RE: [closed] williams-01, What is a node in an RDF graph?


Apologies for the delay in responding...

I have taken a look at the wording in [1] which appears to be the WGs
resolution referenced from [2] (the full reference to [1] seems absent from

The proposal at [1] does address my comment. 

I do have a question about the second paragraph of section 3.1:

 " A URI reference or literal used as a node identifies what that node 
   represents.  A URI reference used as a predicate identifies the 
   relationship between the nodes it connects.  A predicate URI reference
   also be a node in the graph."

Given the first sentence, does a predicate identify a relationship between
the connected graph nodes (which is what the 2nd sentence says), or between
the things that the connected nodes represent?

suggesting that "Nodes in an RDF are ... labelled with a URI Reference 
...".   We recognize that the terminology used has been inconsistent, and 
have resolved:

to revise the terminology consistently in a different way to that you 
suggest, viz. that URI References *are* nodes in an RDF graph, in line with 
the terminology articulated by Pat Hayes [1].


(I also note that the description of abstract graph syntax in section 6 of 
Concepts is
already consistent with this terminology.)

Can you please respond to <> indicating whether this 
response is satisfactory.  Thank you.
