Hi, PLZ,

Just because nobody answered on their free time over the week-end,
doesn't mean that nobody knows an answer. :-)

A link is an InstanceSpecification whose classifier is an Association.
If you don't have an association (but just a property typed by some
Class) then you can't have a link.

For each end of the association you will need a Slot whose value is an
InstanceValue referencing the InstanceSpecification at that end of the
link. These slots reference the corresponding member ends of the
association as their definingFeature.

Depending on whether or how many of the associated Classes have
navigable properties in this association, your InstanceSpecifications on
either end of the link may also have Slots defined by those ends, with
InstanceValues referencing the InstanceSpecification at the other end.

Even if you are not using the object diagramming tool from the UML2
Tools project, you might nonetheless want to use it to draw a diagram
representative of your scenario to see what it produces in the model ...

HTH,

Christian

Thanks Aot Christian for ur time and reply
I got ur approach which was useful for me, and with my expirements i found a simple approach for that,
1- Create a slot in the src end of the desired association: put the classifier as the type of that class (the src of the assoctation)
2- create an instance value and put the type and he instance the target class of the association

This will make direct link between the two insatces while ur will create an extra class for the association



Thanks again

wafaa
