The History of Information, by David Siegel on VimeoDavid Siegel, author of 4 books about the web, presents his new 8-minute video on the history and future of information. Using a fast pace and fun graphics, Siegel introduces us to the next wave of innovation with two key concepts he claims will affect $10 trillion of commerce worldwide: pull and the semantic web. This concise introduction to the wider concepts of his new book on the topic, Pull, will guide you in making the shift from push to pull. Caution: this video will make you think about potential changes you might want to make to your business model and the way you do business.

RDFa PrimerToday's web is built predominantly for human consumption. Even as machine-readable data begins to appear on the web, it is typically distributed in a separate file, with a separate format, and very limited correspondence between the human and machine versions. As a result, web browsers can provide only minimal assistance to humans in parsing and processing web data: browsers only see presentation information. We introduce RDFa, which provides a set of XHTML attributes to augment visual data with machine-readable hints. We show how to express simple and more complex datasets using RDFa, and in particular how to turn the existing human-visible text and links into machine-readable data without repeating content.W3C
W3C RDFa Working GroupThe mission of the RDFa Working Group, part of the Semantic Web Activity is to support the developing use of RDFa for embedding structured data in Web documents in general. The Working Group will publish W3C Recommendations to extend and enhance the currently published RDFa 1.0 documents, including an API. The Working Group will also support the HTML Working Group in its work on incorporating RDFa in HTML5 and XHTML5.

RDFa in XHTML: Syntax and Processing 1.1RDFa is a specification for attributes to express structured data in any markup language. This document specifies how to use RDFa with XHTML. The rendered, hypertext data of XHTML is reused by the RDFa markup, so that publishers don't need to repeat significant data in the document content. The underlying abstract representation is RDF [RDF-PRIMER], which lets publishers build their own vocabulary, extend others, and evolve their vocabulary with maximal interoperability over time. The expressed structure is closely tied to the data, so that rendered data can be copied and pasted along with its relevant structure.RDFa Working Group

This Wiki is the main working area of the Working Group, that has started its work in February 2010.
