In recent years, research on mash-up technologies for learning environments has gained interest. The overall goal is to enrich or replace traditional learning management systems (LMS) with mash-ups of widgets and services that can be easily combined and configured to fit the learner needs. This paper presents the implemented prototype of the ROLE interoperability framework and a business and an educational case study. The framework provides a common technical infrastructure to assemble widgets and services in Personal Learning Environments (PLEs). Evaluation results indicate that the perceived usefulness and usability is high for one case study in which a mature LMS was enriched with ROLE technology. In the second case study, an early mash-up prototype was deployed. The usefulness and usability of this early prototype were rated low, but the case study provides interesting insights for further research and development.

Within the ROLE research project it has been evaluated how personal learning environments (PLEs) perform in different surrounding conditions. Companies do often lag behind in the state-of-the-art developments from research especially in terms of Technology Enhanced Learning. Festo therefore observed on its internal test bed how PLEs can be implemented in business contexts and how to involve the learners in this process. Since there is already a broad variety of tools to organise and manage formal learning processes within companies the test bed didn't start by scratch either. The focus was thus on how to open up an existing learning management system (LMS) towards a PLE. During this process many experience from both learners as well as administrators, and training organisers have been gathered. One of the lessons learned is that a pure PLE doesn't fit the requirements on personnel development in business context, but certain PLE aspects can improve individual learning processes significantly. One showcase is the Festo LearningTube which was developed during ROLE. This is an example for the successful integration of user generated content into a corporate LMS.

The development of information and communication technologies (ICT) offers a wide range of tools and application options or even completely new forms of learning in this regard.
