Ontology of units of Measure

The OM ontology provides classes, instances, and properties that represent the different concepts used for defining and using measures and units. It includes, for instance, common units such as the SI units meter and kilogram, but also units from other systems of units such as the mile or nautical mile. For many application areas it includes more specific units and quantities, such as the unit of the Hubble constant: km/s/Mpc, or the quantity vaselife. OM defines the complete set of concepts in the domain as distinguished in the textual standards. As a result the ontology can answer a wider range of competency questions than the existing approaches do. The following application areas are supported by OM: Geometry; Mechanics; Thermodynamics; Electromagnetism; Fluid mechanics; Chemical physics; Photometry; Radiometry and Radiobiology; Nuclear physics; Astronomy and Astrophysics; Cosmology; Earth science; Meteorology; Material science; Microbiology; Economics; Information technology; Typography; Shipping; Food engineering; Post-harvest; technology; Dynamics of texture and taste; Packaging

OM本体论提供了代表定义和使用度量单位的不同概念的类、实例和属性。例如，它包括国际单位制中的常见单位，如米和千克，同时也涵盖了英里或海里等其他单位系统。对于众多应用领域，OM还包括更具体的单位和量，例如哈勃常数的单位：km/s/Mpc，或vaselife这一量。OM定义了该领域的完整概念集，其区分方式与文本标准相一致。因此，该本体能够回答比现有方法更广泛的胜任力问题。OM支持以下应用领域：几何学；力学；热力学；电磁学；流体力学；化学物理；光度学；辐射学及辐射生物学；核物理；天文学与天体物理学；宇宙学；地球科学；气象学；材料科学；微生物学；经济学；信息技术；排字学；航运；食品工程；收获后技术；质地和味道的动力学；包装。
