Risk information standards and interoperability

Risk information travels between organisations only when it is findable, citable and checkable.

Twin figures for the central Apennines: L'Aquila, Amatrice and Norcia, counted from its layers at their stated dates.

Twin builder and simulator.

For Risk information standards and interoperability: the faculty's twin of L'Aquila on the planet map, the globe and in 3D. Pick a generator, switch layers, run the instruments; every layer prints its provider and date.

The central Apennines: L'Aquila, Amatrice and Norcia: a flat plan of the faculty twin. Terrain 24 to 2,805 m; 3 reference earthquakes, M6.2 to M6.6; Earthquakes M4.5 and above, past week (live): live, loads in the twin; USGS ShakeMap intensity contours: live, loads in the twin. Contours every 500 metres from the elevation grid; reference earthquakes as marks.
The central Apennines: L'Aquila, Amatrice and Norcia, Italy. Flat plan of the same data: relief, the three reference epicentres with magnitude and depth, and the numbers below; the sampler's figure shows one precomputed field with its parameters. The 3D twin opens on devices with WebGL once its data and library have been checked.

Credits and dates per layer are listed under the stage. Relief in the twin is exaggerated ×1.5 for legibility.

The discipline in brief.

The discipline teaches persistent identifiers and the UNI, versioning and corrections, metadata profiles under STAC, DCAT and PROV-O, licence and provenance metadata, honesty and epistemic state fields that say whether a value is observed, modelled, estimated or unknown, naming and public identity rules, and how a standard is adopted and its conformance shown, with the Nexus Standards as the worked example that evolves through its canonical repository. A graduate can profile a dataset, assign and resolve its identifiers and run the conformance checks that show a typed state.

This area covers the standards that make risk information findable, citable and checkable across organisations: persistent identifiers, dataset and metadata profiles, naming rules, and how a standard is adopted and its conformance shown. It is taught in the department of Geospatial and Risk Data Science, Faculty of Risk Science and Methods, through courses still to be authored and 1 more that also teach it.

What the discipline covers.

8 subtopics, taught across its courses and labs.
