“…They have in common that the model is translated into a formalism that has a well-defined semantics. Most approaches employ automated reasoning in the target formalism, for example, description logic [23], first-order logic [11], relational logic [19], constraint satisfaction problems [9], or propositional logic [26]. Others, such as [4], use interactive theorem proving.…”

Abstract. 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, e.g., to produce final code. However, it is important that models produced by a transformation from valid input models are valid, too, where validity refers to the metamodel constraints, often written in OCL. Transformation models are a way to describe this Hoare-style notion of partial correctness of model transformations using only metamodels and constraints. In this paper, we provide an automatic translation of declarative, rule-based ATL transformations into such transformation models, providing an intuitive and versatile encoding of ATL into OCL that can be used for the analysis of various properties of transformations. We furthermore show how existing model verifiers (satisfiability checkers) for OCL-annotated metamodels can be applied for the verification of the translated ATL transformations, providing evidence for the effectiveness of our approach in practice.

Abstract: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 much as possible. This is achieved, in general, by assessing whether the schema satisfies different kinds of desirable properties which ensure that the schema is correct. In this paper we describe AuRUS, a tool we have developed to analyze UML/OCL conceptual schemas and to explain their (in)correctness. When a property is satisfied, AuRUS provides a sample instantiation of the schema showing a particular situation where the property holds. When it is not, AuRUS provides an explanation for such unsatisfiability, i.e., a set of integrity constraints which is in contradiction with the property.

“…Unfortunately, reasoning on OCL is undecidable in general. Therefore, current verification tools either require user interaction with the verification procedure (e.g., HOL-OCL [6], based on the Isabelle theorem prover), restrict the OCL constructs that can be used when writing OCL expressions (e.g., [23], based on query containment checking techniques) or follow a bounded verification approach, where the search space is finite in order to guarantee termination. The bounds in the verification are set by limiting the number of instances and the restricting the attribute domains to explore during the verification.…”

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 notation) in terms of precisely specifying detailed aspects of a system design. Since then, OCL has become a key component of any model-driven engineering (MDE) technique as the default language for expressing all kinds of (meta)model query, manipulation and specification requirements. Among many other applications, OCL is frequently used to express model transformations (as part of the source and target patterns of transformation rules), well-formedness rules (as part of the definition of new domain-specific languages), or code-generation templates (as a way to express the generation patterns and rules).This chapter pretends to provide a comprehensive view of this language, its many applications and available tool support as well as the latest research developments and open challenges around it.
