Editor's Note: Minutes received 8/14 CURRENT_MEETING_REPORT_ Reported by Steve Thompson/ODS Minutes of the MIME-MHS Interworking Working Group (MIMEMHS) There have been two papers produced since the last meeting: 1. X.400/MIME body equivalence Harald Tveit Alvestrand, Steven Thompson 2. Mapping between X.400 and RFC-822 Message Bodies Harald Alvestrand et al. Several mappings have been defined, and for those without a clear X.400(88) equivalent there is a trapdoor/catchall External bodypart defined in X.400: EBP-mime-body-part. In the other direction the trapdoor in MIME is a new Mime subtype: application/x400-bp The session consisted mostly of a presentation by S. Thompson and H. Alvestrand on the material, since the papers were released shortly before the IETF. The discussion raised the following issues for resolution: o Registration - How to get vendors to register OIDs as well as the equivalent MIME subtype with the IANA. Thompson is working with the EMA (Electronic Mail Association) and Jon Postel on this issue. - How to manage IANA registration of different versions of BPs like WP5.0 and WP5.1. - Should there be automatic OID assignments for MIME Subtypes? o '84 X.400 Support. This subject got the most discussion, by far. - Should the RFC address '84 explicitly or should 88-84 downgrading be enhanced to handle it. - Simplest case single BP IA5 - Should this be a MIME document or just an RFC822 message. - T.61 strings in header vs RFC 1327 needs resolving - Three-party mail issue (mime-X.400(88)-X.400(84)). 1 o The documents need appendices with OIDs defined o Security: viruses will be gatewayed too, not solved in this paper. o Criticality of header extensions must be defined. o Conformance: Is there a different level of support for gateway's vs. User Agents for the newly defined X.400 and MIME constructs? Issues will be resolved by E-mail in the next couple of months. Both documents will be forwarded as proposed standard RFCs.
