Dear Richard,

It requires a sort of datatype or encoding.

Assume unit = "ft&inches"
               value = <3,6>

would that make sense?

In the xsd datatypes everything is in the value already.
The XSD datatypes all resolve to single values, so don't give a clear steer from them as to how to deal with the 'multiple units' issue.

I can see what you're saying as regards a 'complex' datatype, but I can't find examples on the Web of how the value would actually be encoded as an RDF value which software agents could do anything useful with. 

The best I have come up with is this document from 2002:


which has some heavy hitters associated with it.  Is this the sort of approach you are proposing?

A slightly more complex example would be a geographical coordinate expressed as latitude and longitude (both expressed as degrees, minutes and seconds).
