  This case comprises several primitive tasks that can be solved straight away
with most transformation tools. The aim is to cover the most important kinds of
primitive operations on models, i.e. create, read, update and delete (CRUD). To
this end, tasks such as a constant transformation, a model-to-text
transformation, a very basic migration transformation or diverse simple queries
or in-place operations on graphs have to be solved.
  The motivation for this case is that the results expectedly will be very
instructive for beginners. Also, it is really hard to compare transformation
languages along complex cases, because the complexity of the respective case
might hide the basic language concepts and constructs.
