Not sure, but related example that helped with FOAF:

Consider two zero-byte files, written by different tools and users on 
different days. They have the same sha1. This was helpful when thinking 
through some of the difficulties with saying that foaf:sha1 was 
OWL:InverseFunctionalProperty, and the different notions of document 
hidden inside the foaf:Document class.
