Introduction

We want to store the schema into ADS as any other entries. We have to define the minimum set of ObjectClasses an AttributeTypes needed to be able to bootstrap the schema.

...

Note

The new Syntaxes will use the OIDs OIDs 1.3.6.1.4.1.18060.10.14.0.10.N
The new MatchingRules will use the OIDs 1.3.6.1.4.1.18060.10.14.0.21.N
The new AttributesType will use the OIDs 1.3.6.1.4.1.18060.10.14.0.32.N
The new ObjectClasses will use the OIDs 1.3.6.1.4.1.18060.10.14.0.43.N
The new DITStructureRules will use the OIDs 1.3.6.1.4.1.18060.0.4.0.4.N
The new NameForms will use the OIDs 1.3.6.1.4.1.18060.0.4.0.5.N

We will use We will use OIDs 1.3.6.1.4.1.18060.1.1.0.0.N for Meta objects.

Here, the prefix 1.3.6.1.4.1.18060 is the one declared to IANA to represent the Apache Foundation and the next 1.1 values are used specifically for Apache Directory.

Elements of the Meta-Schema

The MetaSchema will be presented in MetaSchema schema, but before, we must define some elements in this page.

SyntaxesSyntaxes

We must define the minimum set of syntaxes.

Those are following the following grammar (from RFC 4512 ) :

Code Blocknoformat
<SyntaxDescription> ::= <LPAREN> <WSP> <numericoid> ( <SP> "DESC" <SP> <qdstring> )? <extensions> <WSP> <RPAREN>

Only one is already defined: in http://www.rfc-archive.org/getrfc.php?rfc=4517

34 of them are defined in RFC 4517. For instance, here the definition of Boolean syntax :

No Format


3.3.3.

Code Block


3.3.3.  Boolean

   A value of the Boolean syntax is one of the Boolean values, true or
   false.  The LDAP-specific encoding of a value of this syntax is
   defined by the following ABNF:

      Boolean = "TRUE" / "FALSE"

   The LDAP definition for the Boolean syntax is:

      ( 1.3.6.1.4.1.1466.115.121.1.7 DESC 'Boolean' )

   This syntax corresponds to the BOOLEAN ASN.1 type from [ASN.1].

They Here are the new one we need to implement the MetaSchema, described in the following table :

Desc

OID

Extensions

1.3.6.1.4.1.18060.10.14.0.10.1

-

Should be one of those 4 strings :

userApplications

distributedOperation
dSAOperation

MatchingRules

The Matching rules are deifned in RFC 4512 :

number	1.3.6.1.4.1.18060.0.4.0.0.4	-	Must be a number
oidLen	1.3.6.1.4.1.18060.0.4.0.0.5	-	Must be a valid numeric oid followed by a length constraint
objectName	1.3.6.1.4.1.18060.0.4.0.0.6	-	Must be a valid name a-zA-Z(a-zA-Z0-9-;)*

MatchingRules

The Matching rules are defined in RFC 4512 :

No Format


<MatchingRuleDescription> ::= <LPAREN> <WSP>
         <numericoid> <MRParameters>

Code Block


<MatchingRuleDescription> ::= <LPAREN> <WSP>
         <numericoid> <MRParameters>
         <SP> "SYNTAX" <SP> <numericoid>
         <extensions> <WSP> <RPAREN>

<MRParameters> ::=
    ( <SP> "NAME" <SP> <qdstrings> |
    <SP> "DESC" <SP> <qdstring> |
    <SP> "OBSOLETESYNTAX" <SP> )+

Here are the new MatchingRules :

<numericoid>
         <extensions> <WSP> <RPAREN>

<MRParameters> ::=
    ( <SP> "NAME" <SP> <qdstrings> |
    <SP> "DESC" <SP> <qdstring> |
    <SP> "OBSOLETE" )+

Here are the new MatchingRules :

Name	Name	OID	Desc	Obsolete	Syntax
OidMatch	1.3.6.1.4.1.18060.1.1.0.2.1	Match an OID	no	*OID*	-
BooleanMatch	1.3.6.1.4.1.18060.1.1.0.2.1 2	Match a Boolean	no	Boolean	-

UsageMatch	1.3.6.1.4.1.18060.1.1.0.2.4 5	Match an attributeType Usage	no	*Usage*	-

...

The ObjectClass element is described in RFC 4512 :

Code Blocknoformat

<ObjectClassDescription> ::=
          <LPAREN> <SP> <numericoid> <ocparameters> <extensions> <WSP> <RPAREN>

// Each parameters should not be seen more than once
<ocparameters>  ::=
    ( <SP> "NAME" <SP> <qdescrs>
    | <SP> "DESC" <SP> <qdstring>
    | <SP> "OBSOLETE"
    | <SP> "SUP" <SP> <oids>
    | <SP> ( "ABSTRACT" | "STRUCTURAL" | "AUXILIARY" )
    | <SP> "MUST" <SP> <oids>
    | <SP> "MAY" <SP> <oids> )+

Here we have some elements which are already in the schema :
