Current technologies aimed at supporting learning goals primarily follow a data and metadata-centric paradigm aimed at providing the learner with appropriate learning content packages containing the learning process description as well as the learning resources. Whereas process metadata is usually based on a specific standard specification? like ADL SCORM or the IMS Learning Design standard ? the used learning data is specific to specific learning contexts. The allocation of learning resources ? data or services - usually is done manually at design-time of a content package. Therefore, a content package cannot consider the actual learning context since this is only known at runtime of a package respectively the learning process. These facts limit the reusability of a specific content package across different standards and contexts. To overcome these issues, this paper describes an innovative semantic web service-based approach aimed at changing this data- and metadata-based paradigm to a context-adaptive service-oriented approach following the idea of a dynamic allocation of data and services at runtime of a specific learning process. This approach enables a dynamic adaptation to specific learner needs and objectives and supports the development of abstract semantic process models which are re-usable across different contexts and metadata standards. To illustrate the application of our approach and to prove its feasibility, a prototypical application based on an initial use case scenario is provided.

New Media Systems is...
Our New Media Systems research theme aims to show how new media devices, standards, architectures and concepts can change the nature of learning.
Our work involves the development of short life-cycle working prototypes of innovative technologies or concepts that we believe will influence the future of open learning within a 3-5 year timescale. Each new media concept is built into a working prototype of how the innovation may change a target community. The working prototypes are all available (in some form) from this website.
Our prototypes themselves are not designed solely for traditional Open Learning, but include a remit to show how that innovation can and will change learning at all levels and in all forms; in education, at work and play.
