Hi Ulrich, Notifications is becoming a complex issue in itself now. In the case you mentioned below, the notify: in the mntner is only used if the mntner object itself is modified. There is a close relationship now between the mnt-nfy: and the proposed ref-nfy:, but they are not the same thing. If you successfully modify a person object by adding a mntner into a mnt-by: then the mnt-nfy: would be notified about a successful modification and also the ref-nfy: will be notified because the mntner has been referenced. However, consider the case where an inetnum object is modified by adding a mntner into a mnt-lower:. In this case the ref-nfy: will be notified because the mntner has been referenced. But the mnt-nfy: of the referenced mntner will NOT be notified in this case. The mnt-nfy: of the mntner in the inetnum's mnt-by: will also be notified of a successful modification, but this may not be the same mntner as the one referenced in the mnt-lower:. I think we will need to write a small document explaining all the notification rules. We need to think carefully about who is notified and when and we wrote the code to apply these rules. So I think it will be very confusing to a new user of the database. cheers denis Ulrich Kiermayr <ulrich.kiermayr@univie.ac.at> writes: * Hi Denis, * * > [snip] * > * > It may be a bit of an overkill to add mnt-ref: to the mntner: as in * > most cases people would probably make it refer to itself, although it * > would be consistent.
