The wave of ontology has spread drastically in the cultural heritage domain. The impact can be seen from the growing number of cultural heritage web information systems, available textile ontology and harmonization works with the core ontology, CIDOC CRM. The aim of this study is to provide a base for common views in automating the process of mapping between revised TMT Knowledge Model and CIDOC CRM. In this study, manual mapping was conducted to find similar or overlapping concepts which are aligned to each other in order to achieve ontology similarity. Although there are several problems encountered during mapping process, the result shows an instant view of the classes which are found to be easily mapped between both models.
