Simple Shared Object An Architectural Pattern for Simple Object Sharing

This paper describes a pattern for object sharing across different address spaces. The pattern is intended for applications where collaborators on clients across a network work closely together. The Simple Shared Object pattern allows distributed applications to create, modify and delete shared objects on a corresponding server. The clients have copies of shared objects they use in their own address spaces. All modifications made to the primary copies on the server are propagated to clients having copies in their address spaces. The pattern is not designed for high traffic communication between concurrent running applications. Rather, it is designed for applications where some objects have to be shared across a network and where shared objects have to be synchronised and informed whenever a shared object changes.
