The Application can be queried by Guests and Users for Component of interest to them. Queries are defined with respect to the metadata schemas defined for each type of Component. The metadata schemas conforms with existing metadata sets, such as IMS Content Packaging (IMSCP) and Dublin Core (DC).

The benefit of having such an Application is that the intelectual provider, who has a semantic knowledge about the working material, also provides relevant metadata. Also, the working material can be organized in different hierarchies, each describing different tracks in the material. Using existing metadata sets ensures compabillity with other similar systems.
