The Knowledge Directory is similar to a file system tree in that documents are organized in folders and subfolders. A folder can contain documents uploaded by users or imported by content crawlers, as well as links to people, portlets, and communities. If your administrator has given you permission, you might also be allowed to add documents to the Knowledge Directory, or submit yourself as an expert on a particular topic.
The default portal installation includes a Knowledge Directory root folder with one subfolder named Unclassified Documents. Before you create additional subfolders, define a taxonomy, as described in the Deployment Guide for Oracle WebCenter Interaction. For example, you probably want to organize the Knowledge Directory in a way that allows you to easily delegate administrative responsibility for the content and facilitate managed access with access control lists (ACLs).
When you open the Directory, you see the folders and subfolders to which you have at least Read access. After you have opened a Directory folder, you see additional features: documents, document display options, subfolders, and related objects.
On the left, you see the documents to which you have at least Read access. Each document includes an icon to signify what type of document it is (for example: web page, PDF, MS Word document), the document name, the document description, when the document was last modified, a link to view additional document properties, and a link that displays the URL to this document (enabling you to e-mail a link to the document). At the bottom of the list of documents, you see page numbers indicating how many pages of documents exist in this folder.
At the top of the list of documents, you see drop-down lists that let you change how documents are sorted, how many documents are displayed per page, and filter what types of documents are displayed.
