“…Several studies related to ontology technology for metadata have been carried out (O'Neill & Stapleton, 2022;Tibaut et al, 2018;Ziku, 2020)such as to create book metadata in a library (Agustini & Andri, 2014), ontology on the semantic web for purchasing a bicycle purchase case study (Sinaga et al, 2014) to the use of ontology to create tourist destinations in Bali (Pramartha, 2020). Research for the preservation of Balinese culture using a Balinese ontology approach has also been carried out (Pramartha et al, 2017;Pramartha & Kuan, 2022;Wardana & Pramartha, 2020)However, there has been no research to preserve the culture of Balinese lontar manuscripts using an ontological approach. Currently, Balinese lontar manuscripts need to be further developed in terms of preserving Balinese culture, because Balinese lontar manuscripts contain civilizational values and basic knowledge regarding various aspects of community life, which include belief, religion, social, health, traditional medicine.…”
