Turn basic TourML example into JSON

[Ambrosiani]

Let's start with turning this into JSON…

<?xml version="1.0" encoding="UTF-8"?>
  <tourml:Tour xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:tourml="http://tapintomuseums.org/TourML"
    tourml:id="org.tapintomuseums.example.tour">
    
    <tourml:Asset tourml:id="video-1">
      <tourml:Source tourml:uri="video.mov">
    </tourml:Asset>
    
    <tourml:Stop tourml:id="stop-1">
      <tourml:Title>A Video Stop</tourml:Title>
      <tourml:AssetRef tourml:id="video-1" />
    </tourml:Stop>
    
  </tourml:Tour>
