Utilizing Real-World Data (RWD) for secondary use is still an open issue. Initiatives like OHDSI aim to tackle it by introducing a common data model (OMOP-CDM) to which data providers can opt to convert their data. While OMOP-CDM supports data interoperability and maintains a degree of intertwined terminologies/vocabularies, does not utilize the benefits of the Semantic Web technical paradigm. This paper presents an effort to convert the OMOPCDM to RDF format to further enhance its linked data capabilities.
