[db-wg] Proposal to remove "referral-by" attribute in "mntner" object or make it optional

Job and Denis,


Thank you very much for your comments and explanations! Just for sake of interest, what does the "stamp of approval" mean in context of RIPE database, i.e. who(and how) needs to approve such proposals?



WBR,

Dear Job and Martin

I am sure this point was also raised by Engin at a RIPE Meeting. But
there was no reaction either for or against. The RIPE NCC has proposed a
number of such cleanups in the RIPE Database syntax, business rules and
data over the years. But unless we get a stamp of approval we cannot
move forward with them.

A quick history of the "referral-by:". When version 3 of the RIPE
Database software was released in 2001 it was not possible for users to
create their own MNTNER objects. You had to contact ripe-dbm and ask for
one and justify why you needed 'another' MNTNER object. So only the RIPE
NCC created MNTNER objects. That is why the documentation said the value
of "referral-by:" had to be set to 'ripe-dbm-mnt' and could not be
changed. In general RFC2725 defined it as a chain of trust where any
existing MNTNER could create another one and be referred from it.

At some point the community decided asking ripe-dbm to create new MNTNER
objects was over bureaucratic and not necessary. So it was opened up to
allow anyone to create a MNTNER object, without any verification,
validation or accountability. This is the situation we have now where a
MNTNER is an anonymous box holding credentials of unknown and
un-identifiable people. These are the people who maintain data in the
RIPE Database. There was a cost to removing the bureaucracy.

As Engin pointed out, there was never any functionality implemented
based on the "referral-by:" attribute. When we allowed anyone to create
their own MNTNER we dropped the restriction on the value and changes to
the value. The recommendation was to make it self-referencing. This was
the easiest way to explain to new users what to put for the value. But
it still confuses users today and if the community agrees it would be a
good move to deprecate it, this would help a lot of people to understand
the database.

When we set up AFRINIC's database in 2005, we dropped the "referral-by:"
in their implementation of the whois software.

As there is no usage or dependency on this attribute at all, we can
deprecate it from the syntax and mass update all MNTNER objects to
remove it very easily.

If you wish to consider updating RFC2725 and RFC2622 (and later
versions) bear in mind this is not the only deviation from the RFCs in
the RIPE Database implementation. In fact from the start in 2001, the
RIPE Database software was never strictly compliant with the RFCs. We
used to say it conformed to RIPE RPSL, which was derived from the RFCs.
To bring the RFCs into line with practical reality would be quite a
task. Especially as the RIPE Database is a routing, reverse delegation
and Internet number registry. 'RPSL' was adapted to make it work for all
elements of the database.

I hope this explains where we are with "referral-by:". If you wish to
proceed with changing this, you may wish to take another look at some of
the other changes we suggested over the years that also never achieved
any consensus. Some of those suggestions are still applicable now and
would help to simplify aspects of the database and it's usage.
