Abstract
This research paper introduces RDF-star technology as a solution to the limitations of standard RDF in representing and querying metadata-oriented travel accounts, especially historical ones. By enabling statements about statements and directly embedding metadata within RDF triples, RDF-star enhances query efficiency and simplifies data modeling, offering a more streamlined approach to constructing complex knowledge graphs. This paper introduces the RDF-star-based JourneyStar ontology, explicitly designed for representing travel data and metadata. Through examples, we demonstrate the application of this ontology in constructing a knowledge graph representing journeys outlined in Jacob I Bernoulli’s travel diary, Reisbüchlein.
