A survey of model driven engineering tools for user interface design

The introduction of new technologies leads to a more and more complex interactive systems design. In order to describe the future interactive system, the human computer interaction (HCI) domain uses specific models and tools. In another way, the Model Driven Engineering (MDE) approach has been proposed in software engineering domain in order to provide techniques and tools for dealing with models in an automated way. MDE approach is based on models, meta-models, models transformation and models weaving and aims to produce productive models, i.e. models concentrated on their generative power. Considering these two domains and the already existing HCI works in MDE, the goal of this paper is to understand actual HCI design needs and to study how MDE tools can support HCI needs. As a first response, it proposes a survey of existing MDE tools in regards to HCI model management.

A method to build information systems engineering process metamodels

Several process metamodels exist. Each of them presents a different viewpoint of the same information systems engineering process. However, there are no existing correspondences between them. We propose a method to build unified, fitted and multi-viewpoint process metamodels for information systems engineering. Our method is based on a process domain metamodel that contains the main concepts of information systems engineering process field. This process domain metamodel helps selecting the needed metamodel concepts for a particular situational context. Our method is also based on patterns to refine the process metamodel. The process metamodel can then be instantiated according to the organisations needs. The resulting method is represented as a pattern system.

A participative end-user method for multi-perspective business process elicitation and improvement

A business process can be characterized by multiple perspectives (intentional, organizational, operational, functional, interactional, informational, etc). Business process modeling must allow different stakeholders to analyze and represent process models according to these different perspectives. This representation is traditionally built using classical data acquisition methods together with a process representation language such as BPMN or UML. These techniques and specialized languages can easily become hard, complex and time consuming. In this paper, we propose ISEA, a participative end-user modeling approach that allows the stakeholders in a business process to collaborate together in a simple way to communicate and improve the business process elicitation in an accurate and understandable manner. Our approach covers the organizational perspective of business processes, exploits the information compiled during the elicitation of the organizational perspective and touches lightly an interactional perspective allowing users to create customized interface sketches to test the user interface navigability and the coherence within the processes. Thus, ISEA can be seen as a participative end-user modeling approach for business process elicitation and improvement.

ISEAsy: A Social Business Process Management Platform

In today’s rapidly changing environment and constant development of new technologies, organizations must be operationally efficient and agile to respond efficiently and evolve their processes to changing requirements.

Component-Based Development: Extension with Business Component reuse

Component-Based Development Methods (CBDM) become largely adopted and used. They replace the traditional methods by the introduction, in their development lifecycle, of two processes: design for reuse and design by reuse. However, these two processes are not clearly established and are combined in the majority of the CBDM. This paper aims to propose an approach to extend a CBDM by the reuse processes, using the Symphony method as a reference. A special interest is given to the reuse of Business Component for which we propose a conceptual model based on the variability concept that we consider a key property in a reuse process.

Une approche générique pour l'adaptation dynamique des IHM au contexte

The contexts of use vary a lot. It becomes fundamental to adapt user interfaces (UI) to the context. In this article, we choose an approach based on models for UI adaptation. Our approach facilitates the adaptation through a generic and flexible specification of the task tree model. This specification takes into account both similarities and existent variations between different users contexts of the same application. Such models are afterwards adjusted by model transformation such as the Model Driven Engineering (MDE [6]), according to the user situation.

Configuring private data management as access restrictions: from design to enforcement

Service-Oriented Computing (SOC) is a major trend in designing and implementing distributed computer-based applications. Dynamic late biding makes SOC a very promising way to realize pervasive computing, which promotes the integration of computerized artifacts into the fabric of our daily lives. However, pervasive computing raises new challenges which SOC has not addressed yet. Pervasive application relies on highly dynamic and heterogeneous entities. They also necessitate an important data collection to compute the context of users and process sensitive data. Such data collection and processing raise well-known concerns about data disclosure and use. They are a brake to the development of widely accepted pervasive applications. SOC already permits to impose constraints on the bindings of services. We propose to add a new range of constraints to allow data privatization, i.e. the restriction of their disclosure. We extend the traditional design and binding phases of a Service-Oriented Architecture with the expression and the enforcement of privatization constraints. We express and enforce these constraints according to a two phases model-driven approach. Our work is validated on real-world services.

Ingénierie des processus : Une approche à base de patrons

An agricultural spreader device for spreading seed and other granular material, the spreader being constituted by modular assemblies which are attachable to a central carrier assembly mountable on an agricultural machine such as a tractor. Each modular assembly includes a cylinder supported by rollers, the amount of material spread being determined by the adjustment of the cylinder speed. The lower opening of a distribution hopper is located in front of the cylinder top.

Enforcing privacy as access control in a pervasive context

Pervasive applications promote a seamless integration of computer artifacts with our daily an business lives. However, they threaten privacy in two ways. Firstly, adaptation to a users context necessitates a large collection of data. Secondly, context should be addressed when granting users access to information. This paper handles privacy management as an access control problem and argues that privacy should be specified from a global point of view. Investigating privacy specification at a high level of abstraction and its implementation leads to the proposition of a generative approach relying on model-driven engineering. This approach distinguishes a design level for privacy from its execution level. The design level provides a specification language for privacy which emphasizes its contextual features. It is implemented at the execution level as a service composition generated through model transformations. This composition gathers heterogenous entities, such as pieces of software code or devices. The approach is validated on the example of a medical workflow.
