    Integrating the common variability language with multilanguage annotations for web engineering

    Web applications development involves managing a high diversity of files and resources like code, pages or style sheets, implemented in different languages. To deal with the automatic generation of custom-made configurations of web applications, industry usually adopts annotation-based approaches even though the majority of studies encourage the use of composition-based approaches to implement Software Product Lines. Recent work tries to combine both approaches to get the complementary benefits. However, technological companies are reticent to adopt new development paradigms such as feature-oriented programming or aspect-oriented programming. Moreover, it is extremely difficult, or even impossible, to apply these programming models to web applications, mainly because of their multilingual nature, since their development involves multiple types of source code (Java, Groovy, JavaScript), templates (HTML, Markdown, XML), style sheet files (CSS and its variants, such as SCSS), and other files (JSON, YML, shell scripts). We propose to use the Common Variability Language as a composition-based approach and integrate annotations to manage fine grained variability of a Software Product Line for web applications. In this paper, we (i) show that existing composition and annotation-based approaches, including some well-known combinations, are not appropriate to model and implement the variability of web applications; and (ii) present a combined approach that effectively integrates annotations into a composition-based approach for web applications. We implement our approach and show its applicability with an industrial real-world system.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

    Integrating ontologies into the collaborative authoring of learning objects

    Get PDF
    Authoring learning material is a multi-disciplinary undertaking where different people can play their role. Any support that can be provided for the collaboration of instructional designers, pedagogues, media designers, and students, among others, is welcome. In particular, metadata annotation of learning objects is an important task within the whole authoring process. This work presents the first resulting products and approaches from the MD2 project, consisting of a service-oriented framework and a tool to support the integrated, ontology-based collaborative annotation of learning objects

    Orchestration of e-learning services for automatic evaluation of programming exercises

    Managing programming exercises require several heterogeneous systems such as evaluation engines, learning objects repositories and exercise resolution environments. The coordination of networks of such disparate systems is rather complex. These tools would be too specific to incorporate in an e-Learning platform. Even if they could be provided as pluggable components, the burden of maintaining them would be prohibitive to institutions with few courses in those domains. This work presents a standard based approach for the coordination of a network of e-Learning systems participating on the automatic evaluation of programming exercises. The proposed approach uses a pivot component to orchestrate the interaction among all the systems using communication standards. This approach was validated through its effective use on classroom and we present some preliminary results

    Development of Web Based Application for Supply Chain Management

    As a firm staying competitive in the market is never easy. It faces a lot competition from each and every competitor. The firms have to always come up with a better strategy to satisfy their customers, incorporate latest technologies to provide better service to their customers. The web based application for the supply chain management is a solution that supports collaboration in Supply Chain as the foundation for gaining competitive advantage and maintain market share. There are some other ways to obtain the collaboration but this is a better solution. There are several technologies that are needed for the design and implementation of this web application, some of the include technologies like Java, HTML, CSS, Java Script, Angular JS, Angular Schema form. There is a high level integration needed to bring this on to a single track and make this work. This web application has used the up to date technologies so this way the application can be the most sophisticated one on the market. This application uses technologies that are completely open source and involves a lot less capital than other tools out there in the world. This way the firm whoever uses this technology will be able to see a growth in the productivity, higher profits and the most important thing would be to make the customers happier. With some minor changes to the application it shall be able to make it available to other companies as well. This report describes the technologies used and how are they integrated, if this application was really able to manage the supply chain management in the company. This section gives an overview about the design of the application, the forecasting of the demand. The results showed an improvement in the manufacturing process of the company, reduction in the transportation costs

    Proceedings of the 3rd Workshop on Domain-Specific Language Design and Implementation (DSLDI 2015)

    The goal of the DSLDI workshop is to bring together researchers and practitioners interested in sharing ideas on how DSLs should be designed, implemented, supported by tools, and applied in realistic application contexts. We are both interested in discovering how already known domains such as graph processing or machine learning can be best supported by DSLs, but also in exploring new domains that could be targeted by DSLs. More generally, we are interested in building a community that can drive forward the development of modern DSLs. These informal post-proceedings contain the submitted talk abstracts to the 3rd DSLDI workshop (DSLDI'15), and a summary of the panel discussion on Language Composition
