Conceptset

Description

A Conceptset or Multi Select is a collection of concepts. Duplicates can never occur in the same collection and are filtered out.

Formatting

Concepts in single quotes, separated by a comma and enclosed with curly brackets {}.

{ 'Color'.'Orange', 'Color'.'Blue', 'Color'.'Red' }
/* a set of concepts with the colors Orange, Blue and Red */

{ } 
/* one empty set = not an unknown set, rather a known set with 0 concepts */

{ 'Color'.'Orange', 'Color'.'Blue' } + { 'Color'.'Orange', 'Color'.'Red' }
= { 'Color'.'Orange', 'Color'.'Blue', 'Color'.'Red' }
/* no duplicates when combining 2 sets with overlapping concepts */

Unknown

An unknown value can be written as UnknownConceptset

Remarks

A field that has a concept set value is called a "multi select" field.
