Re: ISSUE-88 (md5): Ontology header request, optional md5 checksum of ontology

Might. My understanding is that not all servers implement providing  
accurate information about when a resource has changed, and given the  
perceived value of performance in this area, thought it might be  
useful to have a mechanism more under user control.

However, this should be considered a soft request, and I'm not  
terribly attached to it.
