IKnowledgeContentClass Interface
The IKnowledgeContentClass interface defines the methods and properties of, and is implemented by, the KnowledgeContentClass object.
The KnowledgeContentClass object provides a mechanism for identifying and defining the intended purpose of documents stored in SharePoint Portal Server. The KnowledgeContentClass object****corresponds to a document profile in the user interface.
Each KnowledgeContentClass object is associated with a list of properties, but also inherits the properties of the KnowledgeContentClass object it extends. The FullPropertyList property on the KnowledgeContentClass object exposes all of the properties that are available on a KnowledgeContentClass object.

Remarks
The KnowledgeContentClass object defines a document through the ContentClassObject property of the KnowledgeDocument object.
Each KnowledgeContentClass object specifies one or more KnowledgePropertyDef objects. Each KnowledgePropertyDef object defines a property, known as metadata, belonging to the content class specified by the ContentClass property of the KnowledgeContentClass object.
To create a functional content class, set the PKMCDO.cdostrURI_PropertyOrder property. This property is not part of the interface itself. To set the property order, use the Property property of the KnowledgeContentClass object and pass the argument ("urn:schemas-microsoft-com:publishing:propertyorder")=Array. The array contains the desired properties.
Always create the content class in the system/schema directory under the workspace.
