The learning technology standardization process is one of the key research activities in computer-based education. Institutions like the IEEE, the US Department of Defense and the European Commission have set up committees to deliver recommendations and proposals in this area. The objective is to allow the reuse of learning resources and to offer interoperability among heterogeneous e-learning systems. The first part of this paper is devoted to the presentation of an up-to-date survey on one of the most prolific fields of the learning technology standardization: educational metadata. The second part shows how these data models are applied by actual software systems to facilitate the location of learning resources. Educational brokerage is a promising field that lets learners find those computer-based training resources that best fit their needs. We identify the main actors involved, their roles, and open issues and trends.
