Either json or Soap to exchange data in my project?
Use JSON.
My argument is that JSON maps directly to and from native data types in common scripting languages.
If you use Python, then None <-> null, True <-> true, False <-> false, int/float <-> Number, str/unicode <-> String, list <-> Array and dict <-> Object. You feel right at home with JSON.
If you use PHP, there should be similar mappings.
XML is always a foreign language for any programming language except Scala.
