   The F# [JSON Type Provider](JsonProvider.html) is built on top of an efficient JSON parser written
  -in F#. The parser is based on a JSON parser available in [F# 3.0 Sample Pack](http://fsharp3sample.codeplex.com), 
  -but F# Data adds simple API that can be used to access values dynamically.

   When working with well-defined JSON documents, it is easier to use the 
   [type provider](JsonProvider.html), but in a more dynamic scenario or when writing
  
positive.code: 
  The following example shows how to process the sample JSON value:
  *)
  open FSharp.Data.Json.Extensions
  
  // Print name and birth year
  
negative.code: and the collection of data points, we use pattern matching and match the `value`
  against the `JsonValue.Array` constructor:
  *)
  
  match value with
  | JsonValue.Array [| info; data |] ->
      // Print overall information
