====== Generator - DataSet Meta Generator ======




===== About =====

A ''data set meta generator''  is a [[data-supplier|column data generator]] that returns a meta column (third column) from a parent data set column (ie with a [[:docs:generator:data-set|data set]] or [[docs:generator:entity|entity]] generator)




===== Example =====

For example, in the region [[docs:generator:entity|entity]], you have rows that contains:
  * a `code` column
  * a `name` column

With:
  * the data set generator (ie [[entity|entity]] or [[docs:generator:data-set|data set]]), you may return the `name`
  * the data set meta generator, you may return the `code`
