Property Filters
You use property filters to manipulate properties of documents and folders and to control which properties are visible to users. For example, you can write a property filter that changes a document property that in turn triggers a workflow.
Some property filters are contained in the standard delivery of KM. They are used by repository services such as the rating service and time-dependent publishing service to display service-related data in the properties dialog box for documents.
If a property filter computes and stores application properties of resources, the application property service must be activated for the repositories containing these resources.
Property filters can be implemented as read filters or write filters.
The following table lists the parameters of property filters that can be specified during the configuration. Some parameters are not relevant for some filters.
