The properties that can be asigned for a term might be defined under the terminology to which the term belongs. To insert a new property, open the form Terminology. You find the properties defined for a terminology in the base part of the form as shown below.

The properties that are defined in the terminology are then available for a term. Depending on the datatype set for a property in the terminology, you can either enter list, text, numeric or date values for a property of a term as in the example above numeric values for an age. For properties of the datatype list, an area for the entry of the dedicated (text) values will appear as shown below.

The values for a term will be restricted to the list of values (see below).
