 Chapter IV Opportunities, Achievements, and Prospects for Use of IMS LD David Griffths The University of Bolton, UK Oleg Liber The University of Bolton, UK Copyright © 2009, IGI Global, distributing in print or electronic forms without written permission of IGI Global is prohibited. AbstrAct The IMS LD specifcation 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 specifcation in interoperability may nevertheless fnd it diffcult to get an overview of the potential of the specifcation, 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 specifcation and analysing the work carried out in each. The IMS LD specifcation is briefy introduced. Four aspects of the IMS Learning Design specifcation are identifed and described: modeling language, interoperability specifcation, 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 identifed, but the practical and widespread use of the specifcation 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.
