The Ecore export from EA version 15 only include the navigable side of an association. This is different from EA 13 that included both sides of an association regardless of navigability. The lack of the non navigable side makes it impossible to check the cardinality for that side. Assume a 1 to 0..1 cardinality and the one side is the navigable one. As the 0..1 side is missing its cardinality cannot be checked.
How is navigability in Ecore intended to be described?
Is this an issue with the Ecore representation or with the EA 15 export?
Tanksful for answer.

Your questions (this one and the other) seem related to EMF in general, and how it relates to other modeling tools/standards. This forum is for Ecore Tools, which is a particular graphical modeler to EMF metamodels (Ecore models), not for general questions about EMF as a framework and meta-modeling language.
You may have more chance to get answers by asking in the main EMF forum at
