Abstract: This manuscript introduces J2RM : a tool to process mappings from JSON data to RDF triples guided by an OWL2 ontology structure. The mappings are defined as annotation properties associated with each ontology entity of interest. They are embedded in an ontology file so that they can be readily deployed and shared to automate RDF-graph creation. In this paper, we motivate the need for such mappings, describe some of their definitions on a use case example, present the formal grammar of the mapping language, and explain how these mappings work. We conclude with a discussion of the key aspects, main contributions, and future improvements.
