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.

HTML 5 defines the fifth major revision of the core language of the World Wide Web, HTML. "HTML 5 differences from HTML 4" describes the differences between HTML 4 and HTML 5 and provides some of the rationale for the changes. 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. [HTML5]

The ruby markup model currently described in the HTML specification is limited in its support for a number of features, notably jukugo and double-sided ruby, as well as inline ruby. 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'. It also defines an HTML element that embodies the semantics and function of the WAI-ARIA landmark role=main.

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.
