Abstract/Summary
|
-
In this paper, we introduce "Decentralised semantics", the segregation of task-specific, content-addressable objects, as a solution for harmonising quantitative data from medical devices within and across distributed health data ecosystems. Overlays Capture Architecture (OCA) is a semantic architecture that offers a scalable harmonisation solution between data models and data representation formats from different sources while providing a roadmap to resolve privacy-compliant data sharing between healthcare actors, including regulatory agencies. As an illustration, we introduce the concept of applying "overlays" as a transformation mechanism to convert source measurements from medical devices to a standard system of measures and units for improved insights-driven applications.
