In the current work, geo-semantic web technologies are being utilized in order to formalize and document all the data regarding the ICH of Greek traditional dances and songs. Ontologies are being used for the conceptualization of the information and its provision as linked open data. For increasing interoperability and enabling the linkage with existing resources, already developed ontologies and schemas such as the DOLCE ontology (Borgo and Masolo 2010), the CIDOC CRM (Crofts et al. 2008) are being adopted. For the formalization of specialized domain concepts, the Greek Intangible Heritage Ontology (GIHO) is being developed with special focus on the spatial and temporal parameters. For enabling a better understanding of the data and providing more efficient ways of making it available to a wide range of users (either with a technical or non-technical background), a map-based web platform is being developed in which the end users will be able to pose complex queries. The Ontop-spatial (Bereta et al. 2016) and Sextant (Nikolaou et al. 2015) tools developed by the University of Athens, are being used for the processing and visualization of complex spatiotemporal thematic queries such as “Show me all places where dances with rhythms of 9/8 exist” or “Show me all the places where songs with the same text and different music exist”.
