Abstract Context Model-driven Engineering (MDE) promotes the utilization of models as
primary artifacts in all software engineering activities. Therefore, mechanisms to ensure …

Abstract The Object Constraint Language (OCL) started as a complement of the UML
notation with the goal to overcome the limitations of UML (and in general, any graphical …

Assessment of the correctness of software models is a key issue to ensure the quality of the
final application. To this end, this paper presents an automatic method for the verification of …

The increasing popularity of MDE results in the creation of larger models and model
transformations, hence converting the specification of MDE artefacts in an error-prone task …

In model-driven engineering, models constitute pivotal elements of the software to be built. If
models are specified well, transformations can be employed for different purposes, eg, to …

Error checking is easy and inexpensive in the initial stages as compared to later stages due
to when the development cycle precedes the development cost and efforts also increase …

Models lie at the heart of the emerging model-driven engineering approach. In order to
guarantee precise, consistent, and correct models, there is a need for efficient powerful …

In this paper we propose a mapping from OCL to many-sorted first-order logic, called
OCL2MSFOL. This new mapping significantly improves our previous results in two key …

We present a formal calculus for operational QVT. The calculus is implemented in the
interactive theorem prover KIV and allows to prove properties of QVT transformations for …

The validation and the verification of conceptual schemas have attracted a lot of interest
during the last years, and several tools have been developed to automate this process as …
