The doctoral project focuses on the creation of a genetic-evolutionary digital critical edition of the Codice degli abbozzi, with the aim of outlining a critical-diachronic representation of the texts. Through the description and encoding of textual variants, the edition seeks to account for the compositional processes and internal rewriting phenomena that characterize Petrarch’s poetic genesis, while at the same time situating the manuscript within the textual tradition of the Canzoniere and the Trionfi. The digital dimension serves as the privileged tool for representing this process, within a methodological framework that combines authorial philology and Digital Humanities. The genetic-evolutionary perspective makes it possible to overcome the dichotomy between the final text and the text in progress: the digital edition thus takes shape as an open representation of a process, in which each stage acquires its own autonomy and interpretive value. This approach entails a rethinking of the traditional critical apparatus: instead of a static system of footnotes, the commentary becomes a network of interactive relations. The tools employed include: the TEI Publisher platform; XML for encoding according to TEI Guidelines; ODD, HTML, CSS, and JavaScript for transforming the encoding into a graphical interface; Adobe Illustrator and FontForge for the creation of a custom font; and OWL, Protégé, and SPARQL for the construction of a semantic ontology.
