    The trend of merging telecommunication infrastructures with traditional Information Technology (IT) infrastructures is ongoing and important for commercial service providers. The driver behind this development is, on one hand, the strong need for enhanced services and on the other hand, the need of telecommunication operators aiming at value-added service provisioning to a wide variety of customers. In the telecommunications sector, the IP Multimedia Subsystem (IMS) is a promising service platform, which may become a ''standard'' for supporting added-value services on top of the next generation network infrastructure. However, since its range of applicability is bound to SIP- enabled services, IMS extensions are being proposed by ''SIPifying'' applications. In parallel to these developments within the traditional IT sector, the notion of Virtual Organizations (VO) enabling collaborative businesses across organizational boundaries is addressed in the framework of Web Services (WS) standards implementing a Service-oriented Architecture (SOA). Here, concepts for controlled resource and service sharing based on WS and Semantic Technologies have been consolidated. Since the telecommunications sector has become, in the meantime ''mobile'', all concepts brought into this infrastructure must cope with the dynamics mobility brings in. Therefore, within the Akogrimo project the VO concept has been extended towards a Mobile Dynamic Virtual Organization (MDVO) concept, additionally considering key requirements of mobile users and resources. Especial attention is given to ensure the duality of the merge of both, SOA and IMS approaches to holistically support SOA-enabled mobile added-value services and their users. This work describes major results of the Akogrimo project, paying special attention to the overall Akogrimo architecture, the prototype implemented, and the key scenario in which the instantiated Akogrimo architecture shows a very clear picture of applicability, use, and an additional functional evaluation

    A Pedagogical Application Framework for Synchronous Collaboration

    Designing successful collaborative learning activities is a new focus of research within the E-Learning community. The social dimension inside the traditional face-to-face collaborative learning is important and must be included in the online learning designs. In this thesis, we introduce the concept of Pedagogical Application Frameworks, and describe Beehive, a pedagogical application framework for synchronous collaborative learning. Beehive guides teachers in reusing online collaborative learning activities based on well-known pedagogical designs, to accomplish their educational objectives within a certain educational setting, and also simplifies the development of new pedagogical collaboration designs. Beehive’s conceptual model has four abstraction layers: Pedagogical Techniques, Collaboration Task patterns, CSCL Components, and CSCL script. By following the framework’s guidelines and specifications, developers will place the control of designing pedagogical collaboration tools in the teacher’s hand rather than in the software designer’s

    Girardin, F., Ayman, M., & Josep, B. (2007). Towards a practitioner-centered approach to the design of e-learning competence editors. In T. Navarrete, J. Blat & R. Koper (Eds.), Proceedings of the 3rd TENComptence Open workshop 'Current Research on IMS Learning Design and Lifelong Competence Development Infrastucture' (pp. 99-104). June, 20-21, 2007, Barcelona, Spain: TENCompetence.This article reports on the background research on requirements and current approaches to editors for learning curriculum designers. First we take a critique look at the state of the art in the domain of learning activity editors. We then look back in the information visualization and interaction literature to discuss the design challenged of such tools. From these current theories and applied works we define a set a rules that are crucial for the design of CDP editors based developed on top of complex e-learning models. Finally, we exemplify the set of design rules with a prototype integrating tightly coupled map-based and Gantt chart views.The work on this publication has been sponsored by the TENCompetence Integrated Project that is funded by the European Commission's 6th Framework Programme, priority IST/Technology Enhanced Learning.

    Experiences with GRAIL::Learning Design support in .LRN

    The IMS-LD specification allow the transcription of almost any pedagogical model in a "Unit of Learning" (UoL), which is a package where contents and methodology are combined together in order to be deployed in a compliant software. Making use of GRAIL as the supporting tool inside the .LRN Learning Management System, this paper presents two real experiences of use where IMS-LD has been used to deploy pedagogical models with different levels of complexity
