3    Changing entity type and sequence

Once you have included an entity in your taxonomy, in the way described above, it is always possible to change the type of the entity.

As noted in the previous section, the type of an entity is determined by the prefix of its name. Each entity type has its own prefix. Upon creation of an entity, the pertaining prefix will be automatically prepended to the value of parameter QEntityName. This parameter is hidden for a user during a modeling session. A Knowledge Engineer can change a prefix of prefix of an entity name manually in the Workbase and thus change the type. However, be aware that changing the prefix will also change the behavior of the Taxonomy tree! So only do this when you are sure about the changes you want to make.

Changing Entity sequence in Taxonomy tree

Once you have included entities in your taxonomy, it is possible to change their sequence. For example if you want to place Data to Excel above entity Data to Word report select Ship configurator. Now the Workbase shows all QEntity objects one level below the entity Ship configurator. Now click on Data to Excel and drag it to the location between Intact stability calculation and Data to Word report.
