Why do you feel that long names are somehow a bad thing?

If you feel compelled to use short names and are worried about short  
names being less meaningful to human readers, you can always add a  
longer description via rdfs:comment or dc:description.

For example:

	foo:SDIAccess rdfs:comment "Software Desktop Internet Access"
	foo:SDMVideo rdfs:comment "Software Desktop Multimedia Video"

As a side note,  I might suggest that you use upper-cased names for  
classes, and lower-case names for properties. That seems to be a  
fairly common convention.

My two cents,
Brian Manley
