Yes, in "Resource Conflation" lingo. No, in reality. A URI is an Identifier. Remember it stands for: Uniform Resource Identifier. It should actually be: Universal Object Identifier or Universal Entity Identifier or Uniform Object Identifier or Uniform Entity Identifier. URIs Identify "Entities" or "Things". They can identify anything we can imagine. A Resource is a kind of "Thing" that has physical manifestation in a specific realm. Yes, we are "Resources", "Documents", "Widgets", but not in the Web Realm. You are conflating because Web != Real World. Thus, saying everything is a "Resource", when the rest of the world knows that everything is an "Entity" or "Thing" or "Object" is conflation that leads to utter incomprehension. How do you think Object based systems work? How do you think Object Oriented Database work? How do you think Object Relational Databases work? How do you think Relational Databases work? How do computers work? Is an Address the only way we use a Pointer? Do you seriously think that the ubiquity of an HTTP network, where physical resources represent Documents (e.g. HTML, RDF, XML etc..), warrants such overreach and disregard for the past re. computer technology continuum? "Resource" conflation days are numbered. Its usage and acceptence is inherently inversely related to Linked Data concept comprehension. Remember my statement above. Same applies to RDF = Linked Data, conflation. >> - it's not a document > I think it is It cannot be! It resolves to a Document. Without Documents how can one perceive anything across any medium? >> - it's not an rdf document > I think it is It resolves to a Document Type where the Content is expressed in on of the RDF markup syntaxes. > >> - it's not a toucan > Agree. That text is not a toucan. > > Yes, but for a different reason. The Toucan is the Referent of the URI. This is how its always been, if it wasn't you wouldn't be reading this mail via a computer system that uses pointers to create references that enables us walk data structures, programmatically.
