I appreciate you making this distinction.

as much can like an idea , that wont have much impact on its realism.

The [2] you mention is a great resource to start. From that page:

"A service that has no means of discovery (i.e. a link) or advertising
is "on" the Web but not
"in" the Web, under those terms.  It just happens to use a set of
protocols but it
is not part of a web.  So it should not be called a web service, just
an unlinked-to resource."

so 9 years after would you feel this very definition is any credible
or accepted? The man is saying that no explicit  link to a web service
from another web page = not a web service..

That reality says this is false (or would be considered false today by
anyone i care to talk to) .. i think the that extension to the
discussion in question is quite straightforward.

i agree of course, so here i am happy to clarify if needed

 i meant solely what i wrote, " I  dont think this is unrelated to the
attitude of dismissing real world reality checks and requests for

and if we read it for what it is i stand by it: You're often a
reviewer too. How many times do you see actual studies comparing LOD
based solutions against others? "let other people e.g. the industry
judge our value" is not something a scientific community should say,
but some sort of cult.

it should indeed be the tasks of researchers to write books and papers
that do go trough the boring hassle of serious reality based
comparisons vs  just descriptions of their own systems. When this
doesnt happen the result are quickly uninteresting which is then
captured in a conference rating.

but yes it is a different thread. I'd love to have a nice fruitful
discussion on this at some point.
