In an information processing method, objects are given unique labels expressed by a tree structure by a plurality of nodes. The label includes (A) name information showing node names from a highest order node to a lowest order node and (B) a storing position of the object. Each node corresponds to data required for a process or a software application. Information expressed in an external language is transmitted and received to and from devices in a network. A received label expressing an object is processed such that a process of calling-up, writing, deletion, and partial change with respect to each node of the object is performed. At least one node of the object is acquired via the network expressed in the external language together with a request for processing. The designated object is converted into information expressed in an internal language while preserving the acquired node tree structure.
