[db-wg] Role of RIPE NCC in geofeed, abuse-c checks, etc

Hi,

I just wanted to clarify my stance on validation a bit more.

I am totally against trying to validate the data itself, that is not
what the NCC is supposed to do.
Validating the format of the CSV might be okay but honestly anything
beyond validating that it is not a 404 not found is a bit too much in
my opinion.

I also agree with Leo's points with regards to fixing the data, I
believe that the data publishers have a pretty strong incentive to
have the data be accurate.
And as Leo also mentions, the tech-c and/or admin-c contacts are also
published so finding a reporting mechanism for issues would not be
very difficult.

And with regards to misformatted data, yeah I would probably just
ignore that entry if I was writing a parser and log the error and
report it to an engineer who can then forward it to the admin contact
if they determine it to be a real issue.

In order to not infinitely delay this, I feel like while it shouldn't
be rushed, I am not sure how realistic this issue would be and how
much harm it would cause to anyone.

Also, changing how much validation is done could be changed in the
future if it is shown to be an actual real world problem.
