Is it better  to label these relationships with the terms 'broader'   
and 'narrower' whilst defining them with the semantics of 'related'?  
Wouldn't it be better to use the standard labels to denote the  
standard semantics, and use a special label, disjoint from broader,  
for the non-hierarchical hierarchies?

The SKOS Core Guide[1] originally aligned itself with Z39.19/BS8723;   
I feel it's a mistake to abandon the standard semantics without also  
abandoning the standard labels. The Library of Congress adopted the BT/ 
NT labels for its syndetic relationships  in the LCSH, without fixing  
the semantics; this has not proven helpful :-)


Broader/Narrower Relationships

To assert that one concept is broader in meaning (i.e. more general)  
than another, where the scope (meaning) of one falls completely within  
the scope of the other, use the skos:broader property. To assert the  
inverse, that one concept is narrower in meaning (i.e. more specific)  
than another, use the skos:narrower property.
[...]
The properties skos:broader and skos:narrower are transitive properties.

See also section on hierarchies in BS8723.
