As discussed above () in a database oriented DTD there are links with well defined semantics. There are many different semantics so there are many different link types. For example if a function is importing a variable, the related link should not end at a company or at a measurement unit. For manual authoring, there must be means to follow these different link types. An example of a link manager for the MSRSW.DTD is shown in in the figure below (). In the left pane of this dialog, all link types are displayed. The available objects belonging to the selected link type (in this case variable) are shown in the right pane.
Link manager
Figure 7:
Such a link manager is useful for establishing links as well as for navigation in the instance especially for quickly locating, previewing and editing of available objects. This link manager also supports cross instance linking.
