Categorizing documents
Categorizing is useful when you want to distinguish related documents in the system based on, for example, their topic. You can create a category hierarchy in which you can map the various topics the documents on your site cover. Categorizing is a different approach to sorting documents in the system from the one described in Tags.
Developers can create pages so that users can then view documents based on the categories they are interested in.
