The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Use of a digital scale--i.e. one using alphanumeric characters as opposed to the relative position of needles or 'hands' (as with a clock) against a background scale to display data--for measuring the weight of an organ, tissue or other body part after it has been removed from the body. The weight of an object is its heaviness, that is, the force exerted on it by gravitational force which is proportional to its mass.
