  6. An Example Problem: the need to mark-up address information semantically. <div class="adr"> <abbr class="type" title="dom">U.S.</abbr> <span class="type">home</span> address, for <abbr class="type" title="postal">mail</abbr> and <abbr class="type" title="parcel">shipments</abbr>: <div class="street-address">123 Main Street</div> <span class="locality">Any Town</span>, <span class="region">CA</span> <span class="postal-code">91921-1234</span> </div> Microformatsare easily human-readable when rendered in a browser.

Categories People and Organizations • hCard <divclass="vcard"><a class="urlfn" href="http://tantek.com/">TantekÇelik</a></div> • Geo • enables publishers to add geodata about the location of a person, place, event, or thing to a page <span class="geo"> <span class="latitude">27.976628</span>, <span class="longitude"> å 86.933302</span> </span> • XFN (XHTML Friends Network) is a simple way to represent human relationships using hyperlinks • indicate their relationship(s) to the people in their blogrolls simply by adding a 'rel' attribute to their <a href> tags <a href="http://jeff.example.org" rel="friend met"> • other rel : coworker, neighbor, child

  8. Categories • hRecipe • markup for creating meals, drinks, food-based items • identify individual food related concepts • required property: fn – fromatted name and an ingredient <span class = “hrecipe”> <span class = “fn ingredient”> sugar </span> </span>
