GDI Models related dimensions of through member of set and technique, add to model?

[Habennin]

GDI uses 'technique' on attribute assignment and 'member of' on dimensions to create sets of dimensions and measurement events.

The technique thing is done in linked.art we could add.

Member of set is not. We could add but also then question, is the set just a node in that object or do we have to create a set entity 'the set of h x w dimension of x object'?
