Targeting users with personalized content is an important part of Interaction Management. You can use Placeholders and Campaigns to control the type of content you display and how long the content appears. The first step is to add content types and content to your BEA Repository.
This chapter includes the following sections:
Use the Content Management Guide to learn how to add content to your BEA Repository. You can set up a hierarchy of folders and add content types (each of which contain properties). Content types determine the metadata you associate with a content file and how the content is retrieved in a search.
You can create your own custom content types, or use the following six content types that ship with WebLogic Portal:
Plan your content types carefully. You can add a property definition to the content type after you have instances of the type. However, you cannot modify or delete existing property definitions of the type. Content type properties describe the content and help you manage that content. The more properties you associate with content items, the more granular your search results can be.
Adding specific properties to content items in your repository can make an image clickable, end a Campaign after a specific number of clicks, start a movie, provide a clickable URL, and so on. You can also perform repository management with content properties by viewing the date (a Content Type property) that the item was added to the repository.
Content type properties can be any of the following data types: Boolean, Long Integer, Number with a Decimal, String, Date/Time, Binary, Nested Content Type, or Link. See the Content Management Guide for more information.
| Tip: | You should set up your content type properties before you create Placeholders and Campaigns that access this content. |
If you create Visitor Entitlements on a Content Management resource, these entitlements can prevent a portal visitor from seeing content they would normally see according to Personalization rules.
A Placeholder—the JSP tag in a JSP that displays general content or personalized content for a Campaign—displays one piece of content at a time. When a content query in a Placeholder (a default Placeholder query or a query put in the Placeholder by a Campaign) returns multiple possible content items to a Placeholder, the Placeholder determines which content item to display. Use a content type property called adWeight to change the chance of displaying content in a Placeholder when the content items are retrieved with a query.
The adWeight property is an Integer property type. The higher the adWeight number you assign to a content item, the better the chance it will display in the Placeholder. See Creating a Placeholder for instructions on using the adWeight property.
