Description

ref https://github.com/apache/arrow/pull/1829#discussion_r179248743

Currently our Traits are not loyal to https://arrow.apache.org/docs/metadata.html.

For example, we nest `Field`s in the `DataType` (aka `type`) attribute of the parent Field (rather than having the type be `Struct` and a separate `Children` parameter)

 

Is this OK, assuming that we can read and write accurate schemas? Or should we move towards having the Schema trait be consistent with the metadata spec?
