| <link rel="profile" href="http://dublincore.org/documents/dcq-html/">
<link rel="schema.DC" href="http://purl.org/dc/elements/1.1/">
<meta name="DC.title" content="My Title">
<meta name="DC.description" content="My short description for the page.">
<meta name="DC.subject" content="one, two, three">
