The ClassDescription object containing the property metadata for the EngineObject.

Specifies the unique identity of this external replicated object, relative to an external repository in which a replica of the object exists.

A representation of the Globally Unique Identifier (GUID), a unique 128-bit number, that is assigned to this Content Engine object when the object is created. When converted to a string, the Id property is typically depicted as 32 hexadecimal characters enclosed by brackets in the following format: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}. For example, {3F2504E0-4F89-11D3-9A0C-0305E82C3301}.

For IUser and IGroup classes, the Id property takes the value of the Security Identifier (SID) rather than the 128-bit GUID. The string representation of the SID is in this example format: S-1-5-21-1559522492-2815155736-3711640725-55269. When Active Directory is used as the directory service for IBM Content Cortex, IUser.Id and IGroup.Id always return the current SID for the principal, even if this user or group has only historical SIDs populating the Active Directory server.

For a given property representation, the Id property has the following characteristics:

• PropertyDescription.Id is equal to PropertyTemplate.Id, which is equal to PropertyDefinition.PrimaryId.
• PropertyDefinition.Id is not equal to PropertyDefinition.PrimaryId.
• PropertyDefinition.Id is not equal to PropertyDescription.Id.

For a newly created document object, you can override the Id property of its associated VersionSeries object before you save or check in the document for the first time.

The IProperties collection of properties for the EngineObject.

For a replicated object in an external repository, specifies provider-specific data for the object.

For an advanced storage area, this property stores internal data about the content item to be processed by a content queue sweep (ICmContentBackoutQueueSweep, ICmContentDeletionQueueSweep, or ICmContentReplicatonQueueSweep).

Data stored here is not queryable.
