Content Administration 
The content administrator is involved with all tasks that are relevant to content creation and maintenance.
For more detailed information on the pre-configured administration roles, see Pre-configured Roles.
In this guide, the term "content" refers to objects or components on the portal desktop that directly bring information to portal end users.
Portal content consists primarily of iViews. Each iView brings to the portal desktop specified data from an information resource such as a relational database, ERP system, CRM system, enterprise application, collaboration tool, e-mail exchange system, intranet, or the Internet. iViews return up-to-the-minute information each time they are launched.
You can import ready-made iViews into your portal environment from the Portal Content Portfolio on SAP Developer Network, you can create iViews from templates provided with the portal, or you can develop custom-made iViews using the content creation tools in the portal or using other content development kits.
iViews are generally displayed through portal pages. You can import predefined pages or create your own pages. The page definition includes a list of associated iViews and layout specifications. Also available for import from the Portal Content Portfolio on SAP Developer Network are worksets and business packages. Worksets bundle related pages, iViews, and roles, while business packages are generally groups of related worksets.
User access to content is determined by role definitions. A portal role is a collection of task-oriented content. While portal content is developed to enable access to information relevant to the organization in which the portal is deployed, roles define the subset of content available to each functional role within the organization. Users are assigned to the role or roles that provide content relevant to them. A user has access to the content that has been assigned to all of his or her roles.
The role definition determines the navigation structure within the portal. The navigation structure consists of the top-level navigation bar, and the detailed navigation tree. A user navigates portal content by clicking tabs in the top-level navigation and detailed navigation.
