Federated ontologies

VsML bridges five external vocabularies

OCX

Structural and dimensional vessel data — lengths, breadths, draughts, hydrostatic coefficients

SFI

SFI Index System

Ship systems reference designators — propulsion, navigation, safety, deck equipment

ORG

W3C Organization

Organizational concepts — owner, faculty, classification society, port of registry

PROV

Provenance and documentation — evidenced by drawings, specifications, arrangements

OM

Units of Measure

Measurements and units — hasValue, hasUnit for quantitative vessel parameters

Instance data

Research vessel Gunnerus

Vessel

RV Gunnerus

RDF instance data for the research vessel Gunnerus, operated by NTNU. Covers 30 grounded concepts across 6 relationship types — equivalence, spatial, functional, mathematical, business, and cross-ontology triples.
