A couple of years ago, One Laptop Per Child embarked on a mission to "create educational opportunities for the world's poorest children by providing each child with a rugged, low-cost, low-power, connected laptop with content and software designed for collaborative, joyful, self-empowered learning". Today, this vision is achieved through the learning environment "Sugar" and the laptop "XO". This talk will start with an overview of OLPC's mission and the XO before focusing more on Sugar. This environment centered around "activities", a model in between document and application centric interfaces, features an interesting data model and data sharing capabilities. However, most of the data produced on the XO stays on the XO and is not accessible to the other devices. I will describe how Semantic Web technologies can be employed to further share and interconnect the data and give an overview of use-cases being implemented on top of "SemanticXO", the Semantic Web toolkit for Sugar.
