Complex query example: 

”Find Input Parameters that are not assigned to an Input Port”
From a folder or system, find the related parameters and check if the
parameter is not the complying end of a Receive or PG Receive link: if
so, flag the parameter as an error.OpenMBEE MMS

Validation rules with the VIATRA Query Language (VQL)
• Deadlock states
• Detect potential deadlock states
• Trivial case: a potential deadlock
state is a

Simple state which 

has incoming transitions but 

no outgoing ones.
• Composite states: If no sub-state
has a transition that leaves the
composite state’s region(s).
Transition leaving the
