The purpose of the implementation of nursing terminologies is to capture and process meaningful health data wherein facts about patients and nursing care can be recorded and inferences for nursing care, patient outcomes and associations with all care delivered by the interprofessional team can be made. This paper describes the clinical information landscape, implementation of semantic content, and competencies required for nurses. Health data can be outlined in a high level clinical information ecosystem where nursing terminologies can be represented for implementation. This ecosystem consists of both the structural and dynamic aspects of the support of care.
