Simple Measurement Ontology

Other names: SIMON

The SImple Measurement ONtology (SIMON) is a small vocabulary (3 top level classes: PunnedClass, Measurement, and Unit) to represent measurements and units. It uses the pattern to represent N-ary relations and a recursive structure to make the representation of various measurements and units (e.g., "5 kilograms", "4 miles per hour", "5 meters per second per second" straight forward and obvious. It utilizes the Semantic Web Rule Language (SWRL) to automatically order measurements of the same type (e.g., Speed) regardles of units. E.g., that 5 kilometers per hour is greater than 5 meters per hour. It does this by transforming all measures of a specific type (e.g., distance, mass, speed, acceleration) to canonical units. The canonical units can be modified by changing a few rules. I also include on the github page some SPARQL transformations that generate the rdfs:label for each measurement instance so the developer doesn't have to take the effort and potential error prone risk of doing this manually. The version included here is the version after the SWRL rules have run and with the inferences exported and also after the SPARQL transforms have generated all the rdfs:label values. Although there are other vocabularies that address this problem they are either much more complex (addressing many additional issues besides units and measures) and/or do not automatically order measures of different units.
