Hi Bjoern,

Thanks for sending comments to the DAWG.

Some questions for you so we get a better idea of your thinking:

o Do you feel that this is something that should be part of a standard 
access protocol?

o How does it help you as a developer to have it as part of an RDF 
access protocol, rather than part of some other network protocol (e.g. 

o How would you see such a function being embedded in the protocol? For 
example, if a HTTP based protocol were to be adopted, would it be 
embedded in the headers?

Does anyone else feel that this it beyond our scope? This is already 
address in some network protocols. Perhaps as part of any HTTP based 
protocol we could bundle it in the header??

Good point, only UC 2.7 discussed this currently. I'll ask the DAWG for 
further comments on whether we need more use cases that address this 

Do we have a need to address more use cases to datatype support? Is it 
sufficient that we only have one use case that addresses this
