From https://labs.etsi.org/rep/saref/saref-portal/-/issues/4 To aid in identifying modelling discrepancies, here is the list of same-named SAREF entities that have differing entity types. The problem is user confusion as to which type of ontological entity to choose between, say either DatatypeProperty or ObjectProperty. [subClassOf relations are indicated within square brackets.] Recall that DatatypeProperty relates individuals to literal data as a range, and ObjectProperty relates individuals to other individuals also by range. **{EntityName Extension EntityType SubClassof/SubPropertyOf} Comment** ------------------------------------------------------------------------- - {Frequency saref4envi owl:Class [owl:Thing]} <<No Comment>> - {Frequency saref4envi owl:NamedIndividual [saref:Property]} "An individual representing the property frequency." - {frequency saref4ehaw owl:DatatypeProperty [s4ehaw:ComputingPower]} "The frequency is the number of instructions an embedded processor - within a health device - can perform per second (MIPS)." ---------------------------------------------------------------------------------------------- - {Height saref4auto owl:Class [saref:Property]} "A Property of interest for the automotive domain." - {Height saref4envi owl:NamedIndividual [saref:Property]} "An individual representing the property height." - {height saref4bldg owl:ObjectProperty [N/A]} "Height of the vibration isolator before tha application of load.
