Digital repositories enable the storage, discovery and retrieval of digital and electronic materials and their metadata at a local or distributed level. Metadata or data about the data is the descriptive information related to the learning material that is critical for its location, sharing and reuse. The repositories are systems that manage access to the reusable learning materials and content (Monge, Oveler, & Azpeitia, 2008). The materials offered are licensed to be used free of charge and include lesson plans, textbooks, games, software, learning objects, and other materials to support both teaching and learning. This trend toward open and flexible learning opportunities supports lifelong learning and access to quality educational opportunities across social boundaries.
