Subject: Agenda for San Diego IETF
Gang: The DISI meeting is on Thursday, March 19, 1992 in San Deigo, from 9:30 - 12:00 noon. The agenda is as follows: 1: Discussion of old minutes 2: Progression of DISI Internet Drafts to RFCs 3: Discussion and assignment of new papers. Papers to be discussed during the meeting include a benchmarking paper, a "how to join a pilot" or a "Pilot Catalog" paper, a "how to set up a DSA" paper, an "advanced usages" document, and a "X.500 bibliography" paper which contains pointers to relevant documents. Now, Ruth Lang sent along a European document called "A guide for DSA managers" sometime in December. This has a few pointers for a document for us, so I am including it here again. Please come prepared to discuss this. See you in San Diego! Chris ---------------------------------------------------------------- HOW TO GET STARTED A Guide for DSA Managers Introduction The PARADISE project is funded by the COSINE project to provide a pilot international directory service across Europe with connectivity to North America and the rest of the world. It enables members of the academic, commercial and governmental research community to look up information about colleagues and find, for example, their electronic mail addresses. In keeping with the goals of OSI, the commitment of this pilot is to be non- implementation specific and the PARADISE project is looking to involve as many stable products based on the X.500/ISO 9594 standard as possible in the directory. Choosing an Implementation The most common implementation currently used in the pilot is QUIPU (release 6.8) which is packaged with the public domain ISODE software. PARADISE will be making the first release of a packaged DSA and DUA based upon QUIPU available in summer 1991 from X-Tel Services. A list of other implementations used in the pilot with details of reference sites and support is available from PARADISE (imps.txt from the info-server - see below) together with a listing of other implementations commercially available. To ensure that the implementation you choose will interoperate within the pilot, please consult the document "A COSINE/Internet Schema" (na.txt from the info-server) and let the helpdesk know how closely you will conform to it. Setting up a PARADISE X.500 directory If you are living in a country where there is no existing national pilot or there is no-one responsible for your country's node in the directory tree, you may wish to run your country's entry. If you are not sure whether your country is represented in the global tree, contact the PARADISE helpdesk (see below). (A) Starting a national directory subtree The principal requirements for joining the directory are that: o a DSA should be available preferably using both X.25 over PSPDN (PSS, Janet IXI) and the Internet (using RFC-1006 over TCP/IP); and o be able to contact the Giant Tortoise DSA at ULCC which holds the PARADISE root node and provides the glue at the top of the directory tree. Except in circumstances where it has been agreed with the PARADISE project that your DSA route via Giant Tortoise for access to other national DSAs, you will need to maintain the presentation addresses of the other national DSAs in your DSA configuration. These are centrally available (addresses.txt from the info-server) or by asking the helpdesk. For further information on representing such addresses, refer to the document on string encoding (string.txt from the info-server). Contact needs to be made with the helpdesk to let them know that you are trying to connect. If you wish to master your country's name space, then it needs to be pointed to for the benefit of the rest of the directory. If you are using an implementation other than QUIPU, you will need to perform interconnection tests with a PARADISE test DSA to demonstrate that you can read data and that your data can be read. As pilot activities grow in your country you will be expected to demonstrate interoperability with any other implementation that wishes to join the pilot. The PTT Telecom's Laboratory in Groningen, Netherlands are responsible in the project for looking at interoperability problems and if you are having difficulties, you should contact them (see below). (B) Starting a DSA below the country level To become fully registered in the PARADISE pilot you will need to register your organisation with the PARADISE representative in your country who will be responsible for managing the DSA mastering your country level entry in the global tree. If you're not sure who this is, contact the helpdesk. You will need to be running an X.500 Directory System Agent (DSA) which holds data representing your organisation and be available either using X.25 over PSPDN (PSS or IXI) or the Internet (using RFC-1006 over TCP/IP). It is in the spirit of the pilot to make some or all of your organisational telephone and/or email data publicly available for other pilot sites to look at via the X.500 protocol (that is, allow them to read data explicitly made available to them). Similarly other pilot sites will make their data available to you. You will have to consult with your official national name registration authority to choose (or be allocated) a relative distinguished name (RDN) and register it. If there is no such authority in your country and your national pilot is not in a position to help, consult the "Naming Guidelines" document available from the info-server. Your organisation can be registered at the country level of the tree, or if your organisation is not a national one, and you do not wish to be registered under the country node of the tree, you can opt to be registered under a locality; for example "c=FR, locality=Paris". There is as yet no standard policy across the PARADISE pilot as to the use of locality naming components and it would be advisable to discuss this further with your national representative and/or the PARADISE Project. Any cost involved in joining the pilot will vary from country to country and will be dependent on the nature of your organisation and what affiliation (if any) you have to your national pilot body. In many countries there is as yet no pricing mechanism in place. There is an informal agreement in most national pilots that data found in the directory is for personal use only, for example to get the telephone number of somebody you want to call. By registering your organisation in the pilot, you are seen to have agreed to this principle. Any use of the data for generating mailing lists or the like, without permission of the recipients is frowned upon and strongly discouraged. An attribute has been defined in the COSINE/Internet Schema which in future will allow users to indicate whether they wish their names to be added to lists. All data in your DSA should be registered under your national Data Protection Act or equivalent for worldwide access and it will be assumed that all organisations registering in the pilot have suitable data protection registrations. To register your organisation you will need to supply your national pilot with the Distinguished Name both that you wish your organisation to be registered with, and that of your DSA. For providing your DSA addresses, refer to the NSAP document (nsap.txt from the info-server). Having registered your organisation you have a commitment to making your DSA(s) available to other pilot sites. DSAs which are consistently unavailable may in some countries be deregistered from the pilot. In order to maintain a high profile of service DSA availability, sites should follow the guidelines outilined in the draft "Quality of Service" (qos.txt from the info-server). This allows users of the Directory to detect which DSAs are experimental, and also gives an indication as to the completeness and currency of the data in the Directory. An important part of the Pilot service is replication. Replication is not covered by the X.500(88) protocol. However, the pilot service achieves replication using the protocol defined in a draft document on replication (repl- req.txt from the info-server). Your national pilot should be able to offer replication services. This means holding copies of entries immediately below the root and the entries below all the country entries, then making them available to you via the draft replication protocol mentioned above. Currently there are two major networks involved in the global pilot - PSPDN and Internet. If your DSA is only connected to one of these networks you may require a DSA Relay service, details of which you can obtain from your national pilot or the helpdesk. The relay DSA service is a DSA that has access to both networks and is prepared to chain queries to DSA on one network on behalf of your DSA which is on the other. (C) Running a remote DSA through your National Pilot If you do not have a DSA yet, but wish to register your organisation, you may be able to supply your national pilot with your organisational information which can then be registered in the directory with possibly some service charge. If you do not have the facilities to run a DSA, another organisation within your national pilot may be able to run a DSA on your behalf. If this is not possible, contact the helpdesk and alternative arrangements might be found. (D) Running a remote DSA through PARADISE For those COSINE countries which do not have a national pilot, PARADISE provides a DSA to take the country level entry and up to a limited number of organisations per country. This number is currently ten but will be reviewed regularly. This service is primarily intended for SMEs (small-to-medium size enterprises) but other requests will be considered on a case by case basis. There will be an appropriate administrative charge for this service. Input and maintenance of organisational data will be the responsibility of individual organisations. Interactive access will be provided to carry out this task.

Summary of Relevant Documentation Index index.txt [**] An index of all documents centrally available from PARADISE including those referred to here. Implementations in imps.txt [**] PARADISE This document contains a brief description of each implementation connected to the international pilot with a list of reference sites and help points as well as other known stable X.500 products a commercially available. This document is intended to reflect an up-to-date picture on X.500 implementations and comments are welcomed. Presentation addresses.txt [**] Addresses A up-to-date listing of all country-level DSA presentation addresses. PARADISE international.txt International A six-monthly report produced by the project Report giving a snapshot of X.500 activity in each COSINE country as well as North America and the rest of the world with details of contact points, implementations used and the extent of each country's directory sub-tree. This is a living document and will be updated with the latest information about national pilot status as and when it is received. COSINE/Internet na.txt X.500 Schema An X.500 Directory Schema (or Naming Architecture) for use in PARADISE and the Internet pilots. The schema is independent of any particular implementation. As well as indicating support for the standard object classes and attributes, a large number of generally useful object classes and attributes are also defined. An appendix includes a machine processable version of the schema. The document also proposes a mechanism for allowing the schema to evolve in line with commonly held requirements. proformas to support this process are included. This is a living document and comments on the updating mechanism are welcomed. Naming Guidelines structure.ps for Directory structure.txt Pilots Deployment of a directory will benefit from following certain guidelines. This document defines a number of guidelines which are recommended. Conformance to these guidelines will be recommended for national pilots. Replication repl-req.ps Requirements repl-req.txt This draft document on the replication requirements to provide an Internet Directory using X.500 concerns itself with certain deficiencies of the 1988 standard which can only be addressed by use of additional protocol or procedures for distributed operation. A String Encoding string.ps of Presentation string.txt Addresses There a number of environments where a simple string encoding of Presentation Addresses is desirable. This specification defines such a representation. An Interim Approach nsap.ps to use of Network nsap.txt Addresses The OSI Directory specifies an encoding of Presentation Address, which utilises OSI Network Addresses as defined in the OSI Network layer standards. The OSI Directory, and any OSI application utilising the OSI Directory must be able to deal with these Network Addresses. Currently, most environments cannot cope with them. It is not reasonable or desirable fro groups wishing to investigate and use OSI Applications in conjunction with the OSI Directory to have to wait for the lower layers to sort out. Handling QOS in qos.ps the Directory qos.txt This document describes a mechanism for specifying the Quality of Service for DSA Operations and Data in the Internet Pilot Directory Service. Managing the X.500 manage.txt [**] Directory Pilot For over two years there has been a pilot distributed directory service. The management of this has passed to the COSINE PARADISE project. PARADISE manages the top-level country data for the participating COSINE countries in Europe and co-ordinates with pilots in North America and the rest of the world.
