Wikidata and the Thesaurus Nuovo Soggettario: Together to Build a Domain Ontology in the Field of Photography

The project aims to build a domain ontology on photography in Wikidata, in dialogue with the Nuovo soggettario of the National Central Library of Florence, the official Italian subject indexing tool for resources of various kinds. In the Nuovo soggettario, terms are organized in a hierarchical structure (from the most general to the most specific), while in Wikidata, entities are defined through their properties and relationships. Aligning conceptual hierarchies and enriching both databases with new terms and links to other Knowledge Organization Systems (KOSs) highlights the value of participatory semantic modeling to enhance interoperability between tools and cultural resources.
