Intorno all'ontologia POGO (Philology-Oriented Graphematics Ontology): classificazione dei grafemi e modellizzazione delle abbreviazioni

The article presents two aspects of the POGO ontology (Philology-Oriented Graphematics Ontology), namely the classification of graphemes in alphabetic writing systems and the modeling of medieval abbreviations. POGO formalizes the author’s reflections on digital graphematics — that is, on the representation of the signs of a writing system in a computational environment — within the framework of a broader methodological work on the digital scholarly editing of Latin texts transmitted by premodern manuscript witnesses. The article refers to version 1 of POGO (release POGO v1.0.1, https://github.com/vedph/graphematics/releases/tag/v1.0.1) and, in its conclusion, outlines some directions for future work toward a possible evolution to a version 2 — or an integration of POGO with other ontologies — that would revisit certain issues, especially those concerning the concept of the alphabetic letter (or 'alphabeme') and relations of allography.
