A Service Oriented Collaborative Distributed Learning Object Management System

Learning Objects are stored in repositories and spread through Internet. The educational sector needs to share good quality educational contents, which can be reused and adopted in several contexts. In this paper we present a Service Oriented and SCORM conformant system, named CD-LOMAS (Collaborative Distributed Learning Object MAnagement System), supporting the sharing of contents and collaborative teaching in a highly distributed environment. Complex Learning Objects are decomposed into simpler Learning Objects that can be distributed at different sites. The adoption of a service oriented architecture enables to federate distributed Learning Management System at content level. CD-LOMAS has been developed as a MOODLE plug-in and is equipped with an extensible service oriented architecture supporting artifact management features, such as coordination of cooperative teaching and versioning, which are integrated with context-awareness.
