Maybe, but I'm not aware of the full context, so ignore me if this doesn't make 

file:// URIs are interpreted with respect to a specific host environment 
(commonly localhost, but can be named).  While it's possible to separately a 
denotation, I think it could prove tricky to use this in a global reasoning 

So, if the example is strictly local-use then file://... might be OK, but if the 
idea is to create provenance that can be shipped across the web I'd suggest 
avoiding file:// URIs.

(This reminds me that there's a proposal for a ni: URI scheme that identifies by 
way of cryptographic hash, which might be useful for some aspects of provenance
