Hi, All,

I've found that there is no relationship in ecore, which exists in DSL.
How to represent it in ecore if wanted?

Thanks.

Hi, Wang,

Ecore's basic relationship construct is the EReference. It establishes
a link from an instance of one EClass to another.

If you are looking for something like the MOF association semantics,
have a look at Ed's thorough dissertation on his blog:

HTH,

Christian

Great, zeroOwnedEnds model shows clear way to resolve Relationship as one
EClass. It helps me a lot. Thanks again.
