Prev	2.3. The Metadata Descriptions Tree panel	Next

Whenever the IMDI Browser window opens up, the node IMDI Corpora is displayed in the Metadata Descriptions Tree panel.

If you want to access any other predefined part of the corpus, do the following:

Go to the Bookmarks panel (see Section 2.2).
Double-click on one of the bookmarks. The corresponding node is displayed in the Metadata Descriptions Tree panel.

In the Metadata Descriptions Tree panel, make use of the following options to navigate through the corpus:

Double-click on any node to open it and display the next level in the hierarchy.

Note

The Metadata Descriptions Tree panel distinguishes between open and closed corpus and session nodes. These are represented through the following icons:

icon of an open corpus node
icon of an open session node
icon of a closed corpus/session

Some program commands do not work when a node is closed. If any of the commands do not seem to work, make sure that the node is open.

	Note
	Because of the large amount of data that is loaded, it may take some time until the IMDI Browser responds to your command and opens a node.

Click on any closed node, and then point with the mouse to it to activate the tool-tip that displays brief information about the node.
Click on any open node to select it. It will be highlighted in blue. The information relevant to the selected node is displayed in the Info/Content (see Section 2.4) and Description panels (see Section 2.5).

Right-click on any selected (i.e., highlighted) node to open a pull-down menu that displays the available options. Click on any item in the pull-down menu to select the corresponding option.
