ornavi

Ornavi is a term used in some speculative design and academic discussions to denote a hypothetical, open-source platform for multi-modal navigation. In these contexts, Ornavi is conceived as a modular software stack intended to coordinate routing across road, rail, maritime, and air segments, as well as pedestrian and last-mile modes. The concept aims to address interoperability among diverse map databases, real-time data feeds, and constraints such as timetables, vehicle capacities, and safety rules.

Origin and scope: The name is not tied to a single organization and does not refer to a widely adopted standard. It appears in theoretical analyses and fiction as an exemplar for how a universal navigation layer might work, rather than a vendor-specific product.

Architecture: A typical Ornavi design features a core routing engine, a data model for maps and events, and client libraries for various platforms. The data model is imagined as layered: geometry and topology, dynamic attributes like traffic and incidents, timetable and sovereignty constraints for regulated modes, and privacy-preserving mechanisms. Routing algorithms include time-expanded graphs, multi-criteria optimization, and heuristics for multi-modal paths.

Applications and status: In simulations and narrative settings, Ornavi enables researchers and writers to explore interoperability challenges, data governance, and user-centric privacy. It is not an official standard or widely deployed system in the real world; references are conceptual.
