RE: [metaDataInURI-31]: Initial draft finding for public review/ comme nt.

The problem  of identity (system assigned identifier) and 
identification is what **a system** makes of it.   The W3C 
can assert that within the system over which it has 
authoritative jurisdiction, a mailto is a valid identifier 
for a user of that system.  As soon as that identifier 
is used in a different systemic context (eg, an eBay 
screen name as an identifier for a perpetrator of 
fraud), then the means and proof of the process of 
identification is important and will be in question. 

It is insufficient to state a label is an identifier 
unless the identification process is named or the 
means of association is specified (eg, this can 
be an identifier because of these properties within 
this system).

The assertion of the identification process cannot 
be overlooked nor can its system scoping properties.  
An identifier is a labeled unique instance of some 
syntax specification without these.

I agree with Roy one should not confuse these, but 
one must understand their coupling and that one 
does not exist without the other.

The eBay example is not facetious.  It is a real 
world example.  Because of that, there is high 
interest in the results of this finding.

1.  What are the properties of an identifier in 
the web system (say architecture)?

2.  How can these be associated to an identification 

3.  Is the web architecture silent about uses of 
a web identifier outside the scope of this architecture?
(IOW, if you ever have to give an advisory to a legal 
process, what would you say?)

Item three does not have to be answered to get this worked 
in the architecture, but some W3C authority should be 
preparing to answer it on behalf of members such as eBay.

I'd have to disagree with it, for the reasons I gave.  I agree with
what Roy just said too.

FWIW, my FOAF ( is authoritative;

  <foaf:Person rdf:about="">

The mailto URI was just an example.
