With the increasing adoption of the web-services stack of standards, service-oriented architecture has attracted substantial interest from the research community which has produced several languages and methods for describing and reasoning about services. These languages cover many concepts ranging from individual services and their code generation from specifications, service semantics, service compositions and networks, economics and business aspects around service ecosystems etc. However, this abundance of specification languages has also resulted in communication difficulties between stakeholders and hinders tasks such as service composition, discovery and maintenance. The presented work is a step towards the unification of the specifications and different aspects of service systems using Model-Driven Engineering. We propose a generic and abstract web service meta-model called WSMeta, which has the ability to describe both operation-centric web services (WS-*) and datacentric web services (REST) and can be used in tasks such as service evolution analysis and service systems maintenance.

Resumen-En la actualidad, el uso de tecnologías educativas para dar soporte al aprendizaje y la gestión del conocimiento tiende a la personalización y la adaptabilidad. Los ecosistemas de aprendizaje se posicionan como una solución tecnológica capaz de proporcionar entornos de aprendizaje que evolucionen con el tiempo a medida que cambien las necesidades de sus usuarios o surjan nuevas herramientas para la gestión del conocimiento. El ecosistema deberá ser capaz de soportar el incremento de la complejidad interna para ofrecer de forma transparente más funcionalidad y sencillez a los usuarios. Además, en un ecosistema tecnológico, los componentes software son heterogéneos, de tal forma que pueden estar desarrollados en diferentes lenguajes y tener requisitos diferentes para su correcto funcionamiento. En este contexto, uno de los principales objetivos a la hora de definir y desarrollar ecosistemas de aprendizaje es establecer las bases para que dichos procesos sean independientes de plataforma. Este trabajo plantea el modelado de un ecosistema de aprendizaje para la gestión del conocimiento en programas de doctorado siguiendo el marco de trabajo Model-Driven Architecture definido por el Object Management Group.Palabras clave: ecosistema de aprendizaje; MDA; modelado; gestión de la información; ingeniería del software Abstract-Nowadays, the use of educational technologies to support learning and knowledge management tends to personalization and adaptability. Learning ecosystems are positioned as a technological solution capable of providing learning environments that evolve over time as users' needs change or new tools for knowledge management emerge. The ecosystem should be able to support transparently the increase of internal complexity in order to offer more functionality and simplicity to users. In addition, in a technological ecosystem, the software components are heterogeneous, in such a way they can be developed in different programming languages and have different requirements for correct operation. In this context, one of the main objectives to define and develop learning ecosystems is to establish the basis for these processes are platform independent. This work proposes the modeling of a learning ecosystem for knowledge management in PhD programs following the Model-Driven Architecture framework defined by the Object Management Group.Keywords: mínimo learning ecosystem; MDA; modeling; information management; software engineering INTRODUCCIÓNLos ecosistemas tecnológicos son un marco general que permite definir y desarrollar cualquier tipo de solución tecnológica en la que los datos y la información son el centro del problema.La metáfora de ecosistema tecnológico proviene del mundo de la biología y en los últimos años se ha transferido a otros ámbitos para representar mejor la componente evolutiva de las relaciones que tienen lugar en contextos sociales, económicos, etc. Existe un gran número de definiciones de ecosistema natural, pero todas hacen referencia a tres elementos principales: los organismos ...

A Service represents an underlying capability offered by a service provider. A service description describes two facets of a service -the service functionality (capability onoffer) and the terms at which the service is offered (terms of offer). The capability onoffer satisfies the goal of a service consumer under the constraints of the terms of offer. Service Policies are used to define the terms of offer of a service offering. Policies could potentially apply to service-level, domain-level or technical (infrastructural) aspects. In this paper, we present a systematic model-driven development approach to deal with service policies from the perspective of a service provider. Our approach addresses the entire development spectrum of service policies. It addresses definition of service policies using visual models and attaching these policy models to service capability description models. It also addresses transforming these policy models to executable specifications and finally enforcing these policies during service invocation.
