Definition

A «Mode» is a particular type of intrinsic property that has no structured value. Like qualities, modes are also individuals that existentially dependen on their bearers. Types stereotyped as «Mode» are also rigid.

You can find some examples of modes below:

Constraints

C1: Every «Mode» must be (directly or indirectly) connected to an association end of at least one «characterization» relation.

C2: The multiplicity of the characterized end (opposite to the Mode) must be exactly one. Therefore, the following examples are forbidden.

C3: Modes cannot have as ancestors the following types: «Kind», «Quantiy», «Collective», «Subkind», «Role», «RoleMixin», «Phase», «Relator», «Mode», «Quality».

C4: Modes cannot have as descendants the following types: «Kind», «Quantiy», «Collective», «RoleMixin», «Category», «Mixin», «Relator», «Mode», «Quality».
