This document discusses the challenges of developing adaptable learning objects that can meet the diverse needs of learners. It introduces LOTTI, a learning object authoring tool that uses learning design patterns and an accessibility wizard to help designers create pedagogically rich and accessible learning objects. LOTTI uses standards like IMS ACCMD and IMS Content Packaging. The document also describes the TAS adaptation service, which can retrieve, adapt, and deliver learning objects based on a user's needs and the resource's capabilities. Further work is needed to expand LOTTI and develop a framework for an open-source adaptable personal learning environment.
