I'm gratified to see explicit acknowledgment of using URIs as pointers  
to dictionary entries, which of course will change over time and  
appropriately so. (But with the great additional feature that each  
change can be versioned, so tracking word meanings over time is a snap!)

Or, "B) Not change - I am grateful that the meaning of this concept  
URI will always be consistent, so that I can be unambiguous in  
referring to it, and that there is a new concept URI I can use to  
refer to the new and better term, so everyone will recognize I am  
using the new meaning."  Depending on the personality of the user....

Not sure I follow you.  You own the URIs in that owning the domain  
lets you 'control the authority' and you can put whatever you want  
there.  As a dictionary provider, of course, you are at the whim of  
the actual usage for these terms -- is that what you mean?  That would  
be true of any knowledge provision enterprise, of course.

Yes, especially for providers who are offering general term storage  
services.  We've had to work through whether, and how, to support both  
choices (A) and (B) simultaneously while still maintaining fidelity to  
semantic web assumptions. Pretty interesting indeed!
