OpenCMIS Client API

The OpenCMIS client layer provides an object oriented interface for easy consumption of the underlaying CMIS related layers. In additon to the CMIS specification the OpenCMIS client layer introduces a session concept which easily enables applications to get control on the client side cache behaviour.

The client layer consists of a client interface, common interfaces and a runtime implementation. The runtime maps the client interface to the provider layer and implements the session cache. All parts are exposed by following packages:

The following UML diagramm illustrates the main classes of the client API:

• SessionFactory This interface provides the entry point into the client API and is responsible to create a session object. Additionally it gives access to all repository info exposed by a CMIS provider. The runtime provides a default implementation for the SessionFactory interface.
• Session This is the main interface an applicaiton has to work with. A session object is related to a CMIS service provider and is attached to exact one repository. All data that is receiced throug the session interface can be cached in the session object in dependency of the concrete implementation which is behind.
• Repository Wrapper interface for the CMIS RepositoryInfo service.
• CmisObject The CmisObject interface represents the CMIS domain object.
• ObjectType This interface is base for all CMIS domain types like FolderType, DocumentType, PolicyType and RelationType. The derived interfaces are not shown in teh diagram.
• Folder This interface represents the CMIS folder domain object.
• Document This interface represents the CMIS document domain object.
• ContentStream this interface wrapps the content stream of a CMIS document.
• Policy This interface represents the CMIS policy domain object.
• Relation This interface represents the CMIS relation domain object.
