Units of measure

[GoogleCodeExporter]

Description of the issue or change request

Units of measure is currently captured in a preliminary way via a datatype 
property hasUnitsOfMeasure with domain ValueType and range string.

This issue is how to incorporate units of measure in general?

A possible immediate next step is to set the range of hasUnitsOfMeasure to 
rdfs:Resource, so a URI can be indicated.

Good description of the issue of modeling units of measure in general and the 
MUO ontology in particular. Also many links therein.

I'm having trouble seeing where this ties into the ontology - it could be used 
in many places (tolerances, ranges, as well as process outputs). Definitely 
agree that it should use an external UOM resource.
