title: marker metadata?
body: <p>I have more of an approach question, than a code question.</p>
  
  <p>Let's say I have 2 webpages (page a &amp; page b) on the same domain.</p>
  
  <p>User is on page a. They click a link. I'd like to take the user to page b, and open an info window.</p>
  
  <p>My thought was to add some sort of id, or data attribute to a marker, and then, when the user gets to page B, an event fires opening the correct point/infowindow.</p>
  
  <p>I read something about marker metadata:   marker.metadata = {type: "point", id: 1};</p>
  
  <p>But I am confused at to what this actually does. In the resulting html/map, is the marker an element with this id?</p>
  
  <p>Thanks in advance for any shedding of the light!</p>
