Selected property descriptions

This topic presents information about the following selected Content Engine properties and property-related information.

Date Content Last Accessed and Content Access Recording Level

The Content Access Recording Level property specifies the default value for an object store for how often the Date Content Last Accessed property is recorded. Content Access Recording Level is a settable property of the object store and appears only on the object store property grid in Enterprise Manager. Date Content Last Accessed is a read-only document property and appears only on the document property grid in Enterprise Manager.

To update the Date Content Last Accessed property, select one of the following options:

Date Content Last Accessed is updated when all three following situations are fulfilled:

This property is different from Date Last Modified, which records any change to the properties of the object. If an operation to a document or annotation does not affect the content of that document or annotation, the Date Last Modified property is updated and the Date Content Last Accessed is not updated. The Date Content Last Accessed is not updated in the following situations:

Whenever content access date recording is turned on, you can experience an impact on performance, which increases as you increase the recording frequency.

Folders Filed In

The read-only Folders Filed In property returns the names of all folders that a document is filed in. The value is empty if the document is not filed in any folder. This property applies to all document-related classes and appears on the document property grid in Enterprise Manager.

Short or long custom string properties

You can define a custom string property to be stored in either a "short" or "long" database column. "Short" corresponds to nvarchar for SQL Server (with a maximum length of 4000 characters) or varchar2 for Oracle (with a maximum length of 1333 characters). "Long" corresponds to ntext for SQL Server or clob for Oracle (with a maximum length of 1073741823 characters for both).

Besides the maximum lengths permitted, the following differences exist between short and long strings:

The following additional operation-type restrictions exist for long columns (for full details see the Oracle or SQL Server documentation):

Hidden (Is Hidden) and Is Hidden Container

Is Hidden is a system property that indicates whether a class or property should be hidden from non-administrative users. This attribute simply provides a hint to the client application to not display the class property; the property is not in fact a security permission. If the application ignores the value of Is Hidden, the property is displayed the same as any other property. In Enterprise Manager, this property appears as the Hidden check box on More tabs of the property sheets of property templates.

Is Hidden Container is a custom property that is placed on the Folder class (and all its subclasses) if you install the Content Engine AddOn. It is used to hide a folder from the user in an application that reads and respects the value set for this property. In Enterprise Manager, this property appears in the folder object property grid and on the Property Definitions tab of folder classes.

See Hide a folder for more information about this property.

Expression

This field enables you to define property-based conditions for launching a workflow. This field accepts expressions using workflow properties, operators, and values.

For example, you can launch a workflow only if a document is created by a specific user and contains specific words in the title. You want to launch an approval workflow for documents in the selected class added by Tammy Smith containing "Sales Analysis" in the title. Assume that Tammy adds a document to the class that does not contain "Sales Analysis" in the title. The subscription can launch the workflow, based on the operator used:

Process Engine evaluates the Expression field to determine whether to launch a workflow automatically. When the value is true, Process Engine launches the workflow. Use the Content Engine properties to write a valid SQL expression for automatic workflow subscriptions.

For manual workflows, use the following guidelines:

NOTE  The Expression property, although still valid, has been replaced by the more recent properties Filter Expression and Filter Property in the Create a Subscription wizard and on the Configuration tab of the Event Subscription property sheet. If you have already assigned values to this property, you can access and edit it by using the property grid on the Properties page of the object property sheet or by using search and bulk operations.

Using alias IDs to enable multiple object store searches

If you plan to support searches that span multiple object stores for FileNet P8 clients, create alias IDs for the properties users can search on before assigning the property templates to a class. The alias IDs automatically propagate to the class. For more information about creating and working with alias IDs, see Create alias IDs and Multiple object store search.

Allows Foreign Object

This Boolean property indicates whether the property supports references to objects in another object store (referred to as a "foreign" object). When this property is set to true, an object belonging to any object store to which the user has access can be set as the value for defined property. The required class specified for the property must be defined in the object store of the target object. This property can only be set from the property template and is read-only on the actual property definition.

Settable system properties (Creator, DateCreated, DateLastModified, LastModifier)

This feature enables select users running system-level tools, such as import and migration tools, to set these four properties to Read/Write. For example, consider a federated document where the document is updated after its metadata on the original system was changed. Federation utilities must be able to set some of these properties after the document is created.
