Abstract
The IMS LD specification is internally complex and has been used in a number of different ways. As a result users who have a basic understanding of the role of the specification in interoperability may nevertheless find it difficult to get an overview of the potential of the specification, or to assess what has been achieved through its use. This chapter seeks to make the task simpler by articulating the modes of use of the specification and analysing the work carried out in each. The IMS LD specification is briefly introduced. Four aspects of the IMS Learning Design specification are identified and described: modeling language, interoperability specification, modeling and methodology, and infrastructure. The different opportunities provided by each mode of use are explored and the achievements of work so far carried out are assessed. A number of valuable contributions are identified, but the practical and widespread use of the specification to exchange learning activities has not so far been achieved. The changing technological and organisational environment in which IMS LD operates is discussed, and its implications are explored. Conclusions are offered which summarise achievements with IMS LD to date, with comments on prospects for the future.
