The O&M ontology (ISO 19156) defines Time Series Observation  as an “observation whose result is a time-series”, while both Hl7 aECG and DICOM standards define the Series element as a sequence of data sharing a common frame of reference. In SAREF4health we termed this concept as Time Series Measurements since this sequence of data refers to time series measured by a device.  Notice that in this term we avoided prefixing with ECG because this concept can be applied to other types of data." ;

For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called \"watt\". Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of the Smart Appliances ontology, but this list can be extended."@en ;
