Then why don't you use the same simple scheme with POST?

Alternatively, I'd consider using GET and supporting a second form of  
query with parameters s, p, and o_hash. The first two are like  
before, the third one is, say, an MD5 hash of the literal (including  
its datatype or language tag). To reconstruct the right object on the  
server side, you'd have to do a find(s, p, ANY), calculate the hashes  
for each result object, and check if one is equal to the given  
o_hash. This should work with existing triple stores (like RAP's DB  
model) and should be reasonably fast because no more than a handful  
of hashes need to be calculated per request.

All other solutions I can think of would be a lot more work or much  
slower.
