Once you have created and linked external (shared) metadata, in case you want to put them into the graph, you need to convert them to internal metadata. In such a case you would see their structure in the graph itself.
You can internalize any linked external (shared) metadata file by right-clicking the linked external (shared) metadata item in the Outline pane and clicking from the context menu.
You can even internalize multiple linked external (shared) metadata files at once. To do this, select the desired external (shared) metadata items in the Outline pane. You can select adjacent items when you press Shift and move the Down Cursor or the Up Cursor key. If you want to select non-adjacent items, use Ctrl+ at each of the desired items instead.
After that, the selected linked external (shared) metadata items disappear from the Outline pane Metadata group, but, at the same location, newly created internal metadata items appear.
The original external (shared) metadata files still
exist in the meta
subfolder and can
be seen in the Navigator pane.
