\nLinked Data requirements are scary!
\nRDFa = RDF in attributes – way of integrating structured data into HTML pages – people can read page, machines can read data<\/p>\n

Example<\/p>\n

<html xmlns:foaf=”http:\/\/xmlns.com\/foaf\/0.1\/”>
\n<div about=”#person” typeof=:foaf:Person”>
\n<h2 property=”foaf:name”>Damian Steer<\/h2>
\n<\/div><\/p>\n

The attributes allow you to say what the data is that you are representing, data lives in the page – in this case div attributes say you are going to talk about a ‘person’ – saying it is a foaf:Person means external consumer will know it is the same type of thing as other foaf:Persons. h2 attribute say you have a foaf:name, and then contents of h2 is the name<\/p>\n

Tips:
\nAugment your HTML – don’t write RDF
\nIf you have more than two RDFa attributes on an element reconsider your design<\/p>\n

Who is using RDFa? Google (Rich Snippets uses RDFa and other stuff), Facebook (Open Graph Protocol – dumbed down RDFa), Yahoo (Search Monkey), Rotten Tomatoes<\/p>\n

RDFa 1.1
\n        Coming into html5
\n        Simplify prefixes
