Change token support

IBM® Content Management Interoperability Services for FileNet® Content Manager (IBM ECM CMIS) supports the cmis:changeToken property for only documents and folders. IBM ECM CMIS does not support the property for domains, relationships, repositories, or content streams.

OASIS CMIS specification

The OASIS CMIS specification defines the cmis:changeToken property to provide optimistic locking to prevent client applications from updating out-of-date objects.

IBM ECM CMIS implementation

IBM CMIS for FileNet Content Manager supports the cmis:changeToken property for only documents and folders.

The cmis:changeToken property is included in the object metadata for the cmis:document type and the cmis:folder type. The cmis:changeToken property maps to the IBM Content Cortex UpdateSequenceNumber property.
