This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document. Completed Work have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the. Standards This specification defines the 5th major version, second minor revision of the core language of the World Wide Web: the Hypertext Markup Language HTML. In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

This specification defines rules and guidelines for adapting the RDFa Core 1. The rules defined in this specification not only apply to HTML5 documents in non-XML and XML mode, but also to HTML4 and XHTML documents interpreted through the HTML5 parsing rules. This document defines data categories and their implementation as a set of elements and attributes called the Internationalization Tag Set ITS 2. In addition to HTML5 and XML, algorithms to convert ITS attributes to RDFa and NIF are provided. This document proposes a set of CSS properties associated with the 'Ruby' elements. They can be used in combination with the Ruby elements of HTML. Group Notes HTML and RDFa Resource Description Framework in Attributes provides a set of markup attributes to augment visual information on the Web with machine-readable hints. In this Primer, we show how to express data using RDFa in HTML, and in particular how to mark up existing human-readable Web page content to express machine-readable data. Whereas the microdata specification describes a means of markup, the output format is JSON. HTML 5 defines the fifth major revision of the core language of the World Wide Web, HTML. This document may not provide accurate information as the HTML 5 specification is still actively in development. When in doubt, always check the HTML 5 specification itself. This specification addresses these issues by introducing new elements and changing the ruby processing model. Specific care has been taken to ensure that authoring remains as simple as possible. This document looks at a number of use cases involving ruby, and examines the pros and cons of a number of alternative approaches for meeting those use cases using the current HTML5 model, the XHTML Ruby Annotation model, and two other models. The aim is to clarify which use cases are supported by the existing markup models HTML5 or XHTML , and where they are not, provide suggestions about how the markup model could be adapted to support those use cases. Implementers and standards developers can then take this background information and the suggestions in this document to specify and implement a comprehensive markup model for ruby in HTML5. This specification is an extension to the HTML5 specification. It defines an element to be used for the identification of the main content area of a document. The main element formalises the common practice of identification of the main content section of a document using the id values such as 'content' and 'main'. This document is a strict subset of the HTML5 specification that omits user-agent UA implementation details. It is targeted toward Web authors and others who are not UA implementors and who want a view of the HTML specification that focuses more precisely on details relevant to using the HTML language to create Web documents and Web applications. This guide aims to help publishers and consumers of HTML data use it well. With several syntaxes and vocabularies to choose from, it provides guidance about how to decide which meets the publisher's or consumer's needs. It discusses when it is necessary to mix syntaxes and vocabularies and how to publish and consume data that uses multiple formats. It describes how to create vocabularies that can be used in multiple syntaxes and general best practices about the publication and consumption of HTML data. The HLink module defined in this specification provides XHTML Family Members with the ability to specify which attributes of elements represent Hyperlinks, and how those hyperlinks should be traversed, and extends XLink use to a wider class of languages than those restricted to the syntactic style allowed by XLink. The XHTML Role Attribute defined in this specification allows the author to annotate XML Languages with machine-extractable semantic information about the purpose of an element. Use cases include accessibility, device adaptation, server-side processing, and complex data description. The XHTML+SMIL profile defines a set of XHTML abstract modules that support a subset of the SMIL 2. Drafts Below are draft documents: , ,. Some of these may become Web Standards through the. Others may be published as Group Notes or become obsolete specifications. Proposed Recommendations The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems and for distribution for example as a format to reference from an HTML element. Timed text is textual information that is intrinsically or extrinsically associated with timing information. Candidate Recommendations This specification defines WebVTT, the Web Video Text Tracks format. Its main use is for marking up external text track resources in connection with the HTML element. While encodings have been defined to some extent, implementations have not always implemented them in the same way, have not always used the same labels, and often differ in dealing with undefined and former proprietary areas of encodings. This specification attempts to fill those gaps so that new implementations do not have to reverse engineer encoding implementations of the market leaders and existing implementations can converge. Other Working Drafts This specification defines the 5th major version, third minor revision of the core language of the World Wide Web: the Hypertext Markup Language HTML. In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability. HTML 5 defines the fifth major revision of the core language of the World Wide Web, HTML. This document describes the set of guiding principles used by the HTML Working Group for the development of HTML5. The principles offer guidance for the design of HTML in the areas of compatibility, utility and interoperability. Obsolete Specifications These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used. Retired This specification defines the 5th major revision of the core language of the World Wide Web: the Hypertext Markup Language HTML. In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability. This specification defines the Second Edition of XHTML 1. The semantics of the elements and their attributes are defined in the W3C Recommendation for HTML 4. These semantics provide the foundation for future extensibility of XHTML. Compatibility with existing HTML user agents is possible by following a small set of guidelines. This specification defines the HyperText Markup Language HTML , the publishing language of the World Wide Web. This specification defines HTML 4. In addition to the text, multimedia, and hyperlink features of the previous versions of HTML HTML 3. HTML 4 also takes great strides towards the internationalization of documents, with the goal of making the Web truly World Wide. It is designed to be appropriate for printing from mobile devices to low-cost printers that might not have a full-page buffer and that generally print from top-to-bottom and left-to-right with the paper in a portrait orientation. XHTML-Print is also targeted at printing in environments where it is not feasible or desirable to install a printer-specific driver and where some variability in the formatting of the output is acceptable. The XHTML Basic document type includes the minimal set of modules required to be an XHTML host language document type, and in addition it includes images, forms, basic tables, and object support. It is designed for Web clients that do not support the full set of XHTML features; for example, Web clients such as mobile phones, PDAs, pagers, and settop boxes. The document type is rich enough for content authoring. XHTML Basic is designed as a common base that may be extended. The goal of XHTML Basic is to serve as a common language supported by various kinds of user agents. A document that uses polyglot markup is document that is a stream of bytes that parses into identical document trees with the exception of the xmlns attribute on the root element when processed as HTML and when processed as XML. Polyglot markup that meets a well defined set of constraints is interpreted as compatible, regardless of whether they are processed as HTML or as XHTML, per the HTML5 specification. Concepts that have traditionally been difficult for machines to detect, like people, places, events, music, movies, and recipes, are now easily marked up in Web documents. While publishing this data is vital to the growth of Linked Data, using the information to improve the collective utility of the Web for humankind is the true goal. To accomplish this goal, it must be simple for Web developers to extract and utilize structured information from a Web document. This document details such a mechanism; an RDFa Application Programming Interface RDFa API that allows simple extraction and usage of structured information from a Web document. An XHTML+MathML+SVG profile is a profile that combines XHTML 1. An XHTML version of this document is conforming to this DTD. The HTML Working Group is chartered with the development of an extensible, sub-settable version of HTML that is compatible with XML. It is also chartered with the development of some extensions to HTML - notably in the area of forms. This group's current activities commenced in August 1998, and the group was rechartered in June 2000. The purpose of this document is to describe the activities of the HTML Working Group, define general milestones for each sub-project, and outline the inter-dependencies among the various deliverables.
