Explanatory notes

From GSIM 1.1 “A Datum is the actual instance of data that was collected or derived. It is the value which populates one or more Data Points. A Datum is the value found in a cell of a table.” (https://statswiki.unece.org/display/GSIMclick/Datum ) A Datum could be copied to one or more datasets. DDI4 takes a little more formal (semiotic) description of a Datum using the Signification Pattern. See the attached example. NOTE: This is NOT datum from DDI3.2 (which is quite specific).
