The properties of the class E54 Dimension allow for expressing the numerical approximation of the values of an instance of E54 Dimension. If the true values belong to a non-discrete space, such as spatial distances, it is recommended to record them as approximations by intervals or regions of indeterminacy enclosing the assumed true values. For instance, a length of 5 cm may be recorded as 4.5-5.5 cm, according to the precision of the respective observation. Note, that interoperability of values described in different units depends critically on the representation as value regions.\n\nNumerical approximations in archaic instances of E58 Measurement Unit used in historical records should be preserved. Equivalents corresponding to current knowledge should be recorded as additional instances of E54 Dimension as appropriate.\n\nExamples:\n- currency: \u00A326.00\n- length: 3.9-4.1 cm\n- diameter: 26 mm\n- weight: 150 lbs\n- density: 0.85 gm/cc\n- luminescence: 56 ISO lumens\n- tin content: 0.46 %\n- taille au garot: 5 hands\n- calibrated C14 date: 2460-2720 years, etc\n\nIn First Order Logic:\nE54(x) \u2283 E1(x)"@en ; rdfs:subClassOf ecrm:E1_CRM_Entity , _:b10036 , _:b10175 , _:b4747111 . @prefix xsd: . @prefix skos: . ecrm:E54_Dimension skos:notation "E54"^^xsd:string . _:b10036 rdf:type owl:Restriction ; owl:onProperty ecrm:P91_has_unit ; owl:cardinality "1"^^xsd:nonNegativeInteger . _:b10175 rdf:type owl:Restriction . @prefix efrbroo: . _:b10175 owl:onProperty efrbroo:CLP43i_should_be_dimension_of ; owl:qualifiedCardinality "1"^^xsd:nonNegativeInteger ; owl:onClass efrbroo:F3_Manifestation_Product_Type . _:b4747111 rdf:type owl:Restriction ; owl:onProperty efrbroo:CLP43i_should_be_dimension_of ; owl:cardinality "1"^^xsd:nonNegativeInteger .
