RDFa in XHTML is a w3c standard. Microdata is mentioned as a HTML 5 API. My questions are:

  1. Is microdata also a w3c standard? If yes, why we need 2 similar standards?

  2. People say using microdata is simpler than RDFa. Except for this, what are the main differences between these two?

Thank you in advance Manoj
