hylOs Concepts and Ideas
The Hypermedia Learning Object System (hylOs) has been designed to provide full educational content management based on the eLO information model. All knowledge bricks are composed of rich media content elements decorated with a complete set of IEEE LOM metadata and interconnected by qualified relational pointers. They reside within the Media Information Repository (MIR). The rigorous use of the XML technology framework ensures a consistent separation of content, structural information, application logic and design elements. hylOs provides adaptive eLearning functions and may attain any look & feel by applying appropriate XSL transforms.
hylOs offers variable content access views to the learner. Besides the primary content tree elaborated by the author(s), instructional design hierarchies may be compiled from repository objects for each teaching trail. Based on its qualified relations, the content additionally is organised in a semantic net, suitable for individual exploration in a constructivist fashion. Traditional hyperreferences, which provide a separate layer of content traversal, may be customized within hylOs, as well. By means of the MIR Adaptive Context Linking Environment (MIRaCLE), different hyperlink layers may be applied on the same content, as have been predefined by the teacher or selected by the learner. Links are represented within contextual containers, each one suitable to express a narrative of a specific hyperlinking scheme. Note that textually coherent hyperlink collections provide an additional, meaningful structure to be harvested in future applications.
