title: What file-format is this?
body: <p>I've been using this file-format below as an alternative for flat-text files, and I'm wondering if there is a name for it...</p>
  
  <p>Say you have this data in a CSV:</p>
  
  <pre><code>FirstName,LastName,Email,UserName,Notes
  Bob,Smith,bsmith@email.com,bsmith,Bob likes chicken
  John,Doe,jdoe@email.com,jdoe,
  Steve,Jobs,STEVE@apple.com,STEVE,Steve Jobs likes things that start with "i"
  </code></pre>
  
  <p>In this "other" file format, there are 3 columns:</p>
  
  <ol>
  <li>Unique ID</li>
  <li>Attribute Name</li>
  <li>Value</li>
  </ol>
  
  <p>The above data would look like this:</p>
  
  <pre><code>bmsith@email.com,FirstName,Bob
  bmsith@email.com,LastName,Smith
  bmsith@email.com,Email,bmsith@email.com
  bmsith@email.com,UserName,bsmith
  bmsith@email.com,Notes,Bob likes chicken
  jdoe@email.com,FirstNameJohn
  jdoe@email.com,LastName,Doe
  jdoe@email.com,Email,jdoe@email.com
  jdoe@email.com,UserName,jdoe
  STEVE@apple.com,FirstName,Steve
  STEVE@apple.com,LastName,Jobs
  STEVE@apple.com,Email,STEVE@apple.com
  STEVE@apple.com,UserName,STEVE
  STEVE@apple.com,Notes,Steve Jobs likes things that start with "i"
  </code></pre>
  
  <p>I actually delimit on tab, but comma is easier to read for this. And in this example, any of the attributes could be used as a unique identifier. </p>
