Linked Data Wrappers (LDWs) turn Web APIs into RDF end-points, leveraging the Linked Open Data cloud with current data. Unfortunately, LDWs are fragile upon upgrades on the underlying APIs, compromising LDW stability. Hence, for API-based LDWs to become a sustainable foundation for the Web of Data, we should recognize LDW maintenance as a continuou...

Linked-Data Wrappers (LDWs) have been proposed to integrate Open APIs into the linked-data cloud. A main stumbling block is maintenance: LDWs need to be kept in sync with the APIs they wrap. Hence, LDWs are not single-shot efforts, but sustained endeavors that developers might not always afford. As a result, it is not uncommon for third-party LDWs...

One of Web2.0 hallmarks is the empowerment of users in the transit from consumers to producers. So far, the focus has been on content: text, video or pictures on the Web has increasingly a layman’s origin. This paper looks at another Web functionality, cross publishing, whereby items in one website might also impact on sister websites. The Like and...

Increasingly, a user's action in a website might have an impact in other websites. The Like and ShareThis buttons are forerunners of this tendency whereby websites strive to influence and be influenced by the actions of their users in the websphere. The term Web Radar is coined to denote software that serves to impact a website (the host) from what...

Social tagging is one of the hallmarks of Web2.0. The most common role of tags is descriptive. However, tags are being used for other purposes such as to indicate some actions to be conducted on the resource (e.g. 'toread'). This work focuses on 'prescriptive tags' that have associated some implicit behaviour in the user's mind. So far, little supp...

Learning Object Repositories constitute a comprehensive strategy to support ICT use in educa- tional contexts. From this perspective, user participation in repository services is a desirable ob- jective. We propose a contribution model that makes it possible to analyze the openness of these services in a repository. We also make a proposal of six W...

Web service technology has proved its way as a function integration enabler. The next step is to achieve application integration whereby one appli- cation is made available within the context of a consumer application, and this can also include the interface. This is the aim of the WSRP initiative, spon- sored by OASIS. This initiative is standardi...

An experimental method is developed to evaluate the possibility of spontaneous emergence of self-reproducing patterns from a quasi-random configuration. In order to achieve viability to the emerging patterns and to their components a robust transition table is designed. Genetic reproduction is compared with self-inspection based reproduction in ord...

In this work we analyze different existing cellular automata capable of reproducing, and conclude that reproduction in those models is attained as a fixed point of the more general operation of construction, instead of being founded as a higher level specialized mechanism. Thus reproduction becomes a very unstable property and this fact is an obsta...

Resumen: Cuando se plantea la tarea de desarrollar una guía que ayude a alcanzar el máximo aprovechamiento del paradigma de los Objetos de Aprendizaje (Learning Objects, LO), tiende a suponerse que dicha guía debe tratar fundamentalmente los aspectos relacionados con la creación de dichos objetos. Sin embargo, el ciclo de vida de los LO pasa por mu...

Resumen: Este artículo desarrolla varias ideas en torno a la creación de una Guía de Buenas Prácticas (BP) sobre Contenidos Digitales Educativos Reutilizables (CDER), incluyendo una definición operativa de CDER que revisa la literatura académica vigente, una aproximación al ciclo de vida de los contenidos y una definición de BP adecuada para llevar...
