 A constraint on the number of times that an attribute group may be included in the same concept definition or expression.


  • Cardinality constraints are represented by square brackets containing a minimum value value represented as an integer, optionally followed by two dots and a maximum value represented as an integer or as an asterisk *.
    • If the maximum is omitted then the maximum cardinality is the same as the minimum cardinality.
    • If the maximum is an asterisk * the maximum cardinality is unlimited.
  • Attribute group cardinality is NOT the same as attribute in group cardinality.
