  * @description Property display value is used for dashboard rendering, and the corresponding member unique id is

  * This class maps olap property display value to '.d' in identifier to make v2 query response algin with
  * current dashboard implementation so v1 and v2 queries can follow the same logic.
  *
  * @example The response identifiers with an olap property:
  * '1': {
  * 	'ihId': 1,
  * 	'd': 'Camping Equipment',<-corresponding member display value
  * 	'u': '[Sales (analysis)].[Products].[Products].[Product line]->[Products].[991]',<-corresponding member unique id
  * 	'Product line code': {<-property name
  * 		'v': 991<-property display value
  * 	}
  * }
  *
  * After process:
  * '1': {
  * 	'ihId': 1,
  * 	'd': 991,
  * 	'u': '[Sales (analysis)].[Products].[Products].[Product line]->[Products].[991]',<-corresponding member unique id
