Abstract
Several relevant issues surround the adoption of Linked Open Data for advertising Learning Opportunities: to select a learning opportunity more appropriate to a specific learning context according multiple criteria (e.g. educational, organizational and financial); to choose an adequate modeling language to represent learning opportunities fostering interoperability; to identify similar learning opportunities in order to avoid redundancy or benefit from reuse. This paper has two aims. First, it aims at introducing a survey of the most significant work in the field. Second, it proposes a general model illustrating the key concepts surrounding the learning opportunity concept and highlighting their relationships.
