Abstract
This document defines a multipurpose internet mail extensions (MIME)
directory profile for holding a lightweight directory access protocol
(LDAP) schema. It is intended for communication with the Internet
schema listing service.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [4].
1. Overview
This document defines how a MIME type may be used to transfer a
single LDAPv3 schema definition.
A schema for use with LDAPv3 consists of any number of object class,
attribute type, matching rule and syntax definitions. These concepts
are defined in the LDAPv3 protocol definition [2]. The schema MAY
have a numeric OID assigned to it by a schema listing or registration
service.
A schema may import definitions from another schema. Schema imports
are not, however, transitive.
For example, a schema contains a definition for a "modem" object
class, which is to be defined as a subclass of the X.521 "device"
object class. In this case, the schema MUST import the definitions
of X.521.
