Hello,

I have a question about how associations defined in a UML meta-model are
instantiated.
What happens to the multiplicities of an association  defined between
two meta-classes ?
For example an association  "ass" is defined between two metaclasses A
and B,
with multiplicity * (not explicitly defined):

        ass
|A| -----> |B|
          *

An instantiated model can be made of  a class A' (instance of the
metaclass A)
and a class B' (instance of B) and relation ass' between A' and B'.
Does the multiplicity of ass' have to be a specific number or it can
still remain unspecified with "*" ?

Thanks,
Simona.
