A taxon is a collection of things grouped together according to their basic similarities. For example, an educational taxonomy may be defined as University > Faculty > Department > Specialties and so on. Schemas define the structure, content, and semantics of documents, and in this case, XML documents. In the context of iLearn Learning Environment, taxon schemas are classification systems that can be used to categorize resources like learning objects. This enables users to browse for resources in iLearn Learning Repository organized by categories in defined schemas.
Only views in the IEEE LOM family support taxon schemas. The actual taxon schemas available to a user when entering metadata depend on the view selected. When editing a view, you can specify which of the taxon schemas are available in that view.
By changing a view’s available schemas, you specify the classification systems available to a user when using the view to enter metadata for a resource.
