All objects in the DMWB are called entities of a content model. In this documentation, the shorter term entities is also used. An entity is a concrete or abstract object in the content model that is uniquely identifiable and for which various types of information are stored. The status of an entity is either active or inactive. An active entity is converted to the internal format of the Knowledge Provider runtime layer. The total amount of entities as represented in the DMWB in a hiererchical structure is called the entity tree.

In the DMWB, there are three views for representing entities. The sorting criteria for the views are as follows:

• Document areas
• Development packages
• Virtual classes

When you first open the DMWB, the Document areas view opens by default.

Here, you can use the arrow keys to move backwards or forwards through the steps.

To see a context-sensitive menu of the functions available for a particular object, right-click on the object.

There are also three tools available that are independent of the entities and that allow you to switch from the entity view in the right-hand section of the screen to tabulation or connections. You can use these tools for the following entities:

• You can switch from the entity properties view to tabulation for LOIOs, PHIOs, and relationship classes. To do this, choose Tabulation . If you choose Attributes , you are taken back to the entity properties view.
• The same applies when you want to switch from the connections display back to the entity properties view. To switch to the connections display, choose Connections .

To navigate forwards, double-click on the fields in the right-hand part of the screen. The field you click on is displayed as the main entry in its current environment. Again, you can go to another field by double-clicking on that field. Choose the arrow pointing left to return to the previous entry.
