<Quote1>
Let's suppose that units-of-measure are represented as properties, e.g,
<River id="Yangtze">
<length>
<kilometer>6300</kilometer>
</length>
</River>
</Quote1>
My personal preference and style of representing this would be to
represent the unit of measure as an attribute of "length", because it
really does modify/describe/act as a property of the length:
<River id="Yangtze">
<length UOM="Km">6300</length>
</River>
<Quote2>
Do you have any suggestions on how to syntactically represent this
relationship statement?
</Quote2>
How about OWL?
Kind Regards,
