Subject: RE: [xri] Use of the word "synonym" in section 10
|
Les, Yes we agree that the term in used too
often. In my view, I’m trying to eliminate it its use outside of model
that clearly establishes its definition. And thus I find myself needing to be somewhat
pedantic in my response. > from your examples, IMHO
=steve.churchill and =steven.churchill and the CID > that goes with it are synonymous
because they are the same identity. These identifiers cannot be synonymous outside
of a model constituting the definition of synonymity and identity. For example,
three separate models were presented in my previous email to Markus. The
identifiers above may be synonyms in all, some, or none of these models. So I
disagree with you saying that “they are synonymous”. This has no
meaning to me outside you first establishing the model. > @ootao*steve is a reference that may
be the same person but no one can know that > for sure except you. It is just
a reference between two authorities. > I don’t really care if you want
to call a reference a synonym I just find that that term is used to often. In none of my examples did I say that
@ootao*steve was contained in the value of an xrd:Ref. If I we’re to establish
a reference to @ootao*steve, I would probably opt to use its CID in the xrd:Ref
element anyway. I think that what you are getting at here
is that the value contained in a Ref element could be thought of as a “synonym”
under some particular model of synonymity. Perhaps so, but if that is how the
Resolution Spec decides to employ the term, well, then that is quite
unfortunate, because it prevents or greatly discourages using the term where it
actually provides some real value (such as within the context of describing the
Canonical ID Verification model.) In the context that you suggest (and which
the Resolution Spec currently employs), the term only serves to confuse. ~ Steve From: Steven Churchill

the same XRD. I think that you are saying that a value of a CanonicalID is
synonymous with the value of LocalID is synonymous with the value of a Ref is
synonymous with the value of a Query given that the values show up in the same
XRD. This definition of “synonym” has no practical
value that I can see. On the other hand, the property of XRI identifier
synonymity is one of XRI Resolution’s most valuable features. I would
hate to “lose” the use of the term by associating it with your
meaning above. ~ Steve From: markus.sabadello@gmail.com

I
don't understand the use of the term "synonym" in section 10. In
English, if two words are synonyms, then they have the same (or roughly the
same) meaning. In the Identify field, if two identifiers are synonyms, then they
refer to the same identity. As
I try to express in my text for section 11, these concepts are dependent upon
the "model" (or "system") defining the notions of
synonymity and identity. In a Banking system, identifiers may include a
person's name(s) and account number. In that same model, identity may be defined as "the human
being person having a given SSN and DOB". (Don't get confused by the fact
that a SSN is also a type of identifier. That is incidental to the model. We
are talking here about establishing the definition of identity. Once that is done, then Steven
Churchill and Steve Churchill can be synonymous identifiers for the same
identity.) In the XRI Canonical ID Verification model, there is a clear notion
of synonymity and absolute identity. In any case, the model needs to be
formally defined before we can start referring to this thing or that thing as a
being a synonym. A synonym to what? Section
10 introduces the term synonym without establishing a model that defines either
synonymity or identity. As Gabe and others have correctly pointed out, XRI
supports many such models. What are synonyms within one model are not
necessarily synonyms within another model. It
is not helpful to use the term synonym outside a model defining how two identifiers
get mapped to the same identity. ~
