Google introduced a new enhancement called Rich Snippets in May 2009, giving searchers new ways to filter results and adding new types of data to the search results themselves. The feature is based on technologies including one designed at CWI: RDFa.

Rich Snippets

Rich Snippets, which is a partnership between Google and certain publishers, including CNET, is a feature to display information from Web pages within the box that encompasses a search result. Google is backing open standards called RDFa and Microformats that allow Web publishers to highlight aspects of their Web page to show in the search results.

RDFa 

CWI researcher Steven Pemberton and colleague Mark Birbeck proposed RDFa in 2004 in the HTML Working Group at W3C, and this later got expanded into a task force that combined the HTML working group and the Semantic Web Working Groups of which the CWI's Ivan Herman is the Activity Lead, and includes representatives from Creative Commons, IBM, and other companies. This group finally produced the  "RDFa Syntax and Processing" specification in October 2008. Since then adoption of RDFa has been great, including by US and UK government sites, Yahoo search, and now by Google.
