To add a new corpus node to the corpus structure/corpus node, select from the tree menu. Enter a name and a title in the appropriate fields. The information given in the Title field will be displayed when hovering the mouse over the corpus node in the tree view. After clicking the new corpus node will be added to the tree structure, linked to the previously selected node.
The difference between this option and (Section 3.1.8) is that with 'add corpus node' the new corpus node and its metadata description are generated from scratch (the metadata description will be very elemental, consisting of only a name and a title). With 'link corpus node', by contrast, you choose already made and uploaded metadata files for the new corpus node.
