Re: [salud] Revised reply to Pearl Liang (IANA)

[[e-mail] (Dale R. Worley)]

[as an author]

Trying to close out the remaining work, I ran into the fact that I
haven't sent a reply to IANA yet.  This is a revised version, based on
Paul's observation that it would be wise for us to decide on the
registry structure ourselves.  I've incorporated a two-registry
structure, one for alert-categories and one for alert-identifiers.
Looking at the new structure when written down, I think it is
considerably clearer than a one-registry structure.

Please look it over to see if there is anything that is wrong or
unclear.

This has been revised to three actions:  adding a row to "Formal URN
Namespaces" and creating two new registries, as described below.

This is correct.

Two new registries are to be created, as described below.

> New URNs in the Alert URN Identifiers Registry are created through
> Standards Action as defined by RFC 5226.

That is not correct.  The process is more complex than that; the
details are in section 9.1 of the RFC:

   The policy for adding a new standard <alert-category> is 'Standards
   Action'.  The policy for adding <alert-identifiers>s or patterns of
   <alert-identifiers>s within a particular <alert-category> may differ
   for each <alert-category>and MUST be defined by the document defining
   the corresponding <alert-category>.

That is:  New "alert-categories" (items that do not contain a colon)
are created by Standards Action.  The policy for a new
"alert-identifier" (an item containing a colon) is set by the
alert-category that it starts with.  All existing alert-categories
specify the policy 'Standards Action' for adding alert-identifiers.
The registration policy for any alert-category will be stated in the
RFC that defines it, so the "Reference" column implicitly specifies
the registration policy for that alert-category.

After discussing this with the authors, we believe that the required
information can be best recorded with two registries, one named "Alert
URN alert-categories" for the items that are alert-categories (the
items without colons) and one named "Alert URN alert-identifiers" (the
items with colons).  Both registries will be under the protocol name
"Uniform Resource Names (URN)", and thus will be alongside "URN
Service Labels", not a sub-registry of it.

The two registries are connected by the fact that the registration
procedure for an alert-identifier is controlled by the corresponding
entry in the alert-category registry.  This is somewhat like the
"Range/Registration Procedures" table in the Sieve Extensions
registry.

The registries would look like this:

    Alert URN alert-categories

    Registration Procedure(s)
	Standards Action

    Reference
	[RFCxxxx]

    alert-category   Description           Reference   Registration Procedure(s)
					               for alert-identifiers
    --------------   -----------           ---------   -------------------------
    service          Specific telephony    [RFCxxxx]   Standards Action

                     other party to the

    [etc.]

and

    service:call-waiting                                              [RFCxxxx]
                      Call waiting was initiated at the other side
                      of the call
    [etc.]
    source:unclassified	                                              [RFCxxxx]
                      Unclassified ring/ringback rendering (default
	              value)
    source:internal   User at the other side of the call is internal  [RFCxxxx]
                      to the enterprise or PBX system
    [etc.]

The authors believe that a two-registry structure allows the
registration procedures to be specified more clearly.

The list of initial registrations in your e-mail is correct (allowing
for the irregular use of line breaks in the original e-mail).  The
alert-category entries are to be placed in one registry and the
alert-identifier entries are to be placed in the other registry.
