Analysing Graph Transformation Rules through OCL
نویسندگان
چکیده
In this paper we present an approach to the analysis of graph transformation rules based on an intermediate OCL representation. We translate different semantics of rules into OCL, together with the properties of interest (like rule applicability, conflict or independence). The intermediate representation serves three purposes: (i) allows the seamless integration of graph transformation rules with the MOF and OCL standards, and enables taking into account meta-model and OCL constraints when verifying the correctness of the rules; (ii) permits the interoperability of graph transformation concepts with a number of standards-based model-driven development tools; and (iii) makes available a plethora of OCL tools to actually perform the rule analysis.

Model Transformation From VisualOCL to OCL Using Graph Transformation
In this paper we present a model transformation from a visual representation (VisualOCL) of the Object Constraint Language (OCL) to the textual one using graph transformation. Starting from VisualOCL diagrams, we show how their underlying abstract syntax can be modeled by typed attributed graphs and converted into an OCL string representation using graph transformation rules.
متن کاملOptimization Algorithms For OCL Compilers
Constraint handling is one of the most focused research field in both model validation and model transformation. Constraints are often simple topological conditions such as multiplicity checks, but the main strength of the constraint validation lies in the textual constraints defined in high-level languages. Object Constraint Language (OCL) is a wide-spread formalism to express model constraint...
متن کاملSynthesis of OCL Pre-conditions for Graph Transformation Rules
Graph transformation (GT) is being increasingly used in Model Driven Engineering (MDE) to describe in-place transformations like animations and refactorings. For its practical use, rules are often complemented with OCL application conditions. The advancement of rule post-conditions into pre-conditions is a well-known problem in GT, but current techniques do not consider OCL. In this paper we pr...
متن کاملNew Type Checking Rules for OCL (Collection) Expressions
The Object Constraint Language OCL is an integral part of UML, the Unified Modeling Language standard. It has been added to Rational’s UML core as a logic-based sublanguage for the definition of integrity constraints (invariants) on class diagrams as well as for the definition of preand postconditions of operations. Despite of the fact that OCL is called a statically typed language its type che...
متن کاملTranslating Essential OCL Invariants to Nested Graph Constraints Focusing on Set Operations
Domain-specific modeling languages (DSMLs) are usually defined by meta-modeling where invariants are defined in the Object Constraint Language (OCL). This approach is purely declarative in the sense that instance construction is not incorporated but has to added. In contrast, graph grammars incorporate the stepwise construction of instances by applying transformation rules. Establishing a forma...
