The disclosed method for coding data includes the exchange between the transmitter and the receiver, in the course of the session, of attributes of collaboration messages that are able to be used in said session and of indices associated with these attributes. In various implementations, the attributes and their indices may be used by these pieces of equipment for updating a shared dictionary of indexed attributes. Upon coding, the attributes of the collaboration messages may be substituted with their indices; and upon decoding, the inverse operation may be carried out. The shared dictionaries may be destroyed at the end of the session.
