Polifonia Ontology Network (PON)

The Polifonia Ontology Network (PON) provides a modular backbone of music ontologies to address both cultural heritage and more general queries in the music domain. As illustrated in the diagram below, PON v1.0 comprises 15 ontology module that are organised thematically (colours, horizontal view) and hierarchically, to highlight their dependencies (vertical view). At the bottom of the architecture lies our Core module (providing general-purpose elements of design, ODPs, and alignments) and the reused ontologies. Four foundational models provide interoperability across PON through their abstract design: Source, Instrument, Music Meta, and Music Representation. These are specialised and extended in the upper levels to add functionalities and contextualise specific domains.
