    Metamodel for Tracing Concerns across the Life Cycle

    Get PDF
    Several aspect-oriented approaches have been proposed to specify aspects at different phases in the software life cycle. Aspects can appear within a phase, be refined or mapped to other aspects in later phases, or even disappear.\ud Tracing aspects is necessary to support understandability and maintainability of software systems. Although several approaches have been introduced to address traceability of aspects, two important limitations can be observed. First, tracing is not yet tackled for the entire life cycle. Second, the traceability model that is applied usually refers to elements of specific aspect languages, thereby limiting the reusability of the adopted traceability model.We propose the concern traceability metamodel (CTM) that enables traceability of concerns throughout the life cycle, and which is independent from the aspect languages that are used. CTM can be enhanced to provide additional properties for tracing, and be instantiated to define\ud customized traceability models with respect to the required aspect languages. We have implemented CTM in the tool M-Trace, that uses XML-based representations of the models and XQuery queries to represent tracing information. CTM and M-Trace are illustrated for a Concurrent Versioning System to trace aspects from the requirements level to architecture design level and the implementation

    Ontological Engineering: What are Ontologies and How Can We Build Them?

    Get PDF
    Ontologies are formal, explicit specifications of shared conceptualizations. There is much literature on what they are, how they can be engineered and where they can be used inside applications. All these literature can be grouped under the term “Ontological Engineering,” which is defined as the set of activities that concern the ontology development process, the ontology lifecycle, the principles, methods and methodologies for building ontologies, and the tool suites and languages that support them. In this chapter we provide an overview of Ontological Engineering, describing the current trends, issues and problem

    A Survey of the State of Dataspaces

    Published in International Journal of Computer and Information Technology.This paper presents a survey of the state of dataspaces. With dataspaces becoming the modern technique of systems integration, the achievement of complete dataspace development is a critical issue. This has led to the design and implementation of dataspace systems using various approaches. Dataspaces are data integration approaches that target for data coexistence in the spatial domain. Unlike traditional data integration techniques, they do not require up front semantic integration of data. In this paper, we outline and compare the properties and implementations of dataspaces including the approaches of optimizing dataspace development. We finally present actual dataspace development recommendations to provide a global overview of this significant research topic.This paper presents a survey of the state of dataspaces .

    Dynamic installation and automatic update of Bluetooth low energy devices in PalCom

    Chronic kidney disease is becoming an increasingly common illness.The medical background for this thesis comes from the prediction that frequent monitoring of body parameters may help prevent progression of the disease. For other chronic diseases other parameters are interesting to monitor and the need is typically dynamic. This thesis presents a solution for dynamic installation of Bluetooth low energy-enabled health care devices and automatic update of such services in the PalCom middleware. PalCom is aspiring to be a helpful tool in the pursuit of improving the quality of health care and provides functionality for taking measurements at home for remote monitoring. However, as most similar systems, PalCom only allows deployment of predefined BLE devices. The contribution of this work is a solution to install BLE-enabled health care devices in PalCom on demand, as well as a solution for automatic update of these services

    [ES] La interoperabilidad semántica de la información sanitaria es un requisito imprescindible para la sostenibilidad de la atención sanitaria, y es fundamental para afrontar los nuevos retos sanitarios de un mundo globalizado. Esta tesis aporta nuevas metodologías para abordar algunos de los aspectos fundamentales de la interoperabilidad semántica, específicamente aquellos relacionados con la definición y gobernanza de modelos de información clínica expresados en forma de arquetipo. Las aportaciones de la tesis son: - Estudio de las metodologías de modelado existentes de componentes de interoperabilidad semántica que influirán en la definición de una metodología de modelado de arquetipos. - Análisis comparativo de los sistemas e iniciativas existentes para la gobernanza de modelos de información clínica. - Una propuesta de Metodología de Modelado de Arquetipos unificada que formalice las fases de desarrollo del arquetipo, los participantes requeridos y las buenas prácticas a seguir. - Identificación y definición de principios y características de gobernanza de arquetipos. - Diseño y desarrollo de herramientas que brinden soporte al modelado y la gobernanza de arquetipos. Las aportaciones de esta tesis se han puesto en práctica en múltiples proyectos y experiencias de desarrollo. Estas experiencias varían desde un proyecto local dentro de una sola organización que requirió la reutilización de datos clínicos basados en principios de interoperabilidad semántica, hasta el desarrollo de proyectos de historia clínica electrónica de alcance nacional.[CA] La interoperabilitat semàntica de la informació sanitària és un requisit imprescindible per a la sostenibilitat de l'atenció sanitària, i és fonamental per a afrontar els nous reptes sanitaris d'un món globalitzat.
