Markus,
I agree that we need to keep the rules for
the XRI specs (purely technical) separate from the policy of any XRI provider
such as the XDI.org GRS (Global Registry Service).
However see the email I just sent for an
example of where the CanonicalID value for a GRS-registered i-name might in
fact change (from an https URI to an i-number). I admit that this use case is
probably a very edge case, and would likely be very rare.
In any case, GRS policy is discussed in
another forum – the XDI.org GSS (Global Services Specifications) mailing list
at http://www.xdi.org/mailing-list-gss-comment.html.

Subject: Re: [xri] CID changes in
wd11
Hey Les,
You all know the GRS 1000 times better than me, but here's an idea..
Maybe it would make sense to differentiate between XRI in general and i-names /
i-numbers in particular. We could say that
1) for XRI in general, CanonicalIDs are optional and can be hierarchical or
non-hierarchical, persistent or non-persistent, editable, whatever the user
wants...
whereas
2) for i-names, CanonicalIDs (i-numbers) are required and will not change once
the i-name has been registered.
Just a thought..

Hi
all –
After
reviewing the latest wd11 I have one major concern. This version allows a
CID to be changed after it is already set. I believe that this is a
big mistake. The CID is the persistent identifier for the queried
XRD. We need to ensure that once an XRD has a CID that that CID
identifies that XRD forever.
I
have always thought of the CID as a primary key to the global database we have
created with XRI resolution. Client applications have been and are being
written that depend on the value of this primary key for the mapping of an
identity described by an XRDS to their internal account structure. If we
allow this primary key to be changed we have caused a major data integrity
problem.
I
propose that the definition of CID not only revert back to the WD10 definition
but we also more strongly codify that a CID once set should never be
changed.
Thanks
Les
