THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
When the type name's nodes are expanded (by clicking on the + sign), the added and modified FSs are revealed as shown in Figure 3.2.b.
We use the (+), (-) 
, 
and (~) signs to represent added FS, deleted FS, and modified FS, respectively. Note that, for the FS Journal, we don't have the case of deleted FSs.
...
Check or uncheck the boxes will control the kinds (added or modified) of FSs to be displayed (see Figure 3.3).
Figure 3.3. Selecting Kinds of FS Changes
Check or uncheck the boxes in the tree will trigger the display of the annotationsin the input document section. Operations on the input document section will behave the same way as viewing the normal XMI CAS as described the CAS Viewer's user guide.
Note that it is possible to have FSs that are not a sub-type of Annotationas shown in Figure 3.3 (the uima.tt.Lemmatype is defined as a sub-type of uima.cas.TOP).
Figure 3.4. Non-Annotation Feature Structures
To view the sequence of changes to a FS, select the FS in the tree. A list of changes (added or modified) by the AEs is displayed in the "Change History of FS value" section as shown in Figure 3.5. The displayed information consists of two parts: the last value of the FS and the sequence of changes. The highlight element in the sequence is the FS selected in the tree.
Figure 3.5. Change History of Selected FS - Shows the history for a particular FS, in which component it was created and which subsequent components it was modified.
3.2 Viewing Changes to Index Repository
The information about the changes to index repository is very similar to the changes to the CAS and it is displayed in the Index Journal tab as shown in Figure 3.6. There are two main differences:
- FS Journal tab may contain FSs that are not in the index repository
- Index Journal has an information about the FSs deleted from the index repository and the delete operation followed by an add operation for the same FS will be combined into a modify operation
Otherwise, the operation of the Index Journal tab is identical to the FS Journal tab.
