A class expression

As well as a named class, it is possible to define classes of individuals based on these class constructors.

Variants

Class(Class)

A named class

Some

An existential relationship

This is the anonymous class of individuals i, which have the relationship o to a class expression ce. Every individual in i must have this relationship to one individual in ce.

Fields of Some

o: ObjectProperty
ce: Box<ClassExpression>

Only

A universal relationship

This is the anonymous class of individuals i where all individuals which are related by o are instances of ce. This does not imply that the i necessarily has any relation r.

Fields of Only

o: ObjectProperty
ce: Box<ClassExpression>

And

The boolean and

The class of individuals which are individuals of all these classes.

Fields of And

o: Vec<ClassExpression>

Or

The boolean or

The class of individuals which are individuals of any of these classes.

Fields of Or

o: Vec<ClassExpression>

Not

The boolean not

The class of individuals which are not individuals of any of these classes.

Fields of Not

ce: Box<ClassExpression>
