The Spreadsheet Viewer
The spreadsheet viewer allows you to edit slot values in the current KB within
the context of a spreadsheet. The columns are the slot names. The rows are the
frame names. The cells in the sheet are filled with the corresponding slot
values from the current KB.
There are three steps to launching the Spreadsheet viewer. The spreadsheet
viewer is lauched by selecting frames you want to examine from the Taxonomy
Viewer. When you choose the "Spreadsheet Viewr" command from under the
Applications Menu, you are then presented with a dialog that allows you to
select which slots to display in the spreadsheet and the order. Frames can be
listed in the spreadsheet in class order or alphabetically. They can also be
displayed as pretty names or frame names. The frames, selected slots and
corresponding slot values are then ported into the spreadsheet.
The Spreadsheet Viewer does not have the full editing capabilities that you
would expect. Being that this is the first release of the Spreadsheet Viewer,
there are a number of limitations that you should be aware of.
- Instances in the Spreadsheet Viewer
Only instances are displayed in the Spreadsheet Viewer. When you select a
class frame from the taxonomy viewer, its instances are displayed in the
spreadsheet. Selected instance frames are themselves displayed.
- Multiple-valued slots
The Spreadsheet viewer also does not address mulitple values. In the case
of multi-valued slots, one arbitrary value is chosen from the list of
values that exist for a given mulitple-valued frame/slot cell in the
spreadsheet. This is an issue which we expect will be better adressed in
- Facets and Annotations
The Spreadsheet Viewer also does not deal with facets and annontations.
- Frames and Slots
The Spreadsheet Viewer allows you to add frames to the KB. But you should
take note that the same is not true with slots. When the data in the
spreadsheet is ported back to GKB Editor, any extra slots in the
spreadsheet will be ignored. Any frames that have not been added to the
spreadsheet explicitly with the menu command will also be ignored. Unpon
exiting the Spreadsheet Viewer, you will be notified of which framed have
been added to the KB, which frames have been modified, and which slots have
NExS spreadsheet is the product used to feature the spreadsheet viewer. You
will have to have this software to use the spreadsheet viewer. For now, all the
original NExS Spreadsheet commands are available to the user, but we are
working to remove those NExS commands that are not relevant in the context of
the GKB Editor. The NExS spreadhseet commands allow you to edit the cells in
the spreadsheet, searches, sorts, graphing, formatting...
The GKB Menu within NExS is also available to you by the NExS spreadsheet.
The existence of this menu is for the specific purpose of the Spreadsheet
Viewer. The commands under this menu provide the interaction between NExS and
the GKB Editor.
