Ontology mapping is needed to explicitly represent the relations between several ontologies, which is an essential task for applications such as semantic integration and data transformation. Currently, there is no standard for representing mappings. Instead, there are a number of technologies that support the representation of mappings between the ontologies. In this paper we introduce a set of mapping categories that were identified based on requirements for the data integration projects of an industry partner. An evaluation of available technologies for mapping representation regarding the support for introduced mapping categories has been performed. The results of the evaluation show that the SPARQL Inference Notation would fit the best in the described use case scenario.
