Thoses protocol could certainly have been utilized and the community did not ignore them. In fact the pro's and con's were vigoursly debated at NANOG and IETF. In the end the community decided the best way to go was RFC 2769. > The querying > mechanism for the IRRd is not RFC documented and returns 'F' when errors > occur.

Just in case you were not aware, we do have an on-line IRRd users manual at www.irrd.net. We do our best to keep the manual updated and it does provide detailed information for those who wish to use it. IRRd started out as a machine interface so was born the 'F', 'D', 'C', etc.. return codes. You will find a section in the manual which explains the return codes. The ripewhois interface (designed for humans, mostly) does return english sentences. I agree with you that the internal source code documentation is sparse. To address this issue (and others) we are currrently conducting a full code review and clean up which should help to address this problem. > > The protocol lets you auto discover new registries, and of course you > > can choose what to do with the newly discovered registries.

Merit is already taking steps to help coordinate the distributed DB effort. We have a listing of remote registries with associated information at http://www.radb.net/docs/list.html. And when we impletment RFC 2726 we will have 'repository' objects corresponding to each remote DB that we mirror. This information will give the community a DB source to discover new DB's and to utilize them (or not) as they wish. We view our effort as a first step in assisting the community going forward. It remains to be seen what will end up being the best method to provide this information. > It would not be (as) difficult to define an rwhois schema that has the > desired functionality plus a protocol extension or two to account for any > extended behavior, such as caching. > Please don't take this as bashing on the authors of the aforementioned > tools.
