The main problem I had with rwhois, way back when I ran rwhois, was that
the software would crash after a few weeks and since nothing noticeable
broke, I wouldn't realize it for a few months. Even if the software is now
rock solid, something on the server hosting it will break. It's just not a
first class element of the system.

On the other hand, SWIP is push-style database replication involving
mismatched and custom pieces of software plus manual submissions. The
probability of data synchronization problems approaches 1.

RDAP at least operates as an HTTP web app that can presumably be managed
the same way you maintain availability of your other web servers.

In the far future, I think ARIN should support RDAP. Period. Getting from
here to there in the intermediate term is another matter.

Not necessary. If changes are happening in enough bulk for that to be
needful, there's a programmer who needs a spanking.

On the other hand, if it's not available now then there should be a
facility for a registrant to **bulk-download** all their SWIP entries at
once for comparison with their local database. Otherwise data
synchronization requires a nasty dance.

If you keep rwhois then yes, of course. Caveat that by "automate" I mean
publish the referral in a machine-readable form in the rwhois response,
expect rwhois client software to follow it and make sure your own rwhois
clients (e.g. on your web site) follow it. Last I checked (which was a very
long time ago) ARIN did this brokenly: published both the referral and
contradictory SWIP data which really confused things.

No. JSON over HTTP is easy enough to work with and writing appropriate
interface modules should be the responsibility of the folks vending IPAM

On the other hand, curl --head http://rdap.org/ip/ lands at
http://whois.arin.net/rest/ip/ which does not output RDAP
formatted results (XML != JSON), so there's some work to be done on ARIN's
side just to report RDAP correctly with ARIN's own data.
