There are several best practices for working with documents that are federated by using IBM® FileNet® CFS for Content Integrator.
Altering the state of the current version of a federated document in the Content Platform Engine object store causes future import of the version series to fail. Do not perform the following state changes on the current version of a document if import from the source repository might be required again:
If property values are changed on a document in the target Content Platform Engine object store, those changes might be overridden when you import the document again.
Updates to properties in the target repository are controlled by the Date Last Modified document property. If the Date Last Modified property is mapped to a source property, the date value of the source document is compared to the Date Last Modified property of the target document, and the target property values are overridden if the source values are more recent.
If the Date Last Modified property is not mapped to a source property, the target property values are always overridden by the source values if there are changes to the source document after the previous federation run. This behavior can also be achieved by setting the Federation Update Has Priority property of the IBM Content Integrator fixed content device to True (the default value for this property is False). When this property is set to True, source properties always overwrite target properties regardless of the outcome of the Date Last Modified property value comparison.
The content federation import agent does not support versioning documents that contain property values that are both required and are not copied to reservation. Do not define properties as Value Required and not Copy to Reservation if you work with a source repository that supports versioning.
Because Content Platform Engine does not have control over the content in source repositories, and deletes are not propagated from a source repository to Content Platform Engine, deleting a document from a source repository breaks the federated document in Content Platform Engine.
Do not change security on a source document in a way that prevents Content Platform Engine from reading, locking down, or deleting the document.
