Yes, I agree with that.

I disagree with your interpretation though.

Identifiers are names / handles. Thus, you have Names that resolve to 
actual data albeit via different levels of indirection.

http://dbpedia.org/resource/Linked_Data and 
http://dbpedia.org/page/Linked_Data are routes to different 
representations of the same data. /resource/ (handle or name) is an 
indirect access route while /page/ is direct (address i.e., a location 
name) albeit with representation specificity i.e., HTML in the case of 
DBpedia.

I am very happy that we've been able to narrow our differing views to 
something very concrete. Ultimately, we are going to arrive at clarity, 
and that's all that matters to me, fundamentally.
