Data communications are enabled to be performed between first and second computer systems without having to match data types at the first and second computer systems. A first data type is associated with a request for a resource. The request for the resource is transmitted from a first agent at the first computer system to a second agent at the second computer system. The resource is instantiated at the second computer system according to a second data type that is different from the first data type. The resource is received by the first agent from the second agent. The received resource is materialized into an instance of the first data type using the first agent.
