Re: Named Graph Serialisation (add to publishing linked data document?)

Hi Giovani,

within the Linked Data tutorial we wanted to focus on Linked Data 
only.

Therefore, we did not write anything about dumps, SPARQL endoints, 
RDFa, GRDDL, microformats and alike.
All these things are important, but the topic of our tutorial was 
Linked Data.

I also clearly appriciate your work on trying to bring all this 
different publication forms together.

Cheers

Chris

Chris i think this issue is VERY important for publishing linked data
in general.

Would it make sense that you add a chapter to your publishing linked
data document called "providing a dump" and list these alternatives?
(and others that might come?)
If it does, please do :-)

i think spiders can then find out by themselves what format it is.. as
long as there is somehow a list of those "generally recognized"

thanks
Giovanni
