Abstract

A method and system for exchanging at least one data value between a first device and at least one second device, including providing at least one data structure at the first device, the data structure including at least one descriptive field and an associated at least one data value field, the at least one data value field including the least one data value, the at least one descriptive field including a usage type field having usage type data to associate the at least one data value field with a data type, transmitting the at least one data structure from the first device to the at least one second device, and, based on at least the usage type data, at the at least one second device, extracting the at least one data value from the at least one data value field.

Claims3

Dependent claims

A method of exchanging data between a first device and at least one second device, the method comprising:

receiving at the first device a set of data packets from the second device, each data packet having at least one descriptive field and data, where at least one descriptive field indicates that the data packet is of a structure taken from a listing of structures including a template structure, a data-only structure, and a complete structure,
for each of a plurality of said received data packets in which the at least one descriptive field indicates the data packet is a template structure, the first device extracting a template identification from a second descriptive field of the data packet and storing the data as a template associated with the template identification, the template for extracting data from data packets and,
when the at least one descriptive field indicates the data packet is a complete structure, the first device extracting the data according to a data structure type of the complete structure.
