Themes, Navigation and Classification

Eurêka makes extensive use of themes as a simple classification system. They work similarly as an operating system's filesystem. Thus, each theme can contain subthemes and learning objects. Each subtheme can only have one parent. Each learning object must be part of at least one theme, but it can also be linked to multiple themes. Just like a library's reference card could be classified in the authors section, while an identifical copy can be found in the titles section.

Each theme has its own properties, its children will automatically inherit them, they can also override some or all of these attributes :

  • Name
  • Description
  • Access rights
  • Vocabularies

The vocabularies associated with a theme, will become available as vocabularies for the Classification element (LOM 9) of each learning objects of this theme. Moreover, it is then possible to navigate the tree structure based on theses vocabularies as if they were themes. If a thumbnail is linked to a learning object, it will be displayed while using the thematic navigation.

It is also possible to export the most recent learning objects of a themes hierarchy, or any vocabulary represented as a theme, as an RSS v2.0.

Linking thumbnails to learning objects

Eurêka allows an optional thumbnails to be set for each learning object. They will appear while navigating through themes. In order to associate thumbnails to some learning objects, you must create dictionnary-type VDEX vocabulary whose id contains the string «thumbnails». Add a MediaDescriptor? (VDEX 6.5.1) element containing a valid URL pointing to a JPEG or PNG picture. Finally, in the learning object, add a taxon path (LOM 9.2) pointing to the appropriate vocabulary term in the special «thumbnails» vocabulary.
