Apologies if you receive more than one copy of this. Jill IETF - Danvers: April 3rd - April 7th, 1995 ============================================ Trip Report: Jill Foster - Newcastle University, UK UK Mailbase Manager Introduction ============ The IETF (Internet Engineering Task Force) met in Danvers near Boston. The final number of attendees was around 800. The local hosts were FTP Inc and Steve Knowles headed the local host team. This was the first time the format did not include plenary technical sessions. There are now over 100 Working Groups (WGs) with around 70 of these meeting in Danvers, therefore there is an increasing difficulty in finding enough slots for them all and in avoiding overlaps. I found even more overlaps this year (ie parallel WG sessions of interest to me). The IETF started as normal with the new attendees session at 4pm on Sunday, followed at 6pm by registration and the reception. The programme itself started at 8am Monday morning with the WG chairs meeting and continued with WG sessions all week scheduled until 10pm each day. The WG chairs meeting (quite large in itself) discussed the ways of dealing with "disruptive" behaviour in WGs. There were two sessions during the week for new WG chairs on how to be an effective chair. (There is an RFC on Guidelines and Procedures for IETF Working Groups.) My main reasons for attending this IETF were to: o provide an informal liaison report on behalf of the TERENA Information Services and User Support Working Group [Terena is the Trans European Research and Education Networking Association] o join in the User Services and associated WG sessions. o chair the WG session on network training materials. The following informal report is in note form and deals mainly with the areas of User Support and Networked Information Retrieval. (It is shorter than my previous reports and contains fewer URLs due to a change in my own work roles. I no longer work for TERENA on a part time basis and my own "volunteer" effort is now committed elsewhere.) Whilst this report is as accurate as I can make it, it is naturally a personal account and may be inaccurate due to lack of background information or misinterpretation of what I heard. Corrections of fact are welcome, but any discussion of items contained here would be best directed to the appropriate mailing lists. Minutes of individual sessions are available via anonymous ftp from cnri.reston.va.us for example as html/html-minutes-95mar.txt or from the IETF Web server. Note that the charters of most working groups and other WG and IETF related information is also now on the web. URL: http://www.ietf.cnri.reston.va.us Note: in general I have not expanded acronyms as those readers involved in a particular topic should know them whilst those who aren't familiar with the acronyms should still be able to get a reasonable overview of the topic. Each section has a double underlined heading - to enable you to skip sections not of interest. USAC: User Services Area Council ================================ Chair: Joyce Reynolds - ISI Joyce Reynolds is chair of the IETF User Services Area (USV). She has a small group of 'advisers' known as the User Services Area Council. The main role of USAC is to advise on USV direction and to review proposed RFCs in the USV area. Joyce held an extended lunch meeting on the first day for the USAC members and Working Group chairs in the User Services area. This was a useful exchange of information at the start of the week on what was happening in the various WGs and any problems etc that we had as chairs. (Erik Huizer had started such meetings in the Applications area about a year or so ago and it was felt to be a very useful method of ensuring coherence between the WGs.) User Services Working Group =========================== Chair: Joyce Reynolds - ISI This is the umbrella group for the working groups within the User Services area. Several Working Groups (WGs) had recently closed leaving the following WGs in the USV area: IDS: Integrated Directory Services (joint with Applications area) IIIR: Integrated Internet Information Resources (joint with Applications area) URI: Uniform Resource Locator (joint with Applications area) ISN: Internet Schools Networking NISI: Network Information Services Infrastructure Trainmat: Network Training Materials RUN: Responsible Use of the Network SSH: Site Security Handbook (joint with Security area) and USWG: User Services Working Group (the umbrella group) The Arts and Humanities BOF met for the third time. They were to become a full WG in the near future. Interop: Joyce reported that there had been an IETF related session at Networld Interop 95, which had taken place the previous week in Las Vegas. Interop is a huge trade fair with 65,000 attendees. The various IETF Area Directors had each spoken about their area and the work being done. Attendance of this session had been disappointing. RIPE: Joyce attends the European RIPE meetings as a liaison member. She now reports on IETF USV WG issues to the RIPE plenary (rather than a RIPE WG on Network Information Discovery and User Support (NIDUS). This WG is effectively closed down. It looks to the results of the IETF WGs and TERENA ISUS (Information Services and User Support) WG. TERENA ISUS WG: I reported on the TERENA Information Services and User Support WG activities. The group had met just before the last IETF and had not yet met this year. TERENA was formed in October by the merger of the two European networking associations: RARE and EARN. TERENA is the Trans European Research and Education Networking Association. There were still problems following the merger resulting from a conflict of interests and culture and the fact that the members of the new association had widely differing needs. A satisfactory method of working together and developing (or not) a technical programme needs to be found before there is much progress on the technical side. The European Commission has a funding programme called Fourth Framework. This has one section, Telematics for Research, which has some 50Mecu (very approximately 50M dollars) of funding. TERENA has bid to provide a supporting role to the Telematics for Research part of the programme (project SCIMITAR). This would: o ensure that results of the programme were fed into the standards process by bringing them to the IETF o provide a user community (via the working groups) for the testing and validation of results o provide experts (via the working groups) to evaluate the results of the programme. In addition, members of the ISUS WG and others had put together a bid for a 5Mecu project called DESIRE. This was to: o build an information infrastructure (based on much of the work on whois++, URIs etc) o provide better support for the full range of multi-media information. (Fourth framework aims to move from text based to multi-media based communication and information services.) o provide support for information gateways. These are valued added services where information resources of interest to a particular subject area are collected (ie pointers to them) and selected (judgement on their quality and relevance). URCs are built and held for these resources (abstract, size, author etc) so that the user has meta-information that can be viewed prior to retrieving the resource itself. o training for selected user communities in the use of the new networked information discovery and retrieval tools developed as a result of the programme. The TERENA ISUS WG is similar to the IETF USV area. It has a range of Task Forces (like IETF WGs). Joyce and I have worked together to ensure liaison and to minimise overlap. Each ISUS TF has a home page with information about the charter, current documents, mailing list archives etc etc. (USV WGs are encouraged to do the same!) See: http://www.terena.nl/ USV-Web: Susan Calcari, Mark Kosters and Debbie Hamilton had been working on the USV Web pages. These had been moved from is.internic.net to rs.internic.net following the "exit" of General Atomic from the InterNIC. The pointer given was (may move): http://rs.internic.net/usv-web.html Susan Calcari would like comments. (scal@cts.com) Web versions of FYI RFCs: Janet Marcisak (FTP Inc) has completed marking up ALL of the FYI RFCs (including the NIR report)! These will be moved to ISI with the other RFCs. USV-TV: The Trainmat WG had wanted to investigate using the MBONE to deliver network training. It was suggested that USV people could do some preliminary testing to gain some experience and then to use it to spread the word about USV. Joyce reported that there has been no real progress in getting permission to use the MBONE. Mark Prior (Trainmat co-chair) had pointed out that if the MBONE could be used to broadcast a Rolling Stone's concert... Mailing list: us-wg@nic.near.net To join, mail to: us-wg-request@nic.near.net NISI - Networked Information Services Infrastructure WG ======================================================= Chair: April Marine (NASA) This group is concerned with co-ordinating NICs (network information centres) and improving the service they provide. April was unable to attend, so the group did not meet in Danvers. It is planned to have one more meeting to complete work in progress at the next IETF. Current draft: ftp://naic.nasa.gov/files/april-drafts/nic-guidelines.txt NISI: mailing list: nisi@merit.edu to join, mail to: nisi-request@merit.edu Uniform Resource Identifier WG: ============================== Chair: Larry Masinter (Xerox) The URI is the union of Uniform Resource Location and Uniform Resource Name. The idea is to identify information resources uniquely and to allow the location of these by navigational tools. U = Uniform R = Resource { N,L,C, .... } = { Name, Locator, Characteristic, ... } This WG started with a series of presentations. URA: (Yes a new one!) Leslie Daigle from BUNYIP talked about their work on "Uniform Resource Agents" and the URA architecture. This included the notion of a UR Agency which would manage URAs and queries about URAs, requests to invoke URAs, the communication of the results etc. URAs are objects and might identify thematically related resources. See http://www.bunyip.com for more details. Next the URN "Fest" was introduced. There are several different schemes for implementing URNs. Ron Daniel and Paul Hoffman have a draft document, which is based on Mitra's general syntax proposal. Michael Shapiro (NCSA) had a proposal based on a path scheme. Bill Arms had a scheme based on the use of a "handle" (based on some of their work on a global digital library). Keith Moore talked about his LIFN scheme. (Location Independent File Names). Mitra talked about the general syntax scheme (the original scheme developed by Mitra, Chris Weider and Michael Mealling following the IAB Information Infrastructure retreat in October 94). Michael has a URN testbed set up at Georgia Tech. There were many questions on technical issues and other non-technical issues (such as "Who will pay for the global name resolver?") and a great deal of discussion. It was decided that there would be a URN "bake-off" at the next-but-one IETF. Those with ideas should develop working code - and then they would be tested out using clients modified to understand each scheme. This WG had two sessions scheduled, with the URN discussion continuing on into the second session. John Kunze then presented the Z39.50 URL draft and the changes made to it; Roy Fielding presented his "relative URL" draft; and Michael Mealling presented the URC drafts. Note that Michael Mealling has a useful collection of pointers to related work at: http://www.gatech.edu/iiir/ Mailing list: uri@bunyip.com To join, mail to: uri-request@bunyip.com Archive: archives.cc.mcgill.ca Directory: /pub/uri Site Security Handbook ============================= Chair: Barbara Fraser - CERT This group is producing a new document for system and network administrators. They have a draft outline. It will include sections on: Site Security Policy Security Procedures: passwords backups access terminal rooms modems network Cryptography Configuration Firewalls Incident Handling Quality WG: =========== Chair: Mitra quality@sunsite.unc.edu To join, mail to: listserv@sunsite.unc.edu the text subscribe quality <full name> This group met briefly to decide to close down. No-one was willing or had time to work in this area, although it was felt to be an important area. It was noted that this WG might well be spun back up again if there were people prepared to contribute to the effort. This work is required, and it is expected that various information providers will start to work in this area. Once there is a nucleus of work in progress, a working group might have more chance of success, as it would be building on existing work rather than trying to initiate new work itself. Integration of Internet Information Resources Working Group (IIIR): ================================================================== Chair: Chris Weider - BUNYIP The purpose of this working group was to start to pull together some of the applications (WAIS, gopher, archie), to work on interoperability issues, what new tools should do and to discuss gateway protocol design and to write an information framework document. This group met to discuss whether or not to close down. This time the decision was yes, it should close. Before it closed... Stu Weibel (OCLC) reported on the Dublin (Ohio) "Metadata workshop". This consisted of 50 invited participants who met to discuss resource discovery problems and in particular the need for metadata. Chris Weider (chair of IIIR) has been elected with Erik Huizer (formerly Applications Area Director on the IESG) to the IAB (Internet Architecture/Activities Board). The IIIR list will be kept active. Mailing list: iiir@merit.edu To join, mail to: iiir-request@merit.edu Internet Schools Networking =========================== Chair: Jennifer Sellars - NASA Jodi Ito - Uni. Hawaii This group is designing a template for a description of school projects. The idea is that these will be put in an on-line directory which can be searched. RFC 1578/FYI22 needs updating to include a section on WWW etc. Pointers to exciting projects to use as examples are needed. Mailing list: isn-wg@unmvma.unm.edu To join, mail to: isn-wg-request@unmvma.unm.edu HTML ==== Chair: Dan Connolly - W3C There were two sessions for the HTML WG. Dan Connolly of the newly formed WorldWide Web Consortium (W3C) chaired the sessions. The first session concentrated on html version 2. Dave Raggett (HP, on secondment to W3C) presented the HTML 3.0 draft document. Features in html 3.0 include file upload, support for scripting (such as safe tcl, java), tables, maths, etc. Interesting was the attendance of members of the traditional mark up communities (for example those involved in marking up tables using the SGML CALS model for tables, those involved in "mathematical" publishing etc.). They had very useful input, and it was good to see them taking the IETF and the Web seriously. NCSA, Netscape and EIT were also represented. Mailing list: html-wg@oclc.org to join, mail to: listserv@oclc.org the text: subscribe html-wg <your first name> <your last name> Network Training Materials: ========================== Chair: Jill Foster - University of Newcastle Mark Prior (The Univ. Adelaide) is the co-chair of this Working Group. He was unable to attend this IETF. The following section is based on notes taken by Jodi Ito. The key items to be discussed were the catalogue of network training materials, review of available training materials, and using the network to deliver training. Discussion of the catalogue included review of the IAFA fields: addition of new fields, changing the names of existing fields, and categorization standards for various fields like country and languages. The group agreed on the addition of the following fields: audience, audience-level and [template] handle. Discussion regarding the "categories" field resulted in the division of training materials into 2 high-level categories: Documentation and Training Materials. The "Documentation" level was further subdivided into 3 areas: User Guides, Resource Guides, and Trainer/Instructor Guides. The "Training Materials" level was subdivided into: Presentation Materials (including speaker notes), Workshop exercises (including lab configuration information and the actual workshop exercises), and Self-paced Materials. The entries in the catalogue needs to be reviewed for quality and currency. Several people volunteered to review "chunks" of the catalogue. Summaries will be sent to the list. The group did note that many templates were not completely filled out and pointed out the need for an automated template verification process - upon submission, the template would be scanned automatically to ensure that key fields are completed. The Catalogue of Training Materials is available via the Web from the Univ. of Adelaide: http://coolabah.itd.adelaide.edu.au/TrainMat/catalogue.html The last item on the agenda was general discussion on using the network to deliver training. Several people mentioned using the Web to deliver training (which illustrated the need to to have "states" incorporated into the http protocol). Additionally, Jill is working on having PowerPoint registered as a MIME content type. Jill also mentioned that Joyce has been working on getting a time slot allocated on the MBONE to experiment with broadcasting training over the MBONE. Mailing list: network-training-tf@mailbase.ac.uk to join, mail to: mailbase@mailbase.ac.uk the text: join network-training-tf <your full name> Note this is a *working* list. Minutes etc are sent to the us-wg and wg-isus mailing lists. Concluding remarks ================== A good IETF on balance. The next IETF is scheduled for July 17-21 1995 in Stockholm, Sweden. This will only be the second time it has been held outside of North America. Finally, a reminder that these notes are my view of the IETF and that I have had less time than usual to "polish" them. They may not be an accurate view, and certainly do not cover the wide range of topics discussed at the workshop, nor even all the sessions I attended. This IETF was just before I was away on holiday - hence the delay. Hopefully the information is not too out of date and it has given you enough of a flavour of the meeting. If you are interested in subsequent developments or in more details on the above, please join the relevant mailing lists and look at their message archives.
