The
Object Role Modeling language
(
ORM
2) is nowadays the most widespread fact-based conceptual modeling language in the business world. Recently, it has been proposed an encoding of the core fragment of
ORM
2 (called
ORM
2
zero
) into the description logic
$\mathcal{ALCQI}$
, allowing the use of reasoning technologies in the analysis of the schemas. A number of services has been defined there based on the FO semantics of
ORM
2. On the other hand, in many application domains there is a need for the formalization and modeling of
defeasible information
and
non-monotonic
reasoning services. Here we formalize a possible way of introducing non-monotonic reasoning into
ORM
2 schemas, enriching the language with special set of new constraints.
