Instead of starting out from a position that we *must* have two different resources, can we instead highlight to people the *benefits* of having different identifiers?But you don't have two different resources. Please correct me if I am reading you inaccurately here, but are you saying that: http://dbpedia.org/resource/Linked Data and http://dbpedia.org/page/Linked Data == two different resources? I see: 1. 2 URIs 2. a generic URI (serving as a Name) and a purpose specific URI called a URL that serves as a data access address -- still two identifiers albeit split by function .RFC3983: "A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource."
Yes, I agree with that.
2 URIs, therefore 2 resources.
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.
