Input vs output formats for groups

[ghost]

The object representation of groups appear to be different between the format requires for sending messages, and the format received on the other end. For example, a sent group will be

groups: [
      {
        index: 453,
        delim: 447,
        entries: [
          {
            447: 'D',
            448: 'demo-9',
            452: '3'
          },
          {
            447: 'D',
            448: 'demo-8',
            452: '1'
          }
        ]
      },
...
    ]

But on the received side, it will be

groups: { 
     '453':
      [ { tags: { '447': 'D', '448': 'demo-9', '452': '3' } },
        { tags: { '447': 'D', '448': 'demo-8', '452': '1' } } 
      ] 
}

Are these formats documented somewhere? Is there a library to convert one to the other if I want to compare a sent message to the corresponding received message on the other side?

Thanks!

It is a bit confusing to send and receive messages...we are stuck in deadline time. it would be really helpful to us if you provide a sample for send and receiving messages.
