Re: Meaning of property "url"

Yeah, I think we just took a turn for the existential. This comes up a lot in ISNI discussions (are we our identifier?). Anyone read "True Names" by Vernor Vinge?

"Any information that can be named... e.g... a person..." There may be some philosophical issues there; is a person "information"?

Sure, an antelope in a zoo may be a document (http://pages.gseis.ucla.edu/faculty/maack/BrietPrePress.htm) but isn't this taking it a little far? ;)

Hi Michael,

(schema.org<http://schema.org>'s "url" property) means something very specific:
"this is the Web location of" _____ (where ______ is some network
addressable digital file).

That is what I thought, too. But the I wonder why:

"url" is a property of class "Thing" (instead of just class
"CreativeWork") there is no property "homepage" for class "Person" or
"website" for class "Organization"

The notion of a URI identifying a "file" is terribly antiquated. So many URIs identify resources that have representations (html) assembled on the fly as the result of queries to databases and whatnot. I prefer to think that url being a property of Thing was an intentional move, because the author chose to sidestep the
httpRange-14 issue, and let URLs identify any type of resource, as is the case in Roy Fielding's description of resource:

"""
The key abstraction of information in REST is a resource. Any information that can be named can be a resource: a document or image, a temporal service (e.g. "today's weather in Los Angeles"), a collection of other resources, a non-virtual object (e.g. a person), and so on. [1] """
