puts JSON::Validator.validate!(poaster_instance_schema, data, :strict => true,:insert_defaults => true)            # ==> true

the side2 data can be either a null representing no side2 information (this can happen for Shareative of type video) or it can contain an object for image Shareative type

so essentially a side2 json would look like this

shareative : {
   ....  ....  ....  ..
  // for video Shareative type
   side2: null
} 


// Or it can be like this for Image Shareative type with Image Data


shareative : {
   ....  ....  ....  ..
   side2: {
    type: 'image',
    data: {
      // for image data
      url: 'http://some url',
      thumb: 'http://somethumb url' 
     }
  }
} 




// or like this it  for Image Shareative type with Text Data


shareative : {
   ....  ....  ....  ..
   side2: {
    type: 'text'
    data: {
      // for text data
      side2_text_data: 'some text data',
      side2_link_url: 'http://some link url',
      side2_link_text: 'some link text' 
     }
  }
