[mdr-users] How does work the consistency rules in a metamodel?

Hi,

I have some questions about constraints and consistency rules. Does MDR
get to verify constraints like cardinality by itself? For example, the
metamodel Projects in MDR Web Site has 2 elements called Project and
ClassPath where One Project must have at least a ONE associated ClassPath.
But I get insert a Project instance without a ClassPath instance. Is there
any way to make the MDR verify this?

Thanks,

Luiz Felipe
