Abstract

Many CSCL systems have embraced scripting and service oriented computing to achieve effective collaboration and system flexibility, respectively. While learning standards, such as IMS-LD, can be used for scripting, we have encountered some problems to describe activity types, their collaboration properties and learning tools with this standard. The usability of collaboration scripts is limited, since some important features cannot be described. Furthermore, poor description of tools hinders the search of tools, offered as services, in service oriented CSCL systems. To overcome these difficulties, we propose an ontology that can be used to enrich the description of activities and tools in a script. Besides, the authoring process of a learning design is eased due to enforced restrictions in the ontology as well as the use of off-the-self ontology editors. Furthermore, formal and explicit semantics in a script can be exploited to automate the search of tools. This way, service providers can describe their tools in terms of the ontology, while educators can search for them using domain concepts.
