Hi,
RFC 1630 is from 1994. In "Universal Resource Identifiers -- Axioms
of Web Architecture" Tim Berners-Lee wrote in 1996: "An object is 'on
the web' if it has a URI" (as only one example of many). Going on
with resource fun: The web is - again: as far as I know - part of the
internet, and a resource is by definition something having a URI;
ergo: simply by definition resources are always objects on the
internet. If we use resources, we - by definition - confine ourselves
to objects on the internet, and life is easy ;-)
There are examples of resources like this: "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), ..." by Roy Fielding in 2000. Some years ago on xml-dev
someone gave as an example of a resource: a beach with e.g. pictures
published as web-pages as representations of this resource. If I, the
current mailinglist contributor, had an URI, I would be a resource
and I would be "on the web" (it would be okay for me); e.g. my resume
and a picture of me would be representations of me as a resource.
This is _not_ meant as being uploaded to the web as in science fiction.
Guess, who said this: A resource is something like a Platonic idea.
Well, I'm no follower of Plato.
There are a lot of ... ahem ... definitions and explanations in
various publications by various authors and even by the W3C. If
someone insists (and gives really good reasons;-), I can deliver a
lot of evidence. But it wouldn't be worth the energy - so please
don't insist ;-). I don't care about those definitions any more - and
I can do my work very well.
Many of the resources in my work are non-electronic, e.g. persons,
organisations, equipment. The resources got URIs. The resources (or,
if you like: the representations of them) are accessible in a
RESTafarian way. This makes life easy. It's my experience only, of
course.
greetings
Klaus
