Yahoo!'s plans to "open up" really started circulating at the beginning of this year. Not long after, Yahoo! Search announced its plans to support semantic mark-ups, specifically our crawler support for markups like RDFa and eRDF, as well as provided a glimpse into our open approach to search.
As Yahoo! prepares to support standards, like RDFa for example, we've continued to work closely with the best and brightest in the semantic markup community. We were thrilled to have Ben Adida visit the Sunnyvale campus a few weeks ago. Ben is a research fellow with the Center for Research on Computation and Society at the Harvard School of Engineering and Applied Sciences. He is also the Creative Commons representative to the W3C and chair of the RDF-in-HTML task force, focusing on bridging the semantic and clickable webs.
Ben was kind enough to submit himself to a barrage of questions on RDFa, its development and the opportunities it provides. Take a look and feel free to drop questions you have in the comments. We'll do our best to cycle them through to Ben.
