Current Clouds offer is becoming day by day wider providing a vibrant technical environment, where SMEs can create innovative solutions and evolve their services. Cloud promises cheap and flexible services to end-users at a much larger scale than before. However, Cloud business models and technologies are still in their initial hype and characterized by critical early stage issues, which pose specific challenges and require advanced software engineering methods.\nThe main goal of MODAClouds is to provide methods, a decision support system, an open source IDE and run-time environment for the high-level design, early prototyping, semi-automatic code generation, and automatic deployment of applications on multi-Clouds with guaranteed QoS.\nModel-driven development combined with novel model-driven risk analysis and quality prediction will enable developers to specify Cloud-provider independent models enriched with quality parameters, implement these, perform quality prediction, monitor applications at run-time and optimize them based on the feedback, thus filling the gap between design and run-time. Additionally, MODAClouds provides techniques for data mapping and synchronization among multiple Clouds.\nMODAClouds innovations thus are: (i)simplify Cloud provider selection favoring the emergence of European Clouds, (ii) avoid vendor lock-in problems supporting the development of Cloud enabled Future Internet applications, (iii) provide quality assurance during the application life-cycle and support migration from Cloud to Cloud when needed.\nThe research is multi-disciplinary and will be grounded on expertise from several research areas. MODAClouds consortium consists of highly recognized Universities and research institutions that will assure a sound scientific progress, SME partners providing expertise on modelling tools, and large companies that assure industry relevance. The MODAClouds approach and tools will be applied on four industrial cases from different domains.

MOST will improve software engineering by leveraging ontology and reasoning technology. To reach this goal, a seamless integration of ontology technology into model-driven software development (MDSD) will be realized, resulting in ontology-driven software development (ODSD). This concerns the integration of all involved artefacts (ontology and modelling languages, models, tools), as well as the development processes (process and reasoning guidance, traceability of models).\nThe MOST artefact integration technology will allow for managing software development and ontology-based validation and knowledge management in an integrated platform. First, integration will address modelling languages. To be able to query and transform integrated models, a unified view of metamodels must be provided. Second, ontologies and models will be integrated so that ontologies can be used in models, and vice versa. For the first time, MOST will enable integrated model chains, transformations between models either consisting of ontologies or system models. Third, ontology-based queries will be integrated on the level of MDA transformations. Querying will support the developer to fulfil requirements and address modelling decisions. The MOST technology will considerably generalize existing infrastructures, such as the ODM, to address the issues at hand.\nThe MOST ontology-driven, model-aware software process will be guided by process guidance ontologies that formalize the rules, conditions and actions a software engineer has to conduct in specific situations. These ontologies will formalize knowledge about software processes and help their guided execution. To be able to guide software engineers through the development of integrated model chains, traceability information will also be provided for the entire chains. With ODSD, ontology-aware software can be constructed, managed, and maintained, which will be proven by three major industrial case studies.

In the domain of network management and operation support systems (OSS), maintainance of thousands of physical network devices is a complex, error-prone and time-consuming task. Consistent device configuration and error identification among plethora of network device types is impossible without tool support. Domain-specific modelling (DSM) methods promise to deal with system complexity by raising the level of abstraction to models. In this paper, we report about conceptualization of a DSM method for physical devices management, that is implemented based on the ADOxx metamodelling platform. The method introduces a hybrid modelling approach. A dedicated DSML is used to model the structure of physical devices, whereas the ontology language OWL2 is used to specify configuration-related constraints. The work resulted in a novel semantic modelling tool prototype that leverage ontology reasoning technology to enhance the modelling. © 2011 Springer-Verlag.

Traceability is widely recognized as being crucial for various software development-related applications, including maintenance, quality assurance, and change management. However, most existing approaches do not augment traceability relationships with semantics going beyond natural language descriptions, thus limiting the potential for automatizing relevant activities such as consistency checking or change propagation. Based on a case study being concerned with preserving the consistency of business process model refinements, this paper introduces a generic, technology-independent, yet expressive approach for defining semantically rich traceability relationships. The concept is instantiated and implemented on the basis of the ADOxx modeling platform and the GReQL query language. © 2010 IEEE.

Model-driven software development (MDSD) bridges the gap between domain-specific abstractions and general purpose implementation languages and promises enhanced productivity for software engineering. The availability and appropriateness of tool environments supporting the developer is a crucial factor for such productivity promises. The widespread use of MDSD on various domains means a special challenge for the development of MDSD environments. Tool users expect advanced tools customised for the very special domain they are working in. However, tool development and customisation is a complex and expensive task. To address these challenges we propose to apply the principles of software product line engineering (SPLE) for feature-based customisation of MDSD tool environments. This paper is an experience report for the development of a product-line of MDSD tool environments that employ ontology technology to advance MDSD. Finally, we discuss the lessons learned as well as the benefits and challenges observed for feature-based tool customisation. © 2011 IEEE.

When planning to move a legacy style application to the cloud various challenges arise. The potential size and complexity of such a project might especially discourage small or medium companies trying to benefit from the advantages the cloud promises. In addition, the field they have to address is still young and very dynamic and related technologies are rapidly changing. Based on on-going work in the context of the MODAClouds EU project, this paper describes an evolutionary, iterative approach to accomplish the migration of an existing application to a cloud based environment. Model based techniques are used to support the steps of this transition process by providing a baseline for the development of appropriate deployment architectures and the selection of suitable cloud providers. In addition they provide necessary abstractions in order to be less dependent on a specific technology stack or cloud provider. In order to show how we imagine the developed approach to be applied in practice we describe an existing traditional 3-tier application based on the meta-modeling platform ADOxx and how it could be moved to the cloud from the perspective of a medium-sized software manufacturing company.

It has been acknowledged that model-based approaches and domain-specific modeling (DSM) languages, methods and tools are beneficial for the engineering of increasingly complex systems and software. Instead of general-purpose one-size-fits-all modeling languages, DSM methods facilitate model-based analysis and design of complex systems by providing modeling concepts tailored to the specific problem domain. Furthermore, hybrid DSM methods combine single DSM methods into integrated modeling methods, to allow for multi-perspective modeling. Metamodeling platforms provide flexible means for design and implementation of such hybrid modeling methods and appropriate domain-specific modeling tools. In this paper, we report on the conceptualization of a hybrid DSM method in the domain of network physical devices management, and its implementation based on the ADOxx metamodeling platform. The method introduces a hybrid modeling approach. A dedicated DSM language (DSML) is used to model the structure of physical devices and their configurations, whereas the formal language for knowledge representation OWL2 is used to specify configuration-related constraints. The outcome of the work is a hybrid, semantic technology-enabled DSM tool that allows for efficient and consistency-preserving model-based configuration of network equipment.
