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 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 | rules | ||
---|---|---|---|---|---|
NameOrOid objectClassType | 1.3.6.1.4.1.18060.10.14.0.10.1 | - | Should be one of those 3 strings :
| ||
numericOid | Must be a valid Name or a valid OID | Type | 1.3.6.1.4.1.18060.10.14.0.10.2 | - | Must be a valid numeric OID |
attributeTypeUsage | Should be one of those 3 strings :
| Usage | 1.3.6.1.4.1.18060.10.14.0.10.4 3 | - | Should be one of those 4 strings :
|
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 |
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>
<SP> "SYNTAX" <SP> <numericoid>
<extensions> <WSP> <RPAREN>
<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> "OBSOLETEDESC" )+ <SP> <qdstring> | <SP> "OBSOLETE" )+ |
Here are the new MatchingRules :
Name | OID | Desc | Obsolete | Syntax | Extensions |
---|---|---|---|---|---|
OidMatch | 1.3.6.1.4.1.18060.1.1.0.2.1 | Match an OID | no | OID | - |

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 :
