Although Culture Heritage is considered one of the domains that attract researchers from different disciplines, however, there is a lack of semantic meaning and interoperability between different heterogeneous sources that have different structures, stored in different formats and placed in different geographical locations. In addition to that, most of the datasets are available in spreadsheet format. The paper on hands aims to improve the semantic mapping of different datasets belonging to the Egyptian museums via proposing and implementing an architecture that enriches these datasets via applying of Linked Open Data techniques depending on two different mapping methodologies; they are CIDOC-CRM and R2RML, showing that they giving better results instead of using each one separately.
