title: How can I validate a JSON string against a schema programmatically?
body: <p>Are there simple libraries out there (.NET and Java) that are able to validate a JSON string given a schema definition?</p>
  
  <p>It should work similar to how XML can be validated using XSD.</p>
  
  <p><b>EDIT:</b> I need .NET <i>and</i> Java libraries. Thanks to darin for the .NET link!</p>
