All, A proposal for an accreditation mechanism is attached. This proposal is based on the earlier RBL scheme proposed by Vixie, and designed to be compatible with CallerID. I will submit as an ID later on today. Basically the scheme returns an A record in response to a lookup. So in order for example.com to announce that it is accredited by the class3 service of verisign the SPF or CallerID record would contain the tripple: "accreditation" "class3.verisign.com""DNS-A" I.e. this is an accreditation property, the accreditor service is at class3.verisign.com, the protocol is a DNS A record lookup. We can conflate the "accreditation" and "DNS-A" components, but that is a bad idea, the A record convention is pretty limiting, there are only 24 bits worth of data that can be returned. It would be useful to be able to extend to use of other protocol records such as NAPTR and SRV. Some folk inside VeriSign suggested that we use the convention that an unlisted domain just returns domain does not exist. I believe that we should have some facility here for a description of the accreditation service. This is because the receiver has to arrive at an evaluation of the accreditation service before the information can converge. The ability to use learning systems is very attractive here. Telling the learning system basic information about the format of the data is pretty useful, what is the basis that the info was collected on, is the data bit field formatted or in some other form? I provide the start of a description language here but on second thoughts the best approach here would be to write the data structure in XML, stick it up on a web site and put the URL in the DNS. The format is not a big priority for me at the moment since it only really affects the accreditation services and the filter writers. I don't think that either community will be particularly large (10 to 20 at most). It is not something we need to make a priority when we are using our limited standards track bandwidth. Phill
