Model transformation is one of the pillars of model-driven engineering (MDE). The increasing complexity of systems and modelling languages has dramatically raised the complexity and size of model transformations as well. Even though many transformation languages and tools have been proposed in the last few years, most of them are directed to the implementation phase of transformation development. In this way, even though transformations should be built using sound engineering principles---just like any other kind of software---there is currently a lack of cohesive support for the other phases of the transformation development, like requirements, analysis, design and testing. In this paper, we propose a unified family of languages to cover the life cycle of transformation development enabling the engineering of transformations. Moreover, following an MDE approach, we provide tools to partially automate the progressive refinement of models between the different phases and the generation of code for several transformation implementation languages.

In November 2000, the OMG made public the MDAinitiative, a particular variant of a new global trend called MDE (Model Driven Engineering). The basic ideas of MDA are germane to many other approaches such as generative programming, domain specific languages, model-integrated computing, generic model management, software factories, etc. MDA may be defined as the realization of MDE principles around a set of OMG standards like MOF, XMI, OCL, UML, CWM, SPEM, etc. MDE is presently making several promises about the potential benefits that could be reaped from a move from code-centric to model-based practices. When we observe these claims, we may wonder when they may be satisfied: on the short, medium or long term or even never perhaps for some of them. This paper tries to propose a vision of the development of MDE based on some lessons learnt in the past 30 years in the development of object technology. The main message is that a basic principle (“Everything is an object”) was most helpful in driving the technology in the direction of simplicity, generality and power of integration. Similarly in MDE, the basic principle that “Everything is a model” has many interesting properties, among others the capacity to generate a realistic research agenda. We postulate here that two core relations (representation and conformance) are associated to this principle, as inheritance and instantiation were associated to the object unification principle in the class-based languages of the 80's. We suggest that this may be most useful in understanding many questions about MDE in general and the MDA approach in particular. We provide some illustrative examples. The personal position taken in this paper would be useful if it could generate a critical debate on the research directions in MDE.

UML, and other object-oriented approaches to system specification and design, are increasingly popular in industry. Many attempts have been made to formalise either the notations, the system models produced using these notations, or both. However, there have been no attempts to compare the expressiveness of the formal approaches. This paper compares Z and Object-Z approaches to object-oriented formalisation. The Z approaches reflect different formalisation goals (a formal model of the system, a formal model of a diagrammatic object-oriented model). The Object-Z approach produces compact formal models, but imposes a particular semantic interpretation on the UML notations.

Model-driven software development, today's state-of-the-art approach to the design of software, can be applied in various domains and thus demands a variety of domain-specific modelling languages. The specification of a domain-specific modelling language's syntax and semantics can in turn be specified based on models, which represent the approach of metamodelling as a special form of language engineering. The latest version of the unified modelling language 2 (UML 2) and its subset the meta object facility 2 (MOF 2) provide sufficient support for metamodelling, a modelling language's abstract syntax. Furthermore, based on the description of the abstract syntax, a language's static semantics can simply be specified by the object constraint language (OCL) as UML/MOF's natural constraint language, whereas the description of an MOF compliant language's dynamic semantics is still not covered. The authors try to close this gap by integrating MOF/OCL with graph transformations for the specification of dynamic aspects of modelling languages and tools. The formalisation of such an integration is non-trivial because of the fact that UML/MOF 2 offer a rather unusual and sophisticated association concept (graph model). Although there are many approaches, which formalise graph transformations in general and first approaches that offer a precise specification of the semantics of the association concepts of UML/MOF 2, there is still a lack in bringing both together. Here, the authors close this gap by formalising graph transformations that work on a UML/MOF 2 compatible graph model.

QVT is the standard language sponsored by the OMG to specify model-to-model transformations. It includes three different languages, being QVT-relations (QVT-R) the one with higher-level of abstraction. Unfortunately, there is scarce tool support for it nowadays, with incompatibilities and disagreements between the few tools implementing it, and lacking support for the analysis and verification of transformations. Part of this situation is due to the fact that the standard provides only a semi-formal semantics for QVT-R. In order to alleviate this situation, this paper provides a semantics for QVT-R through its compilation into coloured Petri nets. The theory of coloured Petri nets provides useful techniques to analyse transformations (e.g. detecting relation conflicts, or checking whether certain structures are generated or not in the target model) as well as to determine their confluence and termination given a starting model. Our semantics is flexible enough to permit the use of QVT-R specifications not only for transformation and check-only scenarios, but also for model matching and model comparison, not covered in the original standard. As a proof of concept, we report on the use of CPNTools for the execution, debugging, verification and validation of transformations, and on a tool chain (named Colouring) to transform QVT-R specifications and their input models into the input format of CPNTools, as well as to export and visualize the transformation results back as models.
|||Perdita Stevens. A simple game-theoretic approach to checkonly QVT relations. Software & Systems Modeling, 12(1):175--199, Feb 2013. [ bib | DOI ]
The QVT Relations (QVT-R) transformation language allows the definition of bidirectional model transformations, which are required in cases where two (or more) models must be kept consistent in the face of changes to either or both. A QVT-R transformation can be used either in checkonly mode, to determine whether a target model is consistent with a given source model, or in enforce mode, to change the target model. A precise understanding of checkonly mode transformations is prerequisite to a precise understanding of enforce mode transformations, and this is the focus of this paper. In order to give semantics to checkonly QVT-R transformations, we need to consider the overall structure of the transformation as given by when and where clauses, and the role of trace classes. In the standard, the semantics of QVT-R are given both directly, and by means of a translation to QVT Core, a language which is intended to be simpler. In this paper, we argue that there are irreconcilable differences between the intended semantics of QVT-R and those of QVT Core, so that no translation from QVT-R to QVT Core can be semantics-preserving, and hence no such translation can be helpful in defining the semantics of QVT-R. Treating QVT-R directly, we propose a simple game-theoretic semantics. We demonstrate its behaviour on examples and show how it can be used to prove an example result comparing two QVT-R transformations. We demonstrate that consistent models may not possess a single trace model whose objects can be read as traceability links in either direction. We briefly discuss the effect of variations in the rules of the game, to elucidate some design choices available to the designers of the QVT-R language.

QVT-R is the standard Object Management Group bidirectional transformation language. In previous work, we gave a precise game-theoretic semantics for the checkonly semantics of QVT-R transformations, including the recursive invocation of relations which is allowed and used, but not defined, by the QVT standard. In this paper, we take up the problem of enforce semantics, where the standard attempts formality, but at crucial points lapses into English. We show that our previous semantics can be extended to enforce mode, giving a precise semantics taking the standard into account.

The railway interlocking system, being a safety-critical system, has achieved importance in the railway industry. Advanced technologies are being applied for its modelling, preventing collision and derailing of trains and at the same time allowing efficient movement of trains. In this study, we have applied Z notation by constructing a specification of the critical components of moving block interlocking. Graphs are used for modelling static components and are then integrated with Z to describe its entire state space. At first a real topology is transferred to a model topology in graph theory and then the critical components of the railway network, for example, tracks, switches, crossings and level crossing, are formalised. These components are integrated to define the static part of the system and then dynamic components, the state space of the static part, trains and controls, are integrated to describe the complete system. Formal specification of the system is given using Z and the model is analysed and validated using Z/EVES tool.

Specification plays a vital role in software engineering to facilitate the development of highly dependable software. Various techniques may be used for specification work. Z is a formal specification language that is based on a strongly-typed fragment of Zermelo-Fraenkel set theory and first-order logic to provide for precise and unambiguous specifications. While diagrammatic specification languages may lack precision, they may, owing to their visual characteristics be a lucrative option for advocates of semi-formal specification techniques. In this paper we investigate to what extent formal constructs, e.g. Z may be transformed into diagrammatic notations. Several diagrammatic notations are considered and combined for this purpose.

Formal methods (such as interactive provers) are increasingly used in software engineering. They offer a formal frame that guarantees the correctness of developments. Nevertheless, they use complex notations that might be difficult to understand for unaccustomed users. On the contrary, visual specification languages use intuitive notations and allow to specify and understand software systems. Moreover, they permit to easily generate graphical interfaces or editors for Domain Specific Languages (DSLs) starting from a meta-model. However, they suffer from a lack of precise semantics. We are interested in combining these two complementary technologies by mapping the elements of the one into the other.

Model transformation lies at the very core of model-driven engineering, and a large number of model transformation languages and tools have been proposed over the last few years. These tools can be used to develop, transform, merge, exchange, compare, and verify models and metamodels. In this paper, we present a comprehensive catalog of existing metamodel-based transformation tools and compare them using a qualitative framework. We begin by organizing the 60 tools we identified into a general classification based on the transformation approach used. We then compare these tools using a number of particular facets, where each facet belongs to one of six different categories and may contain several attributes. The results of the study are discussed in detail and made publicly available in a companion website with a capability to search for tools using the specified facets as search criteria. Our study provides a thorough picture of the state-of-the-art in model transformation techniques and tools. Our results are potentially beneficial to many stakeholders in the modeling community, including practitioners, researchers, and transformation tool developers.

The Unified Modeling Language (UML) is rapidly emerging as a de-facto standard for modelling OO systems. Given this role, it is imperative that the UML needs a well-defined, fully explored semantics. Such semantics is required in order to ensure that UML concepts are precisely stated and defined. In this paper we motivate an approach to formalizing UML in which formal specification techniques are used to gain insight into the semantics of UML notations and diagrams and describe a roadmap for this approach. The authors initiated the Precise UML (PUML) group in order to develop a precise semantic model for UML diagrams. The semantic model is to be used as the basis for a set of diagrammatical transformation rules, which enable formal deductions to be made about UML diagrams. A small example shows how these rules can be used to verify whether one class diagram is a valid deduction of another. Because these rules are presented at the diagrammatical level, it will be argued that UML can be successfully used as a formal modelling tool without the notational complexities that are commonly found in textual specification techniques.
|||Artur Boronat and José Meseguer. An algebraic semantics for MOF. Formal Aspects of Computing, 22(3):269--296, May 2010. [ bib | DOI ]
In model-driven development, software artifacts are represented as models in order to improve productivity, quality, and cost effectiveness. In this area, the meta-object facility (MOF) standard plays a crucial role as a generic framework within which a wide range of modeling languages can be defined. The MOF standard aims at offering a good basis for model-driven development, providing some of the building concepts that are needed: what is a model, what is a metamodel, what is reflection in the MOF framework, and so on. However, most of these concepts are not yet fully formally defined in the current MOF standard. In this paper we define a reflective, algebraic, executable framework for precise metamodeling based on membership equational logic (mel) that supports the MOF standard. Our framework provides a formal semantics of the following notions: metamodel, model, and conformance of a model to its metamodel. Furthermore, by using the Maude language, which directly supports mel specifications, this formal semantics is executable. This executable semantics has been integrated within the Eclipse modeling framework as a plugin tool called MOMENT2. In this way, formal analyses, such as semantic consistency checks, model checking of invariants and LTL model checking, become available within Eclipse to provide formal support for model-driven development processes.

This paper proposes a novel approach to the formal definition of UML semantics. We distinguish descriptive semantics from functional semantics of modelling languages. The former defines which system is an instance of a model while the later defines the basic concepts underlying the models. In this paper, the descriptive semantics of class diagram, interaction diagram and state machine diagram are defined by first order logic formulas. A translation tool is implemented and integrated with the theorem prover SPASS to enable automated reasoning about models. The formalisation and reasoning of models is then applied to model consistency checking.

Few tools are available to help with the difficult task of validating that a Z specification captures its intended meaning. One tool that has been proven to be useful for validating specifications is the Alloy Analyzer, an interactive tool for checking and visualising Alloy models. However, Z specifications need to be translated to Alloy notation to make use of the Alloy Analyzer. These translations have been performed manually so far, which is a cumbersome and error-prone activity. The aim of this paper is to explore to what extent this process can be automated.

QVT Relations (QVT-R) is the standard language proposed by the OMG to specify bidirectional model transformations. Unfortunately, in part due to ambiguities and omissions in the original semantics, acceptance and development of effective tool support has been slow. Recently, the checking semantics of QVT-R has been clarified and formalized. In this paper we propose a QVT-R tool that complies to such semantics. Unlike any other existing tool, it also supports meta-models enriched with OCL constraints (thus avoiding returning ill-formed models), and proposes an alternative enforcement semantics that works according to the simple and predictable “principle of least change”. The implementation is based on an embedding of both QVT-R transformations and UML class diagrams (annotated with OCL) in Alloy, a lightweight formal specification language with support for automatic model finding via SAT solving.

This paper provides a semantics for the UML-RSDS (Reactive System Development Support) subset of UML, using the real-time action logic (RAL) formalism. We show how this semantics can be used to resolve some ambiguities and omissions in UML semantics, and to support reasoning about specifications using the B formal method and tools. We use `semantic profiles' to provide precise semantics for different semantic variation points of UML. We also show how RAL can be used to give a semantics to notations for real-time specification in UML. Unlike other approaches to UML semantics, which concentrate on the class diagram notation, our semantic representation has behaviour as a central element, and can be used to define semantics for use cases, state machines and interactions, in addition to class diagrams.

A model transformation verification task may involve a number of different transformations, from one or more of a wide range of different model transformation languages, each transformation may have a particular transformation style, and there are a number of different verification properties which can be verified for each language and style of transformation. Transformations may operate upon many different modelling languages. This diversity of languages and properties indicates the need for a suitably generic framework for model transformation verification, independent of particular model transformation languages, and able to provide support for systematic procedures for verification across a range of languages, and for a range of properties. In this paper we describe the elements of such a framework, and apply this framework to some example transformation verification problems. The paper is novel in covering a wide range of different verification techniques for a wide range of MT languages, within an integrated framework.

The Model Driven Architecture (MDA) is an approach to develop software based on different models. There are separate models for the business logic and for platform specific details. Moreover, code can be generated automatically from these models. This makes transforma- tions a core technology for MDA and for model-based software engineering approaches in general. Query/View/Transformation (QVT) is the transformation technology recently proposed for this purpose by the OMG. Triple Graph Grammars (TGGs) are another transformation technology proposed in the mid-nineties, used for example in the FUJABA CASE tool. In contrast to many other transformation technologies, both QVT and TGGs declaratively define the relation between two models. With this definition, a transformation engine can execute a transformation in either direction and, based on the same definition, can also propagate changes from one model to the other. In this paper, we compare the concepts of the declarative languages of QVT and TGGs. It turns out that TGGs and declarative QVT have many concepts in common. In fact, QVT-Core can be mapped to TGGs. We show that QVT-Core can be implemented by transforming QVT-Core mappings to TGG rules, which can then be executed by a TGG transformation engine that performs the actual QVT transformation. Furthermore, we discuss an approach for mapping QVT-Relations to TGGs. Based on the semantics of TGGs, we clarify semantic gaps that we identified in the declarative languages of QVT and, furthermore, we show how TGGs can benefit from the concepts of QVT.

In model-based testing, one of the biggest decisions taken before modelling is the modelling language and the model analysis tool to be used to model the system under investigation. UML, Alloy and Z are examples of popular state-based modelling languages. In the literature, there has been research about the similarities and the differences between modelling languages. However, we believe that, in addition to recognising the expressive power of modelling languages, it is crucial to detect the capabilities and the weaknesses of analysis tools that parse and analyse models written in these languages. In order to explore this area, we have chosen four model analysis tools: USE, Alloy Analyzer, ZLive and ProZ and observed how modelling and validation stages of MBT are handled by these tools for the same system. Through this experiment, we not only concretise the tasks that form the modelling and validation stages of MBT process, but also reveal how efficiently these tasks are carried out in different tools.

Z is a well-defined and well-known specification language. Unfortunately, it takes significant expertise to use existing tools (such as theorem provers) to automatically check properties of Z specifications. Because Alloy is substantially similar to Z and the Alloy Analyzer offers a relatively simple method of model checking, we believe that Alloy should be largely employed in classes that teach Z. To this end, we present an online tutorial especially designed to help students transition from Z to Alloy. The tutorial includes both the classic Birthday Book example and a large real-world scenario based on a Kitchen Environment. Our experiences with novices studying the tutorial suggest that the tutorial helps students learn both Z and Alloy. In addition, novices can answer questions correctly about the approximately 500-line Kitchen Environment model after only a few hours of study.
