In genetic criticism, scholarly editing, authorial philology and, more generally, for the study of authorial manuscripts and writing processes it is essential to order and classify the textual witnesses and their relationships. The two datasets documents so-called ‘genetic networks’, representations of the genetic entities (witnesses, publications, dossiers) and of their relationships, modelled according to the GENO 1.0 ontology. The datasets contain genetic networks of the works of two Swiss authors: the main publications of Gustave Roud (1897-1976) and the short story “En mer” by Bernard Comment (1960).
