QUDT CATALOG - Quantities, Units, Dimensions and Data Types Ontologies

August 22, 2019

Catalog URI= http://www.qudt.org/catalog/QC_QUDT-R2.1

QUDT Ontologies: Schemas and Vocabularies

QUDT models are based on dimensional analysis expressed in the OWL Web Ontology Language (OWL). The dimensional approach relates each unit to a system of base units using numeric factors and a vector of exponents defined over a set of fundamental dimensions. In this way, the role of each base unit in the derived unit is precisely defined. A further relationship establishes the semantics of units and quantity kinds. By this means, QUDT supports reasoning over quantity kinds as well as units. QUDT models may be translated into other representations for machine processing, or other programming language structures according to need.

Note that the separate quantity kind vocabulary graphs have been combined into a single graph, so the earlier ones have been marked as deprecated and will eventually be removed from the catalog listing.

Catalog content is organized in the following sections:

  1. Schemas
  2. Vocabularies (instance graphs)
