The Systematic Discovery of Services in Early Stages of Agile Developments: A Systematic Literature Review

In recent years, agile methodologies have been consolidated and extended in organizations that develop software in Web environments. For this reason, the development methodology of these organizations will not only be related to Services, but also to the Web Engineering paradigm. These organizations are heading for incorporating software development methodologies whose paradigm can allow integration, naturally and in the earlier stages of Web applications develop with the services of the organization that described and published in the Services Portfolio. The aim of this study will be to analyze the current state of the art in the process of discovering services in early stages of agile software development with focus on those identified requirements that could be covered with the services included in the Service Portfolio. We have identified 20 relevant papers through conducting a double systematic literature review (SLR). It is concluded that no study has been found that can solve the entire process of discovering candidate services within an organization that cover the requirements of a new application developed with agile methodologies. At the same time, guidelines have been found to formalize the solution to this problem and fill in that gap of knowledge by proposing in a single process, the formalization of a requirement based on agile techniques, which can be managed against a Services PortfolioMinisterio de Economía y Competitividad TIN2016-76956-C3-2-R (POLOLAS

Using Attribute-Oriented Programming to Leverage Fractal-Based Developments

International audienceThis paper presents the Fraclet annotation framework. The goal of Fraclet is to leverage Component-Based Software Engineering based on the Fractal component model using Attribute-Oriented Programming. We show that, using Fraclet, about 50% of the handwritten program code can be saved without loosing the semantics of the application, while the rest of the program code is automatically generated

Design process enabling adaptation in pervasive heterogeneous contexts

International audienceIn the next decades, the growth in population ageing will cause important problems to most industrialized countries. To tackle this issue, Ambient Assistive Living (AAL) systems can reinforce the well-being of elderly people, by providing emergency, autonomy enhancement, and comfort services. These services will postpone the need of a medicalized environment, and will allow the elderly to stay longer at home. However, each elderly has specific needs and a deployment environment of such services is likely unique. Furthermore, the needs evolve over time, and so does the deployment environment of the system. In this paper, we propose the use of a model-based development method, the adaptive medium approach, to enable dynamic adaptation of AAL systems. We also propose improvements to make it more suited to the AAL domain, such as considering heterogeneity and a composition model. The paper includes an evaluation of the prototype implementing the approach, and a comparison with related work

Configurable Software Performance Completions through Higher-Order Model Transformations

Chillies is a novel approach for variable model transformations closing the gap between abstract architecture models, used for performance prediction, and required low-level details. We enable variability of transformations using chain of generators based on the Higher-Order Transformation (HOT). HOTs target different goals, such as template instantiation or transformation composition. In addition, we discuss state-dependent behavior in prediction models and quality of model transformations

E‐Service Composition Ontology

Recently, the concept of life event was coined in the literature to describe an event in a citizen’s life that would require at least one or in some cases a collection of public services from e‐government service composition prospective. A system to provide the required intelligence that would be able to compose the basic e‐services to build a composite service has recently become an area of debate with many solutions being proposed. This study building on prior publications is attempting to introduce and provide new technical guidelines for a new ontology that extends Ontology Web Language for Services (OWL‐S) as knowledgebase and intelligent actor for creating composite services to build a life event. This chapter proposes the life‐event ontology that is a logical extension of OWL‐S for implementation of e‐service integration modelling framework proposed in prior publications
