HTML  Browsers  

•  RDF  can  be  serialized  in  RDFa  •  Have  you  heard  of  – Yahoo’s  Search  Monkey  

– Google  Rich  Snippets?  •  They  are  consuming  RDFa

Because  there  is  life  beyond  ten  blue  links  

Google  and  Yahoo  are  starRng  to  crawl  RDFa!  

The  SemanRc  Web  is  a  reality!

•  Yahoo  is  crawling  data  that  is  in  RDFa  and  Microformats  under  a  specific  vocabularies    – FOAF  – GoodRelaRons  – …  

•  Google  is  crawling  RDFa  and  Microformats  that  use  the  Google  vocabulary  

•  How  much  of  this  is  Linked  Data    –  I  don’t  know
