Applies the HAL entity field normalization to an entity normalization.

The HAL normalization:

  • adds a 'lang' attribute to every translatable field
  • omits reference fields, since references are stored in _links & _embedded
  • omits empty fields (fields without value)

Parameters

array $normalization: An entity normalization.

Return value

array The updated entity normalization.
