IDLD, Implementation and Deployment of Learning Design http://www.idld.org, is a Canadian project that aims to bridge the gap among IMS Learning Design researchers and developers and pedagogical designers. Two main products of the project are a well founded, well supported and well tooled implementation process for describing new or existing IMS-LD compliant units of learning and a repository of reusable Learning Design examples and generic templates. In this paper we describe the proposed implementation process and tools and how it was carried out by four IDLD teams building Units of Learning (UoL) for the repository. In each case, IMSLD compliant Units of Learning were produced from existing scenarios, leading to a set of both generic and exemplary UoLs. The scenarios were carefully chosen to assure some design quality in order to enhance the reusability potential. The paper concludes with some recommendations and next steps.
