Ethereum block description help

For example if you look here: [login to view URL] There is a data tree Data tree has a txs sub tree Some txs's have a call transfer and/or tokentransfer sub tree I need description of what each one means and values it could have. I tried looking through Whitepaper and others and I am not having any luck. I need official documentation ideally or as close to it. If you find me documentation from Ethereum dev that would be idea but so far I can only find bits and pieces from unofficial source. Thank you
