Current directions in educational repositories, Vanasche
The document discusses educational resource repositories and the European Schoolnet's Learning Resource Exchange (LRE). It describes how the LRE originally aimed to create a federated search of repositories but faced challenges. However, it saw unexpected positive outcomes like the adoption of its application profile. The LRE public portal launched in 2008 and provided access to over 130,000 resources. Issues discussed include national vs. European approaches and ensuring quality and relevance of learning objects.
