org.olat.catalog.ui.CatalogController

Description:

The CatalogController is responsible for:

displaying the catalog with its categories and linked resources, starting from the supplied root node
handling the access to the actual category:
- OLATAdmin is/should be the owner of catalog root
- LocalTreeAdmin is administrator of a subtree within the catalog
- Author is responsible for adding his resources to the catalog
- ordinary user browses the catalog for quickly finding his desired resources
The CatalogController accomplish this access rights by modifying the corresponding toolbox entries in the GUI, which grant access to the mentioned actions.
handles the controllers and forms allowing to edit, create the catalog structure
1. change category data (name, description)
2. modify category's localTreeAdmin group
3. contact category's localTreeAdmin group
4. add a new subcategory
5. add a resource link
6. remove a resource link
7. paste structure
The OLATAdmin as superuser can invoke all of the above listed actions.
Whereas the LocalTreeAdmin is restricted to the follwing set: on the LocalTreeAdmin's subtree-root-node only 4,6 are possible. But from the children on he/she can invoke any of 1-6 except 5.
The author is solely able to invoke 5.

The catalog is based upon the idea of having a lot of resources which must somehow be ordered to find them quickly. Frankly speaking the catalog only makes sense if no access restrictions to the linked resources apply. This in mind, it is solely possible to link resources which are accessible for the users of the installation. Date: 2005/10/14 12:35:40
