Traditional topic panel
Topic panels are used to view topics in Wandora. Traditional topic panel is the default topic panel. It views all information of a single topic. Traditional topic panel's visualization is based on grouped text fields and tables. Next image views an example of the traditional topic panel.
Activating the traditional topic panel
As the traditional topic panel is the default visualization of a topic, Wandora user don't need to perform any explicit actions to open a topic in traditional topic panel. Double clicking a topic creates automatically a traditional topic panel if no topic panel is not open already.
If the user needs to activate the traditional topic panel explicitly, the user can choose menu option View > Add topic panel > Traditional topic panel.
To open selected topic in new traditional topic panel, the user can choose context menu option Open topic in > New Traditional.
To close the traditional topic panel the user can left mouse click the close gadget on the top right corner of the traditional topic panel. The close gadget is marked with an icon that looks like an X.
Alternative way of closing the traditional topic panel is to select menu option View > Close current while the traditional topic panel is active or menu option View > Close > Close Traditional w ... while some other topic panel is active.
Viewing and editing a topic in the traditional topic panel
Traditional topic panel views all elements of a topic on a single page. This single page contains field areas for topic identifiers, base name, variant names, classes, occurrences, associations and instances. Each field area is titled with elements type. For example, all instances of a topic locate in Instances area. If topic has no instances, the area is empty.
Base name, subject locator and variant name fields in the traditional topic panel are directly editable while all others are only selectable. Selectable fields and tables are indirectly editable i.e. the user has to open a special editor to edit the property. For example, to edit an association, the user has to select the association first by left mouse clicking the association row, and then right mouse click the selection, and choose context menu option Modify association.
In general, traditional topic panel views classes, instances and associations using topic tables discussed more detailed in Working with topic tables chapter. Subject identifiers are viewed using a simple URI table while occurrences are string tables.
Read the documentation at Editing topics and associations for more information about editing a topic in traditional topic panel.
Hiding topic properties
Sometimes the user may wish to focus on a certain property of a topic and hide other properties.
The user may hide any field areas in the traditional topic panel. For example, the user may hide occurrences by selecting a menu option View > Options > Configure Traditinal topic panel w ... > View occurrences. The eye icon in front of the menu option indicates the current visibility status of the field area. When the eye is closed, the traditional topic panel hides the area. Selecting the view menu option again toggles the visibility of the area.
Selecting menu option View > Options > Configure Traditinal topic panel w ... > View all sets all field areas visible. Selecting View > Options > Configure Traditinal topic panel w ... > Hide all hides all areas except the basename and the subject locator.
The basename and the subject locator fields are always visible. They can not be hidden.
If user has opened several traditional topic panels, each panel has it's own visibility settings.
Previewing subject locator
Traditional topic panel can view a simple preview for certain subject locator types. At the moment Wandora resolves subject locator's type using URI's file suffix. For example, if the subject locator ends with a file suffix jpg, the URI resolves an JPG image and Wandora views a thumbnail of the image above subject locator field.
Traditional topic panel's simple preview supports file formats and suffixes
- Images: jpg, gif, jpeg, tif, tiff, bmp, png
- Audio: aif, wav, au, mid, rmf
- Documents: pdf
As the thumbnail creation doesn't cover all content types and thumbnail creation requires some extra computing, the thumbnail feature is disabled by default. To enable the thumbnail creation the user can choose menu option View > Options > Configure Traditinal topic panel w ... > View subject locators.
Once the preview of an subject locator is visible, the user can right mouse click the preview and can perform some simple operations for the preview or the subject locator.
