description
Microformats allow you to extend the limited semantics of HTML, thus allowing for a richer web of data. By embedding microformats into HTML it is possible to use the semantic meaning to extract unambiguous data from the web that can then be used in other applications. Microformats focus on how people are already publishing their data online. This session focuses on the more technical aspects of microformats, how they interact with other Semantic Web technologies such as GRDDL and SPARQL, along with a look at browser plugins to detect microformats and browser integration.

Microformats + GRDDL = RDF
With important applications such as
connecting microformats to the
Semantic Web, GRDDL is a mechanism to
extract RDF statements from suitable
XHTML and XML content using programs
such as XSLT transformations. GRDDL
allows powerful mash-ups at very low cost.

SHELVING CATEGORY1. WEB DEVELOPMENT
JOHN ALLSOPPForeword by Tantek Çelik
Use rich semantics in your markup to make it machine-readable as well as human-readable
Make your websites “mashup-ready” for a new generation of web applications
Understand this fast-growing technology through this book’s real-world examples, case studies, tools, and much more
MMicroformats burst onto the scene a couple of years ago and are fast becoming an essential tool for all professional web designers and developers. Imagine being able to integrate all of your web-based contact details, tagged articles, and geographical information seamlessly in web and desktop applications, without having to add anything extra to your websites except a little specialized HTML markup.
Microformats provide a more formalized technology for adding commonly used semantics (such as contact details, location, and reviews) to today’s Web. Unlike XML or the Semantic Web, microformats use ubiquitous technologies like HTML and XHTML, existing developer skills, and current web tools, and, perhaps most important, they work in all of today’s web browsers.
This book is a comprehensive guide to microformats. It explores why, in Bill Gates’s words, “We need microformats”; how microformats work; and the kinds of problems microformats help solve. The book covers every current microformat, with complete details of the syntax, semantics, and uses of each, along with real-world examples and a comprehensive survey of the tools available for working with them. The book also features case studies detailing how major web content publishers such as Yahoo put microformats to work in their web applications.
Written by one of the Web’s best-known educators, John Allsopp,Microformats: Empowering Your Markup for Web 2.0 will help you painlessly get up to speed with this exciting technology. Empowering Your Markup for Web 2.0
