Although the goal of achieving semantic interoperability of Electronic Health Records (EHRs) is pursued by many researchers, it has not been accomplished yet. In this paper we present a proposal that smoothes out the way towards the achievement of that goal. In particular our work focuses on medical diagnoses statements. In summary the main contributions of our ontology-based proposal are the following: First, it includes a canonical ontology whose EHR-related terms focus on semantic aspects. As a result, their descriptions are independent of languages and technology aspects used in different organizations to represent EHRs. Moreover, those terms are related to their corresponding codes in well-known medical terminologies. Second, it deals with modules that allow obtaining rich ontological representations of EHR information managed by proprietary models of health information systems. The features of one specific module are shown as reference. Third, it considers the necessary mapping axioms between ontological terms enhanced with so-called path mappings. That feature smoothes out structural differences between heterogeneous EHR representations, allowing proper alignment of information.
