The QUDT, or 'Quantity, Unit, Dimension and Type' collection of ontologies define base classes, properties, and instances for modeling physical quantities, units of measure, and their dimensions in various measurement systems. The goal of the QUDT collection of models is to provide a machine-processable approach for specifying measurable quantities, units for measuring different kinds of quantities, the numerical values of quantities in different units of measure and the data structures and data types used to store and manipulate these objects in software. A simple treatment of units is separated from a full dimensional treatment of units. Vocabulary graphs will be used to organize units for different disciplines.
The ontololgy architecture depicts the dependencies between the vocabularies and schemas of the QUDT release 1.1 set of OWL graphs.
Yellow rectangles depict vocabularies and blue rectangles depict schemas. Clicking on a node in the diagram takes you to the catalog entry for the graph. The links represent import relationships. Every graph imports 'VAEM'.
