www.oasis-open.org OASIS Quantities and Units of Measure Ontology Standard (QUOMOS)An Introduction
Outline • Goals of the QUOMOS Standard • Why use an ontology? • What QUOMOS is NOT trying to do • Liaisons and existing work
Goals of the QUOMOS Standard • Develop a core set of ontology modules covering: • Quantities • Units • Scales • Develop extension mechanisms for non SI units and other measurement systems • Provide a consistent framework for current activities modeling units of measure • Dimensions • Base and derived SI units • Relationships between units
Why Use an Ontology? • Ontologies allow the explicit specification of the multiple possible interpretations of concepts so that people can recognize commonalities and differences in the semantics of the concepts that they use.
Why Use an Ontology? • An Ontology (in this sense) is a computer readable specification, thereby enabling: • Automated consistency checking • Reasoning – i.e. deducing logical implications of assertions. • Incorporation directly into scientific and engineering software tools
What QUOMOS is NOT trying to do • QUOMOS has no desire to modify any of the definitions put into place by existing authorities. • Rather QUOMOS seeks to formally encode those definitions in terms of logic statements
Liaisons • The QUOMOS committee intends to maintain good communications with: • BIPM (International Bureau of Weights and Measures) • ISO TC12 • ISO/IEC 80000 • VIM (International Vocabulary of Metrology) • UnitsML • UCUM (Unified Code for Units of Measure) • UNECE Recommendation 20 • and others as appropriate
Existing Units Ontologies • QUOMOS plans to create a framework which can accommodate, and help with interoperation between existing units ontologies such as: • Sweet (NASA) • QUDT (TopQuadrant / NASA) • QUDV (OMG-SysML)
