Definition

A «Mode» is a particular type of intrinsic property that has no structured value. Like qualities, modes are also individuals that existentially depend 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: A «Mode» cannot have an identity provider («Kind», «Collective», «Quality», «Relator», «Mode» and «Quantity») as its direct or indirect super-type.

C4: A «Mode» cannot have types that inherit identity («Subkind», «Role» and «Phase») as its direct or indirect super-type.

C5: A «Mode» cannot have types that aggregate individuals with different identity principles («Category», «RoleMixin», «PhaseMixin» and «Mixin») as its direct or indirect subtypes.

C6: As a rigid type, a «Mode» cannot have any anti-rigid type («Role», «RoleMixin», «Phase» and «PhaseMixin») as its direct or indirect super-type.
