ABSTRACT
Open Learning Repositories (OLRs) are metadata-based course portals that structure and connect modularized course materials distributed all over the Web. The modular content is integrated by explicit metadata information in order to build courses and connected sets of learning materials. Modular content can be reused for other courses and in other contexts, leading to a course portal, which integrates LOs from different sources and authors. The system houses a relational database to store all metadata. The database does not store content, but references it by Uniform Resource Locator (URLs). The OLR system at the time of writing houses two courses, one in Artificial Intelligence and one in Software Engineering.
