ABSTRACT:
A method for encoding a group of several structured fragments includes analyzing structure schemas of the fragments in order to obtain sequences of executable instructions for each component of the schemas. The instruction sequences are executed on the structured fragments so as to obtain an encoded binary stream containing the control codes and the information elements values of the fragments. The values of the information elements of the fragments in data blocks are distributed as a function of the respective types of the elements. The respective positions in the structure block are stored in a pointer table for each fragment and in the data blocks of the control codes and the information element values of the fragment. Compression algorithms are applied to the blocks adapted to the contents thereof, and the contents of the pointer table and data blocks are concatenated into an encoded binary container.
