Yes. But no Linked Data browser I'm aware of applies 
owl:equivalentProperty assetions before rendering the data. (In fact, most 
do no reasoning at all.) I agree that, whatever our default display, 
it should include the appropriate mapping statements, either via an 
rdfs:seeAlso or similar link, or directly in the document.
