Dear Drew,

SKOS indeed seems one right tool to use in your scenario.
Of course the exceptions that you mention make much sense. But do not forget that Semantic Web techniques allow you to specialize SKOS constructs (such as skos:related and skos:definition or skos:note) as you see fit!

For example:
your-namespace:expression rdfs:subPropertyOf skos:note .

This way, you can represent specialized data in your application, but it remains compatible with more general SKOS tool.

Best,

Antoine
