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.
The new AttributesType will use the OIDs 1.3.6.1.4.1.18060.1.1.0.3.N
The new ObjectClasses will use the OIDs 1.3.6.1.4.1.18060.1.1.0.4.N
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.
Syntaxes
We must define the minimum set of syntaxes.
Those are following the following grammar (from RFC 4512 ) :
<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
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 are the new one described in the following table :

---|---|---|---|
NameOrOid |
1.3.6.1.4.1.18060.1.1.0.1.1 |

MatchingRules
The Matching rules are deifned in RFC 4512 :
<MatchingRuleDescription> ::= <LPAREN> <WSP> <numericoid> <MRParameters> <SP> "SYNTAX" <SP> <numericoid> <extensions> <WSP> <RPAREN> <MRParameters> ::= ( <SP> "NAME" <SP> <qdstrings> | <SP> "DESC" <SP> <qdstring> | <SP> "OBSOLETE" )+
Here are the new MatchingRules :

ObjectClasses
The ObjectClass element is described in RFC 4512 :
<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 :
attributetype ( 2.5.4.0 NAME 'objectClass' DESC 'RFC2256: object classes of the entity' EQUALITY objectIdentifierMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 )

The other ones must be defined. Here is a table grouping all the missing elements :
