1    Adding parameters to Hydrostatics Image Removed

• Create a new class alongside Dimensions and call it General.
• Create the following parameters (all are values) within the Knowledge Browser:

...

To connect the relation, in the Workbase, select the parameter Displacement in entity Hydrostatics. Then, select the right mouse button menu Taxonomy>Choose/create relation or relation or press Ctrl+T. A window will open showing the available relations for the selected parameter in the Knowledge Browser.

You can browse through the available relations and select the relation you want to use to compute the parameter, see Figure 67below. In this case select the relation you have just created. The same method can be used to include any available relation for any selected parameter.

1. The general approach is to create entity relations in the taxonomy.
2. The main reason to use normal (global) relations and connecting them to parameters in an entity is when you know that the relation will be used at more than one spot in the taxonomy. In that case you rather create one relation and connect it to the parameters in the relevant entities.
3. Also , use normal relations if you want to use the modeling/reasoning functionality of Quaestor. You might want to use the modeler when you want to execute complex models which make use of reasoning an advantage over a normal traditional fully hardcoded model (which a taxonomy is to some extent). This is the case when you want the structure (network of relations) of a model to be dependent on the choices made and input provided by the user. You then have a hybrid knowledge base (mix of taxonomy and classical).
