Publishing Center uses a standard hierarchical structure to organize and display content. The hierarchical structure organizes and displays content as a content tree.

The Publishing Center content tree organizes content according to a hierarchy that includes, at its top, content types, followed by content categories, content subcategories, and, at its bottom, content items. Content types correspond to the content tree's main branches. Content categories branch from content types. Content subcategories branch from content categories. Finally, content items correspond to leaves of the content tree.

Use the Publishing Center content tree to access and use, as well as to create, modify, manage, maintain, and store content types, categories, subcategories, and items that appear on your One-To-One site. The One-To-One database stores the content tree, including the content types, categories, subcategories, and items that comprise the tree.

Information about how Publishing Center organizes content types, categories, subcategories, and items, and displays them for use, appears in the chapter subsections that follow immediately, and appear listed here:

• "About sample content types".

• "Content is organized and displayed in a content tree".

• "Navigating a content tree".

• "Parent and child relationships in the content tree".

• "Subtypes are subsets of content types".

• "The category Unclassified".

About sample content types

The BroadVision application Publishing Center provides sample content types. The sample content types include content categories, subcategories, and content items.

Sample content types are installed during installation of Publishing Center. Names of sample content types, together with descriptions, appear listed here.

Immediately after installation and implementation of Publishing Center, your Publishing Center site will include only one set of content types: BroadVision sample content types.

Developers and administrators may implement new content types by two means:

• customizing BroadVision sample content types

• creating new content types.

To customize sample content types, or create new content types, developers and administrators use the Publishing Center option full form, and the screens and capabilities the option provides.

Content categories and content subcategories are implemented during application setup. During application setup, your site's managers use the BroadVision application BroadVision Command Center to create content categories and subcategories.
