Happend on: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" itemscope="itemscope" itemtype="http://schema.org/Person"> <head> <meta name="author" itemprop="name" content="Some Name" /> <meta name="description" itemprop="description" content="Some Description" /> But specification "A vocabulary and associated APIs for HTML and XHTML"(http://www.w3.org/TR/html5/microdata.html#names:-the-itemprop-attribute) say: "Every HTML element may have an itemprop attribute specified ..." 65438 1 mike 2012-03-13 05:46:34 +0000 The microdata spec defines some further restrictions - http://dev.w3.org/html5/md/#content-models "If a meta element has an itemprop attribute, the name, http-equiv, and charset attributes must be omitted, and the content attribute must be present." So you need to omit the name attribute
