Clinical Metadata Exploration Ontology (CMEO) clinical data category subset is record of process clinical event record An information content entity (a data item, e.g. a variable or record) that documents the occurrence of a clinically relevant event for a patient at a point in time or over a time interval (e.g., a death, a hospitalization, a myocardial infarction), and that is about the corresponding real-world process. CMEO mints the information/record layer, not the occurrent. This class is the record or variable about the event; it 'is about' (IAO:0000136) the underlying process (BFO:0000015). The real-world occurrence itself is not minted in CMEO but referenced via 'is about' and, where relevant, cross-referenced to process ontologies (e.g. OAE for adverse events). clinical event data entity
