W3C Announces Three New RDFa Recommendations

World Wide Web Consortium logoThe W3C announced today that three specifications have reached recommendation status:

HTML+RDFa 1.1:

RDFa 1.1 Core – Second Edition
http://www.w3.org/TR/2013/REC-rdfa-core-20130822/

XHTML+RDFa 1.1 – Second Edition
http://www.w3.org/TR/2013/REC-xhtml-rdfa-20130822/

As the W3C website explains, “The last couple of years have witnessed a fascinating evolution: while the Web was initially built predominantly for human consumption, web content is increasingly consumed by machines which expect some amount of structured data. Sites have started to identify a page’s title, content type, and preview image to provide appropriate information in a user’s newsfeed when she clicks the ‘Like’ button. Search engines have started to provide richer search results by extracting fine-grained structured details from the Web pages they crawl. In turn, web publishers are producing increasing amounts of structured data within their Web content to improve their standing with search engines.”

“A key enabling technology behind these developments is the ability to add structured data to HTML pages directly. RDFa (Resource Description Framework in Attributes) is a technique that allows just that: it provides a set of markup attributes to augment the visual information on the Web with machine-readable hints. ”

Manu Sporny, the editor of the HTML+RDFa 1.1 specification, told us that, “The release of RDFa 1.1 for HTML5 establishes it as the first HTML-based Linked Data technology to achieve recognition as an official Web standard by the World Wide Web Consortium.” Read more

BREAKING: Schema.org announces intent to support RDFa Lite!

Last month, we reported on the new RDFa 1.1 Lite proposal by Ben Adida. In our recent podcast on Schema.org with guest Ramanathan V. Guha, we touched on the topic of RDFa Lite as well.

Today, schema.org spokesperson Dan Brickley posted that “we’re pleased to give advance notice of a new way of adopting schema.org’s structured data vocabulary. W3C’s RDF Web Applications group are right now putting the finishing touches to the latest version of the RDFa standard. This work opens up new possibilities also for developers who intend to work with schema.org data using RDF-based tools and Linked Data, and defines a simplified publisher-friendly ‘Lite’ view of RDFa.”

Introduction to: RDFa 1.1 Lite

[Editor’s Note: In our most recent SemanticLink podcast with special guest R.V. Guha, we mentioned RDFa 1.1 Lite, proposed by Ben Adida at last month’s Schema.org workshop. Thanks to Manu Sporny for sharing the following look at RDFa 1.1 Lite.]

Summary: RDFa 1.1 Lite is a simple subset of RDFa consisting of the following attributes: vocab, typeof, property, rel, about and prefix.

During the schema.org workshop, a proposal was put forth by RDFa’s resident hero, Ben Adida, for a stripped down version of RDFa 1.1, called RDFa 1.1 Lite. The RDFa syntax is often criticized as having too much functionality, leaving first-time authors confused about the more advanced features. This lighter version of RDFa will help authors easily jump into the Linked Data world. The goal was to create a very minimal subset that will work for 80% of the folks out there doing simple markup for things like search engines. Read more
