Physician places an order 
A physician enters an order for a chest x-ray. He works in a huge multi
campus hospital with multiple radiology departments.
We have an RDF doc describing properties of the departments and relations
between them.
-Campus A is a children's hospital
-Radiology department B is part of hospital A
-Radiology department C is specialized in examinations of the type D
-Urgent requests should be handled on the same campus (if specialization
-Requesting department E has as first collaboration choice: department F
-Specialization precedes first choice
-There is a schedule for after work hours
Etc ....
The poor physician is agnostic of these rules. The only thing he wishes is
placing his order and see where this examination will be executed, given the
facts: Patient is child, examination = Chest x-ray and not urgent, referring
department is 'E', ordering time = today 10 pm, etc...
I presume the query is not fired by the physician but by a 'routing engine'
being called by the physician's application. So, maybe the name of the use
case should be 'routing engine routes order'.
The result of the query should be a list of departments, sorted on aptness
to execute the order.
The query should give the constraints and ask for a resolution (no matter
how complex this system in practice might be)
This use case shows the need to add constraints in the query and shows the
need for not only querying for information but also for a resolution of a
problem (which might be the same thing)
Hope this helps.
