OxiEphemeris Vocabulary

The controlled vocabulary behind OxiEphemeris, a pure-Rust astronomy & Western-astrology engine. It defines the classes and properties (an OWL ontology) and the fixed sets of terms — zodiac signs, planets, aspects, dignities, house systems, and more (SKOS concept schemes) — that every chart, synastry, and composite document refers to.

Content negotiation

The canonical IRIs are extension-less and dereference by Accept header — request Turtle, N-Triples, or this HTML page from the same URL:

Concept schemes

Thirteen fixed vocabularies. Each concept carries bilingual skos:prefLabel (en / ja) and, where one exists, a skos:exactMatch to Wikidata.

Alignment

The vocabulary reuses established terms rather than reinventing them: SKOS for concepts, PROV-O for provenance, QUDT for units, WGS84 for observer coordinates, OWL-Time for epochs, and Wikidata cross-links on the concepts.

Dataset metadata

The dataset is described with VoID and DCAT — triple counts, distributions, example resources, and the link set to Wikidata — so data catalogues can discover and index it: VoID / DCAT description (Turtle · N-Triples), also at the conventional /.well-known/void.
