The importance of ontologies and linked open data in the ICH domain has already been acknowledged in various approaches (Chantas et al. 2018; Hou and Wang 2019; Ziku 2020). CultureSampo (Hyvönen et al. 2008), a flagship project introduced intelligent semantic web 2.0 technologies for cross-domain cultural heritage of the area of Finland. Europeana<ref xmlns="http://www.tei-c.org/ns/1.0" target="ftn3" n="3" />, the largest EU repository of cultural heritage data, uses linked open data for providing the data in an interoperable form. Regarding Greek ICH, important projects include iTreasures (Dimitropoulos et al. 2014), Wholedance (Camurri et al. 2016) and Terpsichori (Doulamis et al. 2017) demonstrating the important contributions of semantic web technologies for ICH preservation.
