CURRENT_MEETING_REPORT_ Reported by Steve Hardcastle-Kille/UCL and Tim Howes/UMICH OSIDS Minutes Agenda Introduction and Welcome Chair Steve Hardcastle-Kille called the meeting to order after some furniture moving at 9:42am. Previous Minutes The Minutes from the February meeting at SRI and the May video conference were accepted without change. Liaison Reports o RARE WG3 (Erik Huizer - RARE) RARE WG3 has had one meeting since the last OSI-DS meeting. Erik reported the following: - PARADISE has now taken over operation of the COSINE X.500 pilot project. - The next RARE WG3 meeting will be in Zurich from 9/30 to 10/2. The meeting will include demos of lots of X.500 DUAs (for Macs, Unix, VMS, etc). Others are encouraged to attend and to contact Erik about bringing a DUA to demo. Erik also mentioned that there is the possibility of making funds available to someone from the US for the trip. o ISO/CCITT (Steve Hardcastle-Kille in lieu of a representative) There will be one more meeting before the 1992 white book comes out. This meeting will be in Berlin. o OIW (Russ Wright - LBL) Russ reported that at the OSI Implementors Workshop the following agreements had been reached: - Change the maximum APDU size to 256K (up from 32K), - Up the 6 line by 30 character postaladdress limit to 6 lines by 60 characters (see mtr's report below). 1 o NADF (Marshall Rose - unaffiliated) Marshall passed out a revised copy of the US Naming Scheme document now known as NADF 175 and reported the following: - NADF 175 will be submitted as an RFC soon. - NADF naming documents can be obtained from tymer@mcimail.com - NADF naming documents can be obtained from tymer@mcimail.com - NADF naming documents can be obtained from tymer@mcimail.com - The NADF expects to sponsor a pilot to test its agreements sometime in first quarter 1992. - The NADF was not pleased to hear about the OIW agreement about a postaladdress. Apparently, postaladdress limits are determined by a separate international agreement and cannot simply be changed to suit X.500. After some discussion, it was decided that OSI-DS should support the standard (i.e., 6 by 30) definition. o FOX (Steve Hotz - ISI) Steve reported the following FOX activities: - Approximately 85K NIC WHOIS entries are now online in SRI's DSA. - SRI is also working on a lightweight application to access this information in X.500. - SRI and Merit will work together to provide replication of the WHOIS information. - There are now RFC and FYI document subtrees under o=Internet. - Merit has put a Site Contacts database online under o=Internet, which the NSFNet network operations center is using. - Merit has also begun to put NIC profile information online. o PSI White Pages (Wengyik Yeong - PSI) Weng reported that the PSI WPP would be focusing on four areas in the near future: - Increasing reliability (through probing, e.g.) 2 - Transition to NADF naming scheme - Transition to the OSI-DS DSA naming scheme - Upgrading all pilot members to ISODE/QUIPU 7.0 o PARADISE (Steve Hardcastle-Kille - UCL) Steve reported that the PARADISE project was doing the following: - Running the world-wide root DSA at ULCC (Giant Tortoise) - Running a DUA service at ULCC for European organizations - Producing a glossy report - Helping other implementations, in particular Pizarro, join the pilot o AARN (Steve Hardcastle-Kille in lieu of a representative) Steve reported that there is a funded directory service pilot started in the Australian Academic Research Network and that they will be sending a representative to future OSI-DS meetings. Graham Rees at the University of Queensland is the AARN contact person. o NORDUNET (Geir Pedersen - NORDUNET) Geir reported that a directory services group is operating within NORDUNET. The group focuses on promotion of the directory within the Nordic countries. o CNI (George Brett - CNI) Coalition for Networked Information: - Members include Association for Research Libraries, CAUSE (administrative computing) and EDUCOM (academic computing). - 7 Working Groups: commercial publishing, non-commercial publishing, standards and architecture, management and professional education, K-20 education, directories and networked research centers (user services people). - George Brett and Peggy Seiden are involved in the directory Working Group. They are interested in a top node or directory of directories, and bibliography of bibliographies. They currently have a flat file, and are now working on an X.500 implementation with Merit. Also looking at a WAIS database. The Merit work involves a schema to represent the library of 3 congress enhanced MARC record. - Documentation on CNI's activities includes an article in Cause & Effect, v14no2, summer 1991. The Minutes of their last meeting can be made available to the list by George. There is also a listserv list called cnidir-l. - Art St. George of CNI is interested in K-12 use of networking. Internet Resource Descriptions in X.500 Document (OSI-DS 17) After much discussion, the general consensus on this document was that it needs to be rewritten with a more object-oriented approach. The feeling was that the object class for an Internet Resource should be broken up more in line with the standard's description of auxiliary and structural object classes. Document Progression Vint Cerf reported that all the technical RFCs were close to publication and would be out in ``a matter of weeks''. Because of the general importance to the Internet community of deploying a Directory Service, the overview and strategy documents should be merged and their scope widened. It was agreed that Steve H-K should revise the document, in association with appropriate IESG and IAB members. Review should be done via email, and that a separate subgroup not be formed. The scope of the Working Group was also considered, and the group was favourable to moving the activity out of the OSI area and into the Applications area. OID Assignment (OSI-DS 10, RFC 1239) It was decided that the existing OIDs will stay. A small debate followed about whether the current naming authority (under UCL) was ok, or whether it should be changed to the IANA. It was agreed that OIDs are just numbers, so the assignment authority is less important than stability. Currently assigned OIDs should not be adjusted. This had already been agreed between Steve H-K and Jon Postel. New OIDs would probably be assigned under an IANA subtree, subject to consensus with non-Internet users of this schema. It was agreed that this document could and should progress rapidly to RFC. Requirements Specification Document (OSI-DS 18) This document had been drafted after an agreement at the videoconference. After some discussion, it was agreed that a document of this nature would be important in the future, but was premature. It should be put on ice for now. More Resources Description Document Discussion 4 Mark Knopper of Merit said he was interested in putting NSAPs in the DIT and doing reverse lookups. Along with Chris Weider, he volunteered to write something up by mid-September on how to do this. NIC Profile Information Document (OSI-DS 16) After some discussion, it was agreed that Chris Weider should rewrite this document along the same object-oriented lines as discussed previously. There was also some discussion about how this information should be organized in the DIT, since some NICs are real organizations, others aren't, some are listed in other parts of the tree, others aren't. Steve H-K drew a diagram describing a structure that could accommodate both situations, and it was generally approved. K-12 Schema Document It was agreed that this document suffered from the same object-oriented concerns as the others and should be rewritten. Also, it was decided that a companion document addressing DIT structure for these objects should be produced. Chris Weider and Mark Knopper were elected for both tasks. Network Infrastructure Information in X.500 This document is already being rewritten and was not discussed. Pictures in the Directory Russ Wright presented a brief overview of the problem (summary: the g3fax format is bad), and a potential new format that is better (JPEG). It was agreed that JPEG is a step forward, but more study is needed on the transition path, potential size limits, etc. Russ Wright, Peter Yee, Tim Howes, and Mark Smith (in absentia) volunteered to look into these issues. Quality of Service (OSI-DS 15) The QOS definitions were generally accepted, and the next step is to start making use of these attributes now that the syntax handlers are available in QUIPU 7.0. Russ Wright, Erik Huizer, and Tim Howes volunteered to try incorporating QOS into some DUAs to gain some experience with its use. All of the represented pilots agreed to install the appropriate attributes into their DITs. Both efforts were needed to make an effective test of the Internet Draft. The Internet Draft should not be submitted as an RFC until results of this piloting, and probable modifications to the Internet Draft, had been done. NADF Naming Document NADF 175 is now considered Stable and a Good Thing by NADF, and will be released as an RFC Real Soon Now. Naming Guidelines Document (OSI-DS 12) 5 After some discussion about multi-national organization naming, it was agreed that this document should be progressed to RFC status pending ironing out of some minor issues which will be done via email. AOB Erik Huizer made a request for someone from the US to look into issues involving security/privacy laws in the US that might relate to X.500. This is something that has come up several times in Europe. Next Meeting Steve would like to have the next OSI-DS meeting around Interop.
