Network Working Group P. Barker INTERNET-DRAFT S.E. Kille University College London March 1991 The COSINE and Internet X.500 Schema Status of this Memo: This document suggests an X.500 Directory Schema, or Naming Architecture, for use in the COSINE and Internet X.500 pilots. The schema is independent of any specific 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 to this document includes a machine processable version of the schema This document also proposes a mechanism for allowing the schema to evolve in line with commonly held requirements. Proformas to support this process are included. It is important to note that this version of the document is a draft, and comments on the updating mechanisms are particularly welcome. Corrections and additions to the schema should now be sent the list, as described within. This draft document will be submitted to the RFC editor as a protocol specification. Distribution of this memo is unlimited. Please send comments to the authors or to the discussion group . Barker & Kille [page 1] The COSINE and Internet X.500 Schema DRAFT Version 1.1 1. Introduction Directory Services are a fundamental requirement of both human and computer communications' systems. Human users need to be able to look up various details about other people: for example, telephone numbers, facsimile numbers and paper mail addresses. Computing systems also need Directory Services for several purposes: for example, to support address look-ups for a variety of services, and to support user-friendly naming and distribution lists in electronic mail systems. Directory Services have recently been standardised and published as the 1988 CCITT X.500 / ISO IS9594 recommendations [1]. The standard provides a good basis for the provision of real services, and a considerable amount of Directory Service piloting activity is currently underway. In the U.S., the PSI White Pages Pilot [4] has stimulated use of X.500 on the Internet. In Britain, the U.K. Academic Community Directory Pilot [5] is similarly promoting use of X.500. 2. Motivation and aims of this document In a number of areas the X.500 standard only provides a basis for services. One such area is the Directory's Schema or Naming Architecture. The standard defines a number of useful object classes, in X.521, and attribute types, in X.520. These are intended to be generally useful across a range of directory applications. However, while these standard definitions are a useful starting point, they are insufficient as a basis for a large scale pilot directory. While it is possible for directory administrators to define their own sets of additional attribute types and object classes, this is undesirable for some common attributes and objects. The same objects and attribute types would be privately defined many times over. This would result in the directory's generality being diminished as remote systems would be unable to determine the semantics of these privately defined data types. A number of useful additions to the standard definitions were made in this note's forerunner, "The THORN and RARE Naming Architecture" [2]. These have been heavily used in early X.500 piloting activities. Furthermore, both the THORN and Quipu X.500 implementations have made use of these definitions. Barker & Kille [page 2] The COSINE and Internet X.500 Schema DRAFT Version 1.1 Since the afore-mentioned note was issued, a number of further requirements have come to light as the volume and variety of piloting activity has increased. Yet further requirements seem likely as the scale of X.500 pilot services increases. Thus, it is argued that it is not sufficient to merely reissue an updated version of the original note. The schema is a "living document" that needs procedures for: - Allowing submission of requests for new attributes and object classes to be added into the schema; - Checking for the redundancy of any previously defined attribute types and object classes. This document attempts to establish procedures to allow for the continual updating of the schema. Two proformas are set out for this purpose. In addition, descriptive detail is provided for the additional object classes and attribute types defined in the schema. These descriptions follow the style used in X.520 and X.521. Finally, also following the style adopted in the standards documents, appendices will include the entire schema. Plain text versions of the document's appendices are intended to be machine processable to allow derivation of a system's schema tables. Appendix C lists all the schema's object classes and attribute types in their respective ASN.1 macro formats. The scope and intended remit of this coordination activity should be clearly understood. - Esoteric and local, highly experimental requirements should continue to be met by private definitions. - Requirements which have support from more than one site will usually be integrated into the schema. Put in other words, the tendency will be for the inclusion, as opposed to the exclusion, of useful additions to the schema. - An attempt will be made to avoid duplication of object classes and attribute types for essentially similar real world objects. It is important to note that this version of the document is a draft, which is intended principally to provoke comments on the schema updating mechanisms proposed. Corrections to the schema Barker & Kille [page 3] The COSINE and Internet X.500 Schema DRAFT Version 1.1 should also be indicated to the authors. However, additions to the schema should not be submitted until a call is made for such enhancements. 3. What conformance to this schema means It is not reasonable to require that a DSA which supports this schema has specific code to handle each of the defined syntaxes. However, the following requirements are made of a system which claims conformance to this specification: 1. A DSA shall be able to store all of the attributes and object class values specified. (Note that this implies support for all the object classes and attribute types required by strong authentication as defined in X.509.) 2. A DUA shall be able to identify each attribute type and object class to the user, with an appropriate representation (e.g., a string). 3. These statement are qualified for large attributes values (>1kbyte). A conforming DSA does not have to store such attribute values, and a DUA does not have to display such values, although it must indicate their presence. The following are desirable, but not required: 1. For a DSA to match correctly on the basis of all attribute syntaxes defined 2. For a DSA to enforce the Object Class schema implied by these definitions 3. For a DUA to correctly display the attribute values (syntaxes) defined 4. For DUAs and DSAs to maintain compatibility with a previous version of the schema. 4. Requesting new object classes and attribute types This section defines a procedure for requesting new object Barker & Kille [page 4] The COSINE and Internet X.500 Schema DRAFT Version 1.1 classes and attribute types to be added to the schema. Proformas for object classes and attribute types are specified, and examples given of how to use them. As stated earlier, it is anticipated that the schema will evolve considerably over time. As X.500 is used to support a widening range of applications, there will be requirements for extensions to the schema. This document proposes formalising this procedure by requiring requests for additions to the schema to be submitted as completed proformas. This stipulation will greatly simplify subsequent revisions of the schema. There is one qualification to the above with respect to requests for modifications to an existing object class. If a modification to an object class merely involves additional, optional attributes, the object class will be enhanced as requested. Systems are expected to be resilient to such changes to the schema. However, requests to modify an object class, such that the mandatory attribute types require altering, will not be met. Instead, a new object class will be created, and the original object class expired following the scheme described in the next main section. It is anticipated that most requests for modifications to the schema will be met without any need for editorial intervention. Sometimes, however, some discussion between the submitter of a request and the schema's editor may be required. For example, the editor may have to judge the relative merits of two very similar requests and, as a result, one of the parties may not get quite what they want. In cases such as this where the submitter of a request feels aggrieved about an editorial decision, the requestor may appeal to a broader community by explaining their views to the mailing list osi-ds@cs.ucl.ac.uk. Heed will be paid to any consensus that emerges from discussions on the schema on this list. If it proves that this list is used almost solely for discussions on schema issues, a separate discussion list will be created. To facilitate the production of the afore-mentioned proformas, tools are included in Appendix B which will verify that a proforma has been correctly formatted. Completed proformas should be mailed to na-update@cs.ucl.ac.uk Barker & Kille [page 5] The COSINE and Internet X.500 Schema DRAFT Version 1.1 4.1. Object Class proforma This section gives an example, completed proforma for a new object class, alcoholic drink. A proforma for object class specified in BNF is included in Appendix A. Object Class: Alcoholic Drink Description: The Alcoholic Drink object class is used to define entries representing intoxicating beverages. ASN1OCMacro: alcoholicDrink OBJECT-CLASS SUBCLASS OF drink MUST CONTAIN { percentAlcohol} MAY CONTAIN { normalServing, hue} An object class description consists of three fields, separated by blank lines. The keywords Object Class, Description and ASN1OCMacro, and their suffixed colons, must be included exactly as above. The Object Class field should be used for a textual description of the object class. This will be at most three or four words. The Description field should contain some explanatory text about the intended use of the object class. This can run to a number of lines. The ASN1OCMacro field should follow the definition of the object class macro as specified in X.501. The above example shows the main features. There are many more examples which can studied in the section defining the Pilot Object Classes. 4.2. Attribute type proforma This section gives an example completed proforma for a new attribute type, hue (one of the attribute types in the alcoholic drink object class). Barker & Kille [page 6] The COSINE and Internet X.500 Schema DRAFT Version 1.1 Attribute Type: Hue Description: The Hue attribute type specifies the hue of an object. OCMust: OCMay: alcoholicDrink ASN1ATMacro:hue ATTRIBUTE WITH ATTRIBUTE SYNTAX caseIgnoreStringSyntax (SIZE (1 .. ub-hue)) ub-hue INTEGER ::= 256 An attribute type description consists of five fields, separated by blank lines. The keywords Attribute Type, Description, OCMust, OCMay and ASN1ATMacro, and their suffixed colons, must be included exactly as above. The Attribute Type field should be used for a textual description of the attribute type. This will be at most three or four words. The Description field should contain some explanatory text about the intended use of the attribute type. This can run to a number of lines. The OCMust field should contain a comma-separated list of object classes for which this attribute is mandatory. The OCMay field should contain a comma-separated list of object classes for which this attribute is optional. The ASN1ATMacro field should follow the definition of the attribute macro as specified in X.501. The above example shows some of the features. In particular, please note the format for specifying size constraints . Barker & Kille [page 7] The COSINE and Internet X.500 Schema DRAFT Version 1.1 5. Removing "old" object classes and attribute types. It is also important that object classes and attribute types which are no longer used or useful are removed from the schema. Some object classes and attribute types initially defined as pilot extensions may be included as standard definitions in future versions of the standard. In such a case, it is important that there should be a fairly rapid transition to the standard definitions. Another possibility is that newer, more specific definitions obviate the original definitions. Two things are essential. First, it is crucial that "old" definitions are retired as gracefully as possible. The intention to retire a definition will be sent to the osi-ds@cs.ucl.ac.uk mail list. In the absence of objections, the definition will be marked for expiry with a given expiry date. The definition will remain in the schema until the expiry date. Users of the schema should ensure that they make the transition to new, alternative definitions in the interim. Second, users of the schema must have the right to argue for the retention of definitions which they regard as necessary, there being no other definitions which closely meet their requirements. It is clearly impossible to lay down hard and fast rules on this point, as no two instances will ever be quite the same. It is intended that the refereeing on these matters will be sympathetic! As for requests for additions, an aggrieved user can "go to arbitration" by initiating a discussion on the osi- ds@cs.ucl.ac.uk mail list. 6. Object Identifiers Some additional object identifiers are defined for this schema. These are also reproduced in Appendix C. data OBJECT IDENTIFIER ::= {ccitt 9} pss OBJECT IDENTIFIER ::= {data 2342} ucl OBJECT IDENTIFIER ::= {pss 19200300} pilot OBJECT IDENTIFIER ::= {ucl 100} pilotAttributeType OBJECT IDENTIFIER ::= {pilot 1} pilotAttributeSyntax OBJECT IDENTIFIER ::= {pilot 3} pilotObjectClass OBJECT IDENTIFIER ::= {pilot 4} Barker & Kille [page 8] The COSINE and Internet X.500 Schema DRAFT Version 1.1 7.
