Property filter |
Selects the properties that are to be rendered on the screen, for example, in a navigation iView. |

Namespace filter |
Affects namespace operations like retrieving and displaying resources for a RID. For example, in an authoring environment, a filter can map a different resource to a RID, depending on the user involved. When the author wants to view the document, the current raw version of the resource is displayed. When others want to see the document, the last published version is displayed. |
