www. oasis-open. org OASIS Quantities and Units of Measure Ontology Standard (QUOMOS) An Introduction v 1. 00 - Rev. D / April 2010

Outline Goals of the QUOMOS Standard Why use an ontology? What QUOMOS is NOT trying to do Liaisons and existing work 4

Goals of the QUOMOS Standard Develop a core set of ontology modules covering: • Dimensions • • • Quantities Units Scales • • Base and derived SI units Relationships between units Develop extension mechanisms for non SI units and other measurement systems Provide a consistent framework for current activities modeling units of measure 6

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. 8

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 10

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 12

联络人 QUOMOS 技术委员会打算与下列方面保持良好 的沟通： 国际计量局（International Bureau of Weights and Measures， BIPM ） ISO TC 12 ISO/IEC 80000 国际计量学词表（International Vocabulary of Metrology， VIM ） Units. ML 计量单位统一代码（Unified Code for Units of Measure， UCUM ） 联合国欧洲经济委员会第 20号建议文件－国际贸易测量单位（ UNECE Recommendation 20） 以及其他的合适方面 13

Liaisons The QUOMOS committee intends to maintain good communications with: BIPM (International Bureau of Weights and Measures) ISO TC 12 ISO/IEC 80000 VIM (International Vocabulary of Metrology) Units. ML UCUM (Unified Code for Units of Measure) UNECE Recommendation 20 and others as appropriate 14

Existing Units Ontologies QUOMOS plans to create a framework which can accommodate, and help with interoperation between existing units ontologies such as: sci. Units of SWEET (NASA) QUDT (Top. Quadrant / NASA) QUDV (OMG-Sys. ML) 16
