In the yaml representation of DAX we have
uses:

• file:
  lfn: f.b1
  metadata:
  size: "2048"
  size: "2048"
  type: output
  registerReplica: false
  stageOut: true

Some attributes are grouped under file
it will be good to flatten out(remove the file grouping), so that uses renders like this
uses:

• lfn: f.b2
  size: 2048
  metadata:
  createdBy: vahi
  type: output
  registerReplica: false
  stageOut: true
