Hi Denis,
I support the idea of having empty AS-SETs deleted automatically and keeping
only AS-NULL in the DB.
@Edward Shryane question to the DB team: would it be possible to have some
functionality in the LIR portal that converts the short-named AS-SETs to the
hierarchical ones with a click of a button? That would help people transition
much easier and faster to the hierarchical AS-SETs. Perhaps a button that can
be triggered by user and 1) creates a new hierarchical AS-SET 2) copies all
elements from old AS-SET to the new one 3) Deletes the old AS-SET 4) Updates
the corresponding import/export rules.
Kind Regards
Stavros

One empty set is the same as any other empty set. We only need one
clearly defined and easily recognisable empty set and we have that,
AS-NULL. If I create an empty set, AS-WALKER it doesn't do anything
that AS-NULL can't do. But AS-WALKER isn't instantly recognisable as
an empty set. You have to query it to see that. If we have 100 empty
sets in the database, including AS-NULL, that are all being used for
valid reasons, 99 of them are redundant, duplicated objects and should
be deleted...unless someone can tell me the value of a duplicated
empty set.
