The MELOD environment has been designed to support, through the use of mobile devices, the informal learning experiences that take place during the visit of a city,. In the last few years, many applications for mobile devices have been developed with the aim of supporting students during a visit experience. One of the main difficulties in designing and managing these applications is related to the content, since usually it must be prepared in advance by the teachers, and maintained during the lifespan of the application, thus requiring an extra effort to organize the information for mobile devices and also to maintain the content updated. MELOD exploits the huge amount of dataset in the Linked Open Data (LOD) cloud to overcome the previous issues, by providing contextualized updated information based on students' location. The MELOD environment interlinks the DBpedia, Europeana and Geonames datasets with the contextual information of the students' learning experience. Finally, students social activities, like voting and commenting, are also used to feed new knowledge into the MELOD environment.
