CID changes in wd11

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
