1.  Introduction

   The information bases meant to house registration and registrant data
   by way of modern directory standards as outlined within this series
   is dependent upon a comprehensive directory schema.

   The schema is used to define content and -- to a degree -- structure
   within the directory.



Coretta               Expires February 23, 2025                 [Page 4]

Internet-Draft        The OID Directory: Schema              August 2024


   In context, the definitions set forth are based on concepts derived
   from ITU-T Recommendations [X.660], [X.680], [RFC2578], et al.

   The intended end result is a directory service specially suited to
   operate as an object identifier registration authority service.

1.1.  Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY",
   and "OPTIONAL" in this document are to be interpreted as described
   in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in
   all capitals, as shown here.

1.2.  Acronyms Used

   See Section 1.3 of the RADIR I-D for all acronym references.

1.3.  Allocations

   This specification extends the previously defined I-D series OID root
   1.3.6.1.4.1.56521.101 per Section 1.6 of the RADIR I-D:

     - 1.3.6.1.4.1.56521.101.2 (schema)
     - 1.3.6.1.4.1.56521.101.2.3 (attributeTypes)
     - 1.3.6.1.4.1.56521.101.2.5 (objectClasses)
     - 1.3.6.1.4.1.56521.101.2.7 (nameForms)

   OIDs defined in this I-D correlate to the section numbers in which
   they originate.  For example, the 'n' attribute type defined within
   Section 2.3.1 is associated with the OID 1.3.6.1.4.1.56521.101.2.3.1.

   Should this I-D be elevated to RFC status, the aforementioned root
   OID prefix shall be made obsolete in favor of an IANA-assigned OID,
   at which point this I-D will be updated to reference the literal
   'IANA-ASSIGNED-OID' placeholder prefix, where appropriate.

1.4.  Well-Known Numeric OIDs

   This I-D references several well-known numeric OIDs defined by other
   parties or institutions, particularly as it pertains to the content
   within all of Section 2.3.  These numeric OIDs are shown below:

     - 1.3 (Identified-Organization, per clause A.4.2 of ITU-T Rec.
       [X.660])

     - 1.3.6 (dod, per Section 3.1 of [RFC1155])

     - 1.3.6.1 (Internet OID, per Section 3.1 of [RFC1155])

     - 1.3.6.1.1.16.1 (UUID syntax, matching rule and ordering rule, per
       Sections 2.1, 2.2 and 2.3 of [RFC4530] respectively)

       Section 3.3.13 of [RFC4517])

     - 1.3.6.1.4.1.1466.115.121.1.27 (Integer syntax, per Section 3.3.16
       of [RFC4517])

     - 1.3.6.1.4.1.1466.115.121.1.38 (OID syntax, per Section 3.3.26
       [RFC4517])

     - 1.3.6.1.4.1.1466.115.121.1.40 (Octet String syntax, per Section
       3.3.25 of [RFC4517])

2.  Schema Definitions

   This section discusses the particulars of the LDAP schema definitions
   made available through this I-D.

   These schema definitions described in this section are provided using
   LDAP description formats [RFC4512].  These elements are line-wrapped
   and indented for readability when needed.

   ALL definitions declared throughout the following subsections are to
   be considered "leaf nodes" (no subordinate registrations).

2.1.  LDAP Syntaxes

   No LDAP syntaxes are defined anywhere in this I-D series.  However,
   the topic of syntax is a recurring theme in ITU-T Recommendations
   [X.660], [X.680] and many other standards relevant to this series.

   This section serves only to advise the reader to consider the many
   defined (or cited) ABNF productions throughout Section 2.3.  While
   the base LDAP syntaxes used within this I-D are often insufficient
   in enforcing complete compliance with relevant syntax standards,
   most modern X.500/LDAP products support use of constraining rules
   of some form to narrow their scope.

   While the particulars of such product features are out of scope for
   this I-D series, the reader is nonetheless advised to make an effort
   to sufficiently constrain attribute value input so as to honor the
   relevant standard(s) in question.

2.2.  Matching Rules

   No LDAP matching rules are defined anywhere in this I-D series.

2.3.  Attribute Types

   The following subsections detail one hundred three (103) attribute
   types created for use within implementations of this specification.

Coretta               Expires February 23, 2025                 [Page 6]

Internet-Draft        The OID Directory: Schema              August 2024


   Please note that a great many of these attribute type definitions are
   sub types of attribute types defined in the following Standards, and
   as such are considered dependencies:

     - [RFC2079] for URI support
     - [RFC4519] for so-called "core" schema elements
     - [RFC4524] for Cosine schema elements

   If the nature of a particular directory implementation precludes the
   use of sub typed attributes, this specification may not be practical
   for adoption.

2.3.1.  'n'

   The 'n' attribute type allows the assignment of an unsigned integer
   used to represent the Number Form of a registration per ITU-T Rec.
   [X.680].

   A practical ABNF production, labeled 'number', is defined in Section
   1.4 of [RFC4512].

      ( 1.3.6.1.4.1.56521.101.2.3.1
          NAME 'n'
          DESC 'X.680, cl. 32.3: NumberForm'
          EQUALITY integerMatch
          ORDERING integerOrderingMatch
          SYNTAX 1.3.6.1.4.1.1466.115.121.1.27
          SINGLE-VALUE )

   Examples: "56521", "0"

2.3.2.  'dotNotation'

   The 'dotNotation' attribute type allows the assignment of one (1) OID
   to any non root registration.

   A practical ABNF production, labeled 'numericoid', is defined within
   Section 1.4 of [RFC4512].

      ( 1.3.6.1.4.1.56521.101.2.3.2
          NAME 'dotNotation'
          DESC 'X.680: OID in dotted notation'
          EQUALITY objectIdentifierMatch
          SYNTAX 1.3.6.1.4.1.1466.115.121.1.38
          SINGLE-VALUE )

    Examples: "1.3.6.1", "2.999"

2.3.3.  'iRI'

   The 'iRI' attribute type allows the assignment of one (1) or more
   OID-IRI values to a registration.

Coretta               Expires February 23, 2025                 [Page 7]

Internet-Draft        The OID Directory: Schema              August 2024


   A practical ABNF production for this attribute type, as derived from
   clause 34.3 of ITU-T Rec. [X.680], is as follows:

     subArcId   = SOLIDUS arcId *subArcId
     arcId      = intUV / nintUV
     nintUV     = 1*iunreserved ; non-integer unicode value
     intUV      = number        ; integer unicode value

     SOLIDUS    = "%x2f"        ; "/"

   The 'number' ABNF production originates in Section 1.4 of [RFC4512].
   The 'iunreserved' ABNR production originates within Section 2.2 of
   [RFC3987].

      ( 1.3.6.1.4.1.56521.101.2.3.3
          NAME 'iRI'
          DESC 'X.680, cl. 34: OID-IRI'
          EQUALITY octetStringMatch
          SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 )

   Examples: "/ITU-T", "/ISO/Identified-Organization", "/ASN.1"

2.3.4.  'aSN1Notation'

   The 'aSN1Notation' attribute type allows the assignment of an OID in
   ASN.1, or ITU-T Rec. [X.680] ObjectIdentifierValue, notation.

   A practical ABNF production for this attribute type is as follows:

     asn1notation = LCURL forms RCURL
     forms        = ( nanf / identifier ) *( SPACE ( nanf / number ) )

     SPACE        = "%x20"   ; " "
     LCURL        = "%x7b"   ; "{"

   It is NOT RECOMMENDED to assign this class to any entry which bears
   the 'rootArc' STRUCTURAL object class, per Section 2.5.1.  This class
   SHALL NOT appear on entries bearing the 'iTUTRegistration' (defined
   in Section 2.5.8) or 'iSORegistration' (per Section 2.5.9) class.

   This class extends use of the 'longArc' attribute type, as defined in
   Section 2.3.20.

   The 'x660Context' (Section 2.5.4), 'x667Context' (Section 2.5.5),
   'x680Context' (Section 2.5.6) and 'x690Context' (Section 2.5.7)
   object classes are super classes of this class.

2.5.11.  'spatialContext'

   The 'spatialContext' AUXILIARY class extends vertical and horizontal
   associative attribute types intended to describe the logical position
   of a registration in relation to adjacent registrations.

   Use of this class is entirely OPTIONAL, but can greatly aid in the
   creation of navigational interfaces which allow both horizontal and
   vertical movement across entire ancestries.

2.5.16.  'registrant'

   The 'registrant' object class allows for current, previous (first)
   and/or sponsorship data to be stored within an entry.

   This object class is STRUCTURAL, and cannot be combined with the
   'registration' object class within a single entry.

   Use of the 'registrant' object class within an RA DIT implies use
   of so-called dedicated authority entries, as described within the
   RADIT I-D.

2.6.  DIT Content Rules

   No DIT Content Rules are officially defined anywhere in this I-D
   series.

   If the X.500/LDAP product(s) in question registers positive support
   for these kinds of definitions, per Section 4.1.6 of [RFC4512], and
   the reader desires the ability to control the contents of any and all
   individual registration and/or registrant entries in a more granular
   manner, they are advised to consider the composition and use of one
   (1) or more custom rules of this design.

2.7.  Name Forms

   This section defines three (3) Name Forms for use in the composition
   of any DIT Structure Rules required, if supported by the X.500/LDAP
   product(s) in question.  See Section 4.1.7.2 of [RFC4512] for further
   details.

2.7.1.  'nRootArcForm'

   The 'nRootArcForm' name form is devised to control the RDN of the
   entries bearing the 'rootArc' STRUCTURAL object class.  Within the
   RECOMMENDED three dimensional model of this I-D series, use the 'n'
   (Number Form) attribute type is the preferred RDN component.

2.7.2.  'nArcForm'

   The 'nArcForm' name form is devised to control the RDN of the entries
   bearing the 'arc' STRUCTURAL object class.  Within the RECOMMENDED
   three dimensional model of this I-D series, the 'n' (Number Form)
   attribute type is the preferred RDN component.

          OC arc
          MUST n )

2.7.3.  'dotNotationArcForm'

   The 'dotNotationArcForm' name form is devised to control the RDN
   of the bearings bearing the 'arc' STRUCTURAL object class.  Within
   the STRONGLY DISCOURAGED two dimensional model of this I-D series,
   the 'dotNotation' (numeric OID) attribute type is the preferred RDN
   component.
