Investigación en el diseño y desarrollo para el enriquecimiento de un framework colaborativo web sensible al contexto

En este proyecto se pondrá en obra el estudio-aplicación-desarrollo de los aspectos fundamentales para el enriquecimiento de un framework web colaborativo con propiedades de sensibilidad al contexto (FWCsc). Para tal fín se proyectan las siguientes acciones con el propósito de fomentar un aporte en perspectiva con intereses de la industria local y la comunidad científica. Primero, desarrollando tareas de diseño, testing, documentación de estilos arquitectónicos y especificación de una herramienta colaborativa web, teniendo en cuenta técnicas y metodología de desarrollo actuales. Segundo, implementación, instalación, configuración y soporte de una aplicación utilizando frameworks de desarrollo estándares. Tercero, consolidar ambientes y prácticas para el aprendizaje-ense˜nanza-investigación, colaboración y otros usos (compartir experiencia, vinculación con la comunidad de usuarios con intereses similares, K-12, Higher-Ed, Portfolios), en la construcción de sitios colaborativos para las actividades de integraci´on entre las c´atedras afines de la carrera de Ingeniería en Sistemas Informáticos (UAI).Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI

Higher-order architectural connectors

We develop a notion of higher-order connector towards supporting the systematic construction of architectural connectors for software design. A higher-order connector takes connectors as parameters and allows for services such as security protocols and fault-tolerance mechanisms to be superposed over the interactions that are handled by the connectors passed as actual arguments. The notion is first illustrated over CommUnity, a parallel program design language that we have been using for formalizing aspects of architectural design. A formal, algebraic semantics is then presented which is independent of any Architectural Description Language. Finally, we discuss how our results can impact software design methods and tools

Semantics-directed implementation of method-call interception

We describe a form of method-call interception (MCI) that allows the programmer to superimpose extra functionality onto method calls at run-time. We provide a reference semantics and a reference implementation for corresponding language constructs. The setup applies to class-based, statically typed, compiled languages such as Java. The semantics of MCI is used to direct a language implementation with a number of valuable properties: simplicity of the implementational model and run-time adaptation capabilities and static type safety and separate compilation and reasonable performance. Our implementational development employs sourcecode instrumentation. We start from a naive implementational model, which is subsequently refined to optimise program execution. The implementation is assessed via benchmarks

Feature interaction in composed systems. Proceedings. ECOOP 2001 Workshop #08 in association with the 15th European Conference on Object-Oriented Programming, Budapest, Hungary, June 18-22, 2001

Feature interaction is nothing new and not limited to computer science. The problem of undesirable feature interaction (feature interaction problem) has already been investigated in the telecommunication domain. Our goal is the investigation of feature interaction in componet-based systems beyond telecommunication. This Technical Report embraces all position papers accepted at the ECOOP 2001 workshop no. 08 on "Feature Interaction in Composed Systems". The workshop was held on June 18, 2001 at Budapest, Hungary

Tool support for coordination-based software evolution

In today's global and highly competitive business environments, organisations are replying to the question of whether technology is forming business or vice-versa by integrating their business and IT strategies, thus using technology to do business. As a consequence, there is an increasing pressure for building software systems that are able to cope with new requirements imposed by both technological advances and different business rules. At the same time, it is now widely accepted that, although Object-Oriented techniques have provided useful tools for software construction, their support cannot be extended directly to evolution. Even worse, it is becoming evident that there is a lack of theoretical principles and accompanying practical tools that can effectively support software evolution. In this paper, we describe in detail a development tool that is based on sound mathematical principles and supports an architecture-based approach to evolution centred on the notion of coordination..
