Industry 4.0 requires standardized information models for heterogene- ous platform integration. Two standards for interoperability are IEC 62541 - a machine-to-machine communication protocol expressed in OPC Unified Archi- tecture (OPC UA) format - and IEC 62714 to describe production plants or plant components expressed in AutomationML format. Despite their wide adoption, these languages lack formal semantics for automatic data interpretation. This work describes a Systematic Mapping Study focused on recent studies on the transformation between the OPC UA and AutomationML languages and OWL or RDF. Articles on conferences and journals from 2015 onwards are queried and analyzed from the Scopus, IEEE, and ACM databases. The study is limited to articles written in the English language and published in journals. From 43 doc- uments, 16 are retained following the inclusion and exclusion criteria. As a result of this study, the main challenges facing Industry 4.0 are identified. These are the lack of support for the ontology engineering tasks performed by the knowledge engineer, the representation of the semantic digital twin, data duplication, and communication overhead. Germany concentrates 87 % of the involved articles on the subject.
