Realize that the following information is a generic description of the user interface. Specific content of a knowledge based system will determine on the determine the specific information it presents. To make a separation between the responsibilities of Quaestor and the developer of the knowledge based system, the Knowledge engineer, think about the following:
...
The standard Quaestor GUI layout can be rearranged at any time by selecting the menu options: Window>StandardView>Window configurations. As with the start-up of Quaestor, in general there are two standard views:
For an End-User, a Domain Expert and a Knowledge Engineer in a project file, Window>Standard View>Window configurations>User will result in:

...
Window>Standard View>Window configurations>Knowledge engineer as an a knowledge engineer in a knowledge base will result in:
...
As a Knowledge Engineer you will have two more windows in addition to the Explanation windowExplanation window and the Workbase: Knowledge Browser and Slots & Properties.
The Knowledge Browser is your main access to the knowledge (such as parameters, relations, constraints) in the system (stored in frames).
The Slots & Properties window provides access to specific properties for the knowledge (or frames = parameters, relations, constraints) you are able to select in the Knowledge Browser.
Instead of the Explanation windowExplanation window, which is only for presentation, you also have the Frame Viewer. This Frame Viewer enables you to modify the reference and data slot information for a frame and the dimension of parameter frames. To get the Frame Viewer instead of the Explanation windowExplanation window, select "Use classic frame viewer" in the "Appearance" tab of the Options windows (Tools>Options...).
...
Every process (calculation, task, whatever) starts with the Process Manager. At the start of a project, this window is automatically initiated, you can also activate this window using theProcess Manager button (when the classic Workbase buttons are used, push or the S button on the right side of the recorder buttons. We advise to use the new Workbase buttons ). Depending on the specific knowledge base, the process manager enables you to:
...
What follows is a process of providing input and making choices. Every time you provide input or make choices you confirm these by pressing the "Accept input & Continue" button (or the play button, depending on your personal settings, see Workbase buttons ).
Choices and input
You give input and choices in the Workbase, the right part of the interface. And while doing so, you are provided with additional information on selected parameters or values in the Explanation window the Explanation window on the left side. The Explanation window will always follow your selection in the Workbase (either a tree item, something in the list or something in the table of the Workbase ). Furthermore, note that Quaestor also provides feedback by means of colors and font styles.
Using the Workbase buttons in the Workbase, you can start or restart a process, accept choices and input and interrupt or stop a process.
By providing answers and choices to questions in the Workbase and using the Workbase buttons to continue, you will be guided through an analysis, design or engineering process. If the correct input is provided and choices are made, you will end up with a result. Quaestor will Quaestor will inform you if this was not possible.
...
When a result is achieved. You can go through all input, intermediate and end results in the Workbase by selecting values and (in case of documents) double clicking values. Note that associated programs will start and load the associated files when you double click them. A Back to Quaestor window will appear on top of the started program in order to return to Quaestor.
Like during the dialog, you will see that the results are presented in all kinds of colors and font styles. These colors and styles have a meaning, go to Quaestor Workbase colors and font styles to read about the details.
...
As a result (and mentioned in the above standard views), the knowledge engineer required additional windows, such as the Knowledge Browser, Slots & Properties and the Frame Viewer to have additional views on the knowledge base.
Browsing knowledge
By means of the Knowledge Browser the KE is able to browse through all parameters, relations and constraints (frames). The Frame Viewer and Slots & Properties will follow the selections in the Knowledge Browser and enable you to modify all kind of aspects on the selected frames. Furthermore, the Knowledge Browser will follow your browsing through the Workbase.
Because all the Childs are interconnected you can easily follow the relation between a result and its origin. For instance, when you select a value of a result in the Workbase, the Frame Viewer tells you which relation requested the value and which relation has determined the value. In addition the parameter is in focus in the left bottom side of the Knowledge browser, and when you select this, it will show all the relations the parameter is part of, and by double clicking which relations can determine the parameter.
Editing knowledge
Editing you use a combination of the Knowledge Browser, Frame Viewer and Slots & Properties.
Note that most of the functionality for the Knowledge Browser is part of the right mouse menu functionality, see also in the following sections.
...
Parameter names can be modified in the Knowledge Browser, simply select the parameter and press F2. The changed name will be propagated through the knowledge base as far a this is recognizable by Quaestor. In other words: Please note that parameters in templates and between quotes are NOT changed! The "Search & Replace..." tool automatically starts as soon you have changed a parameter name. This tool allows you to search and replace the old with the new parameter name also in data and reference texts of all frames in the knowledge base. In particular attention should be paid to modify input templates for satellite programs.
Any additional modifications to reference text or attributes and data in the data slot can be done by means of the Frame Viewer and Slots & Properties. Put the focus on a parameter in thethe Knowledge Browser and make your changes in the Frame Viewer and Slots & Properties.
Adding parameter can be done in two ways:
For Quaestor it is important to know what type of parameter it is adding. You can define this type in two ways:
In other words, when you add parameters by means of a relation, you can also define the type of the parameter.
Note that due to some choices in design, a string parameter in Quaestor cannot in Quaestor cannot be changed to a value type (so removing the $ will not help...). In that case you have to create a new parameter with the correct type.
...
Modification of expressions (relations or constraints) is done by means of the Expression Editor. The window automatically opens when you select an expression and press F2. You can see expressions in the Knowledge Browser by:
When the Expression Editor is opened, it shows the expression in the top part and any additional attributes and data in the bottom part. You can simply modify the expression in the normal way.
The Expression Editor contains syntax information through the Tooltip [2] and a proposing mechanism (a drop down box) for available functions and parameters, based on the parameter type of the left side parameter and any further requirements inside a syntax of a intrinsic function. These two assistants work dynamically while typing your expression. Furthermore, we use syntax coloring for string information (not string parameters), brackets and logical words like AND, THEN, ELSEIF, etc.
New relations can be added using the right mouse menu of the Knowledge Browser. The same Expression Editor is opened and the last parameter or relation that was in focus is included as starting point.
...
Because we want you to think about this, deleting is normally disabled. You can only enable deleting by selecting the File menu item "Allow deleting frames". Every knowledge base is (re-)protected when you (re)start it in Quaestorin Quaestor.
Organise in classes
Beside a description of all your parameters, relations constraints etc. you are able to group relevant parameters and relations in classes in the class tree. You can create a new class and arrange existing classes in the class tree on the left side of the Knowledge Browser and drag and drop parameters and relations in these classes.
The purpose of classes is to organise your parameters. You do this by selecting any existing class and press the right mouse button.
...
To reorder the classes you have to press the button between the forward and back buttons of the knowledge browser (field 2). This button will switch the class tree view between Class List, Domains and Class Tree view (the default view). Please note that button has the name of the view you will switch to (and not the present view). In the Class List mode you will see all classes presented in a syntax showing sub-classes after a dot. So, a sub-class of "Top Goals/Undefined" class is presented as "Top Goals/Undefined.sub-class". You can simply drag and drop the presented class entries in order to manipulate the order of classes and sub-classes. The only class you cannot move is "Top Goals/Undefined".
Please look at the KE Tutorials and Documentation of Knowledge for more details.
Testing knowledge
Every new knowledge component can be tested right away. Simply double click the parameter to be calculated in Knowledge Browser to indicate it is a top goal and press the Create Solution or play button to start your calculation process.
...
The standard windows are activated when a knowledge base is loaded (depending on the standard view above). The standard windows are:
In addition to these windows you have windows that are activated by Quaestor when by Quaestor when you carry out a specific action, such as the Knowledgebase Clipboard, but for instance also the Web browser to provide additional help for intrinsic Quaestor functions. The additional windows are:
Finally you have special modal windows, for instance required to control Quaestor in control Quaestor in combination with other programs. The special modal windows [3] are:
Quaestor has Quaestor has two types of menus:
