The web client does an adaptation of the container/object server-side data model to the more user-friendly folder/file data model. The client uses the API to retrieve info about the containers and objects from the server and displays them in a tree-like structure. It uses two special gwt widgets, CellTree (https://developers.google.com/web-toolkit/doc/latest/DevGuideUiCellWidgets#celltree) and CellTable (https://developers.google.com/web-toolkit/doc/latest/DevGuideUiCellTable) for the folder tree and filelist accordingly. The CellTree widget initiates calls to the API at the beginning and each time a subtree is expanded in order to fetch all info needed to display the subfolders. That way the datamodel is controlled by the widget.
