Re: Cool URIs for the Semantic Web

Hi Leo,

In my understanding you're creating an overview of several methodology so
the idea is a fair comparison between approaches. If that is the purpose i
object that your treatment of the "other" methods is way too biased, as a
result of you chosing basic design principles which are arguable at least.

I personally see absolutely nothing wrong with identifiers such as
ISBN:123-123-1233 or MD5: 998798798 or  TAG:
giovanni.tummarello@deri.org/mycat/CHICCA.

Why should i better use an amazon page for a book than the simple ISBN (then
you chose you preferred store? Why sohuld i use a URL to indicate me, then i
might loose the DNS domain for some reasona and have a spammer putting
immoral binaries as a resolution of my "identifier".

In fact i see many obvious advantages of these, in terms of stability,
neutrality, maintainance, etc.
but in SOME CASES. In some others its ok to mix identifiers with
reppresentations.

there is, in my view, not a single way to do identifier but one has to see
per domain and the choices are more than what are written in that document.

To conclude.. what about making it a wiki page? If not, what about making it
a blog post so there can be hints of counterargument in a world readable
way? :-)

Related issue: There might be some space for spontaneous
discussions/lightening talks at the W3C workshop I3 Identity, Identifiers,
Identification  http://okkam.dit.unitn.it/i3/ , if anyone would like to book
a space for it please let me know, i cant guarantee at this time (the
program has not been finalized) but we'll likely reserve some space about it
