- o Russ Hobby: rdhobby@ucdavis.edu
- o Erik Huizer: huizer@surfnet.nl
-
- Area Summary reported by Russ Hobby/UC Davis
-
- At the end of the Columbus meeting it was announced by the IAB that
- Brewster Kahle from Wais, Inc. will replace Russ Hobby as a co-Director
- of the Applications Area.
-
- Applications Area Directorate (APPLES)
-
- The Applications Area Directorate met for the first time at the Columbus
- IETF. The Directorate will help the Area Directors on architectural
- matters and reviews. Members of the Directorate are appointed by the
- Area Directors. Nominations can be made by the Application Area working
- group Chairs. The Directorate can be reached at <apples@surfnet.nl> and
- currently consists of the following individuals:
-
-
- o Ned Freed
- o John Klensin
- o Steve Kille
- o Christian Huitema
- o Russ Hobby
-
-
- The first task of the directorate is to produce a document on an email
- architecture. This document will be used as a basis for discussion on
- this topic in the Applications Area. After the document has evolved to
- a state of maximum consensus, working groups will be created to focus on
- specific issues indicated by the Architecture Document.
-
- The directorate also discussed the general problem of character sets and
- noted that they will be a recurring problem in many applications. The
- directorate will develop an initial plan for dealing with character sets
- in applications and start a working group to address this problem in
- detail.
-
- The directorate noted the increasing difficulty for working groups to
- make forward progress. This appears to be due to the increasing size
- and interest in the IETF and the Internet in general. More people, more
- discussions, more time. In the future, the Applications Area desires an
- initial draft document be written by interested parties before a working
- group is formed. While the final result of the working group may look
- nothing like the initial document, the initial document will provide
- focus for discussion.
-
- There are four working groups jointly chartered under the User Services
-
-
- 1
-
-
-
-
-
- Area and Applications Area. They are:
-
-
- o Integrated Directory Services (IDS)
- o Integration of Internet Information Resources (IIIR)
- o Uniform Resource Identifiers (URI)
- o Whois and Network Information Lookup Service (WNILS)
-
-
- For a report on these Working Groups see the User Services Area Report.
-
- There were two BOFs held that reside under the Network Management Area,
- but are strongly related to the Applications Area. They are:
-
-
- o Mail and Directory Management (MADMAN)
- o IFIP Electronic Mail Management (EMAILMGT)
-
- For a report on these BOFs see the Network Management Area Report.
-
- Conference Control BOF (CONFCTRL)
-
- Now that video, audio and shared applications are starting to flow over
- the network, there is a need for the setup and management of conference
- sessions. This BOF focused on various aspects of controlling
- distributed network conferences. Several people related their current
- work and plans were made for coordinating work through an IETF working
- group.
-
- Interactive Mail Access Protocol BOF (IMAP)
-
- The BOF discussed efforts to update and standardize IMAP. Mark Crispin
- has a new draft of IMAP that will be submitted as an Internet-Draft. A
- sample working group charter was reviewed.
-
- Internet Message Extensions Working Group (822EXT)
-
- The RFC822 Message Extensions Working Group met for two sessions to
- review and approve the revised MIME protocol for Draft Standard. With
- several clarifications and with the removal of several optional
- features, agreed to previously on the ietf-822 mailing list, MIME was so
- approved.
-
- The Working Group has completed its Charter as currently written and is
- ready to conclude. There is significant MIME related work which still
- needs to be addressed and for which new working groups should be formed.
- Among the work are MIME extensions such as the definition of a
- content-integrity-check and content-disposition body headers to add
- general functionality to MIME. There are expected to be a large number
- of new content-types defined, most of which should be developed in
- specific single-topic working groups.

- MHS-DS Working Group (MHSDS)
-
- The MHS-DS Working Group focused on its Long Bud pilot project at this
- IETF meeting. Since the last meeting, some basic infrastructure has
- been established for supporting X.400 routing via the Internet X.500
- directory service. By the next IETF, the Group plans to expand this
- infrastructure and generate some tools such that we can demonstrate that
- the pilot project is functional and that the directory is actually being
- used by some MTAs to support message routing. To achieve this goal,
- specific action items were assigned to Working Group members.
- Specifically, two important documents will be written and circulated,
- and specific individuals will begin implementing important software
- tools. The documents will clearly define the purpose of the pilot
- project, outline its short and long-term goals, specify its relationship
- to the existing Internet X.400 community, and indicate how to
- participate in the pilot. The tools will facilitate the integration of
- the pilot with the existing Internet X.400 infrastructure.
-
- In addition to working on issues relating to the Long Bud pilot project,
- we assigned action items for progressing three Internet-Drafts as RFCs.
- In addition, one or two minor technical issues were resolved which will
- be reflected in the next revision of the Internet-Drafts.
-
- MIME-MHS Interworking Working Group (MIMEMHS)
-
- There are three draft RFCs in progress:
-
-
- 1. Mapping between X.400 and RFC822 Message Bodies.
- 2. Equivalences between 1988 X.400 and RFC822 Message Bodies.
- 3. HARPOON (Rules for downgrading messages from X.400/88 to X.400/84
- when MIME content-types are present).
-
-
- The first two have been stable for some time with no outstanding issues.
- The third (HARPOON) had some open issues and, until now, had never been
- discussed at an IETF meeting.
-
- During the meeting, the HARPOON proposal was presented, the issues were
- resolved, and it was agreed that all three documents would be forwarded
- to the IESG for approval as Proposed Standards.
-
- Minimal OSI Upper-Layers Working Group (THINOSI)
-
- The THINOSI Working Group met for the first time as a working group.
- Nearly all the time was spent reviewing the first draft of the
- ``bytestream cookbook''. Various changes were agreed upon, generally
- applying a principle of keeping things simple (and thin) for this first
- case, but ensuring interworking with ``full'' OSI implementations would
- be feasible. It will be highly desirable to achieve alignment with the
- ``minimal OSI'' profile being developed in OIW and EWOS. Identifying the
- range of applications to be supported is central to achieving this
-

-
-
-
-
-
- alignment - this should include at least DAP and X.400 P& if at all
- possible.
-
- Office Document Architecture Working Group (ODA)
-
- Over 1992 an international profile FOD26 was being approved. An
- industrial consortium was preparing an ODA toolkit which becomes
- available 2Q 1993. Pending the availability of this toolkit and the new
- profile, there has been little availability of new ODA implementations,
- though this will change during the third quarter of 1993.
-
- The Working Group had previously expressed interest only in piloting
- with real products. In view of their non-availability at present, there
- was little interest in the Group.
-
- It is recommended that the Working Group conclude. If there is further
- interest when products become available it can be revived, though this
- is unlikely to happen before November 1993.
-
- OSI Directory Services Working Group (OSIDS)
-
-
- o The Charter was discussed and several work items were defined.
- o There is strong consensus on the need for continuation of this
- Group.
- o Volunteers for editing papers are hard to find.
- o Schema management issue is still not resolved. This remains a
- major worry.
- o A new approach to presenting Quality of data in the Directory was
- discussed. It will be put on paper and aligned with earlier ideas
- of the Group.
- o Representation of registration, IP-addressing and Network
- Information was discussed. A series of Internet-Drafts will be
- produced on this issue.
- o Representation of documents and related information in the
- Directory was discussed based on four draft inputs.
-
-
- TELNET Working Group (TELNET)
-
- The Working Group continued work on the Environment Option,
- Authentication and Encryption.
-
- HP's Telnet MPX proposal for session multiplexing was discussed. Most
- people were impressed with the results but felt that, in general,
- session multiplexing did not belong in the Telnet layer. Perhaps this
- should be addressed as a TCP extension. In the meantime, the Working
- Group suggested that HP submit the protocol to be an Experimental RFC.
-
- There was enthusiastic discussion by a group of people who want to work
- on improving TN3270 to better match the current SNA environment. The
- TELNET Working Group felt that the TN3270 work would be outside the
-

-
-
-
-
-
- scope of their Group and work should be done as a separate working
- group.
-
- X.400 Operations Working Group (X400OPS)
-
-
- o Finalized Documents:
-
- - Requirements for participation in the GO-MHS Community for
- Informational RFC.
- - Routing coordination for X.400 services as Experimental
- Standard.
- - Evaluation of ADMDs as Informational RFC.
- - Assertion of the ADMD=IMX for Proposed Standard.
- - X.400 use of extended character sets for Proposed Standard.
-
-
- o Work Left To Do:
-
- - Automatic email distribution of tables.
- - X.400 - RFC822 mapping authorities.
