An Infrastructure for Intercommunication between Widgets in Personal Learning Environments

Widget based mashups seem to be a proper approach to realise self-organisable Personal Learning Environments. In comparison to integrated and monolithic pieces of software developed for supporting certain workflows, widgets provide small sets of functionality. The results of one widget can hardly be used in other widgets for further processing. In order to overcome this gap and to provide an environment allowing easily developing PLEs with complex functionality, the based on the TenCompetence Widget Server [1], we developed a server that allows widgets to exchange data. This key functionality allows developers to create synergetic effects with other widgets without increasing the effort of developing widgets nor having to deal with web services or similar techniques. Looking for available data and events of other widgets, developing the own widget and uploading it to the server is an easy way publishing new widgets. With this approach, the knowledge worker is enabled to create a PLE with more sophisticated functionality by choosing the combination of widgets needed for the current task. This paper describes the Widget Server developed within the EU funded IP project Mature, which possibilities it provides and which consequences follow for widget developer.
