a. Keywords

The Keywords tool allows users to define searchable tags or formal metadata for nodes, links, or slides. Keywords added to nodes can facilitate later review and comparison of data. Coupled with the ability to search, the metadata creates a powerful analysis tool.

Keywords may also be added from an ontology, which will be covered in the ontologies section.

To add a keyword to a node:

1. Click the node. Sizing handles appear around the node.
2. From the menu bar, select Windows > Keywords. The Info window opens.
3. In the Info window, Keywords section, type a keyword into the text field.
   More than one keyword in a field will be treated as a block of text (string).
   Once a keyword is assigned to a node, the keyword indicator displays.
   To add additional keywords to a node:
4. In the Info window, click the Add tool. An additional keyword text field opens.
5. Type the keyword.

To assign formal metadata schema (VUE comes with the Dublin Core metadata schema):

1. Click the node. Sizing handles appear around the node.
2. From the menu bar, select Windows > Keywords. The Info window opens.
3. In the Info window, Keywords section, click the Assign Categories checkbox. The Categories field displays.
   The default metadata schema is Dublin Core.
4. Click the Categories down-arrow and select a category.
5. Type the keyword.

To create your own custom category:

1. Click the Categories down-arrow and select Edit Categories. The Edit Categories window opens.
2. In the Edit Categories window, type the custom category.
3. Click Close. The custom category is added to the categories list.
