files are also contained in the "Gzip'd TAR" and "Zip" archives linked to at the top of this document. Please note that the files targeted by the "latest version" links may change slowly over time. See the W3C XHTML2 Working Group home page for more information.

            XHTML Document Model 
            This module describes the groupings of elements/attributes 
            that make up common content models for XHTML elements. 
            XHTML has following basic content models: 
               xhtml.Inline.mix; character-level elements
               xhtml.Block.mix; block-like elements, e.g., paragraphs and lists
               xhtml.Flow.mix; any block or inline elements 
               xhtml.HeadOpts.mix; Head Elements 
               xhtml.InlinePre.mix; Special class for pre content model 
               xhtml.InlineNoAnchor.mix; Content model for Anchor 
            
            Any groups declared in this module may be used to create 
            element content models, but the above are considered 'global' 
            (insofar as that term applies here). XHTML has the
            following Attribute Groups 
               xhtml.Core.extra.attrib 
               xhtml.I18n.extra.attrib
               xhtml.Common.extra 
            
            The above attribute Groups are considered Global

C. Deployment Advice

This section is non-normative.

Documents written using the markup language defined in this specification can be validated using the DTD defined in Appendix A. If a document author wants to faciliate such validation, they may include the following declaration at the top of their document:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN"
    "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">

The XML Namespace document associated with the XHTML Family of markup languages uses the mechanism for transforming XHTML+RDFa documents into RDF as defined by [GRDDL]. Authors who want to be certain their documents are transformable by all [GRDDL] processors may also include a profile attribute on the head element that includes a reference to the XHTML vocabulary URI http://www.w3.org/1999/xhtml/vocab.
