This article presents ruptures and convergences in the processing of Scientific and Technical Information (STI), issued from emerging standards and norms for digital documents. The area of application relates to the activity of the researchers in molecular biology, and more precisely genomics. To apprehend the changes in the processing of STI, three kinds of objects are to be considered: biological objects (that include physical entities, concepts, and their relationships: a physiological fonction, a regulation, a gene, a molecule, etc .), the computer languages and tools, and finally, the digital documents. To mean the ruptures and convergences in the treatment of STI, the above-quoted objects are analyzed according to three phases : (i) An upstream phase of standardization, relating to the emergence of standards or norms, creating a rupture in the pre-existing processing of STI. (ii) A phase of standardization related to the processing of STI, which shows a possible processing of digital documents taking into consideration convergence from standards of the previous phase. (iii) A downstream phase of standardization, which shows new uses and standardization needs, directed towards knowledge integration, cooperative environments, with ad hoc projects and groups creation. We conclude this article by outlining some features of the changes that operated.
