Quantities, Units, Dimensions and Types

Abbreviation: QUDT

General Information

The QUDT, or 'Quantity, Unit, Dimension and Type' collection of ontologies define the base classes properties, and restrictions used for modeling physical quantities, units of measure, and their dimensions in various measurement systems. The goal of the QUDT ontology is to provide a unified model of, 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. This OWL schema is a foundation for a basic treatment of units. The QUDT Ontologies, and derived XML Vocabularies, are being developed by QUDT.org. Originally, they were developed by TopQuadrant for the NASA Exploration Initiatives Ontology Models (NExIOM) project, a Constellation Program initiative at the AMES Research Center (ARC). They now form the basis of the NASA QUDT Handbook to be published by NASA Headquarters.

UK Data Archive
The UK Data Archive is an internationally acknowledged centre of expertise in acquiring, curating and providing access to social science and humanities data. We were founded in 1967, at the University of Essex, with the support of the then Social Science Research Council, with the aim of curating high-quality research data for analysis and reuse. The Economic and Social Research Council (ESRC) has continued to provide long-term commitment to the Data Archive and we are now a significant part of their UK data infrastructure. Since 2005 we have been designated a Place of Deposit by the National Archives, allowing us to curate public records. The UK Data Archive is the lead organisation of the UK Data Service, which provides unified access to the UK's largest collection of social, economic and population data. Funded by the ESRC, the UK Data Service provides access to regional, national and international social and economic data, support for policy-relevant research and guidance and training for the development of skills in data use.
