Abstract

This IESO's Measure module gathers units of measure needed for the MAS-Society project. It is a separate module as it describes concepts and relations useful for various IESO modules.

1. Description

The IESO's Measure module describes measures, measurement values, types of measures, and units of measure. A measurement is composed of a type of measure, at least a measurement value and respective unit of measure. A type of measure is related to a unit of measure. A measurement value is described by exactly one literal value and the respective unit of measure. A measurement can be related to several measurement values with different units; as long as they derive from the same SI unit, e.g. a power measurement can have a value of 2000W and another of 2kW, representing the same value in different magnitudes. Additionally, this ontology defines a unit converter template class to provide conversion templates for automatic values conversion.

The IESO’s Measure module describes measurements, measurement values, types of measures, and units of measure. This module received input from the Quantity, Unit, Dimension, and Type (QUDT) ontology and SAREF core. A Measurement is composed of a Type of measure, at least a Measurement value, and the respective Unit of measure. A Type of measure is also related to a Unit of measure, and a Measurement value is described by exactly one literal value and the respective Unit of measure. A Measurement can be related to several measurement values with different units; as long as they derive from the same SI unit, e.g., a power measurement can have a value of 2000W and another of 2kW, representing the same value in different magnitudes. Additionally, this ontology defines a Unit converter template class to provide conversion templates for automatic values conversion. This module conceptualizes knowledge transversal to the various IESO and applicational ontology modules, being reused and extended as needed.
