This paper illustrates the work done and the results achieved within the ELeGI project about the orchestration and the delivery of Learning Services lying in the GRID inside an IMS Learning Design (IMS-LD) Unit of Learning and running under an enhanced version of the CopperCore Player. The added value of GRID technologies for the creation and the execution of dynamic learning experiences is evidenced as well as the experimentation performed to overcome the original IMS-LD limitation on running services is presented. The aim of the ELeGI project is to promote and support a learning paradigm centred on the knowledge construction using experiential based and collaborative learning approaches in a contextualised, personalised and ubiquitous way through the definition and implementation of a service oriented Grid based software architecture
