Talk:Hylos
From Wikipedia, the free encyclopedia
Um, this is rather an advertising broschure. No one outside of the authors actually uses the system, although I have forced more than one student to deal with it. And the text is in German English. I made a few corrections, but must ask the relevance question.
For example, it was written: "Portable electronic formats and hyperreferences in addition stimulate content exchange and interrelations between authors. Following these changes, a new perspective on content as a net of confined, self-consistent 'knowledge nuggets' has been developed. " but actually, HyLOS does not allow import. It will produce a SCORM, badly, that can be imported elsewhere. This is the theory, not actually to be found in the praxis.
"Manually updated metadata will be reduced to seven attributes by different acquisition techniques. " but the meta data cannot acutally be used yet. Wikipedia is not a catalogue of things to come. I am leaning towards a Request for Deletion....
The entire section "Innovation" is not generally true, but postulated by the authors. I'm saving it here in case anyone wants to fix it:

[edit] Innovations in hylOs
[edit] The concept of multiple, contextsensitive links
Hyperlinks, as we know from the WWW and as they are implemented now, address exactly one target and don't include any semantics. Their loss of context leads us to the Lost in Hyperspace phenomenon. In the field of online learning, however, especially interactive elements take up an outstanding function: A learner should see only links, which satisfy his or her learning context, thus, supporting thelearning process. It is easy to understand, that one word will be linked with different information, e.g., beside a web reference exists a bibliography or glossary entry. Such references guide the learner to different relationships and can be of different help, depending on the learner's knowledge level. A beginner is looking, e.g., for a definition, an advanced learner for additionanl information and an expert for background literature. Links will be associated to certain contexts. It is important that only links will be shown, which are of interest for the learner, such that the learner will not be distracted.
hylOs allows exactly that using standards like XLink: different hyperlink layers may be applied onto the same content, as have been predefined by the teacher or selected by the learner. The link contexts realized in hylOs may be understood as the first available implementation of the ideas in the article The rhetoric of hypermedia: some rules for authors by Landow from 1989. Links are represented within contextual containers with the help of semantic web technologies. Consequently links in hylOs are real, semanticly interpreted data objects.
[edit] Instructional paths
Learning content will be saved in eLOs. A complete learning unit, however, consists mostly of multiple learning objects. The process of forming a didactically structured outline from many single learning components is commonly known as instructional design, the way taken by the learner is called instructional path. For an arbitrary reuse of eLOs it must be ensured that the elearning objects can be loosely added to a net. It is necessary to create an overlay network, which is possible in hylOs with the fully graphical iDesigner.
The hylOs iDesigner is an advanced authoring tool enhancing the process of eLearning course production by providing an additional layer for didactical setup. For this purpose hylOs introduces instructional container objects (ICO), which flexibly combine eLOs and instructional descriptions to courses. ICOs are derived from eLOs retaining the complete LOM metadata set and the nesting facility.
Hence, the hylOs iDesigner bridges the gap between reusability and atomicity of eLearning objects on the one hand and individually and coherently designed courses on the other.
[edit] Arbitrary publication channels
Content saved in the hylOs core system remains independently from its appearance. Content can be arranged and published arbitrarily in specific designed output channels (HTML pages, PDF, etc.). For this purpose there are publication generators, which create dedicated structured XML data. Through this, one and the same content can be associated not only with different layouts, but can also be transferred natively to specific, e.g., mobile end devices.
