Twitter cards
Another example of the use of injecting metadata inside HTML content is given by Twitter Cards. The metadata added in your pages allow Twitter to enrich tweets linked to your content by adding a “Card” visible to all of the people viewing the tweet and enriching the user experience with additional multimedia content.
RDFa.info Play tool
The site rdfa.info provides many resources for embedding linked data in HTML.
You can, for instance, play with a tool to see in real time the modifications you make to an RDFa+HTML code... Play with it to add, for example, a creator property to a document!
