When you open a Natural DDM source (.NSD file), the Natural DDM editor appears. The DDM editor is table-based and comparable to the DDM editor in NaturalONE. The underlying text document remains the source of truth. When you make a change in the table, the Natural language server validates it against the Natural DDM model and writes it back to the file.

The table does not show the Natural source header comment section of a DDM source. When you save the source, this section is preserved unchanged.

You can control the behavior of the DDM editor with the Natural preferences. See DDM Editor Preferences.

The editing features for Natural DDMs are described in the topics below.
