title: Default NFC commands
body: <p>I'm trying to figure out how one encodes an NFC tag so that it provokes default behavior on NFC enabled devices akin to what's depicted in this youtube video:

  <p>My assumption is that the NFC tag must contain the instruction for the listening device to use whatever means it can to follow a link (?)... I'm guessing of course, but that would make sense.  My bigger question is where do I find the full spec for what default commands are possible via NFC.</p>
  
  <p>TIA</p>
