**Affects:** SAREF **Situation:** SAREF contains axiom Range( hasValue xsd:float ). However, there are other datatypes for measurements. Some domains require the precision of doubles. One may use the cdt:ucum datatype to associate a value. The number of persons in a building would be an integer. Other types of property may be thought about, like vectors (x, y, z acceleration), matrices (strain in deformable solids) **Proposal:** remove the axiom. Update the definition of hasValue to specify that numeric values are expected to enable reasoning **Status:** agreed during SmartM2M-2nd RG Meeting about 2 NWIs SAREFv3 and SAREF Com Framework V2 2019-05-06
