Abstract

CORBA [CORBA] is the Common Object Request Broker Architecture defined by the Object Management Group. This document defines the schema for representing CORBA object references in an LDAP directory [LDAPv3].

1. Introduction

This document assumes that the reader has a general understanding of CORBA.

Traditionally, LDAP directories have been used to store data. Users and programmers think of the directory as a hierarchy of directory entries, each containing a set of attributes. You look up an entry from the directory and extract the attribute(s) of interest. For example, you can look up a person’s telephone number from the directory. Alternatively, you can search the directory for entries with a particular set of attributes. For example, you can search for all persons in the directory with the surname "Smith".

CORBA applications require access to CORBA objects. Traditionally, CORBA applications have used the COS Naming service for storage and retrieval of CORBA object references. When deployed in environments with a directory, CORBA applications should be able to use the directory as a repository for CORBA object references. The directory provides a centrally administered, and possibly replicated, service for use by CORBA applications distributed across the network.

RFC 2714 Schema for CORBA Object References October 1999

For example, an application server may use the directory for "registering" CORBA objects representing the services that it manages, so that a client can later search the directory to locate those services as it needs.

The motivation for this document is to define a common way for applications to store and retrieve CORBA object references from the directory. Using this common schema, any CORBA application that needs to read or store CORBA object references in the directory can do so in an interoperable way.

Note that this schema is defined for storing CORBA "object references," not CORBA objects in general. There might be other ways to store CORBA objects in an LDAP directory but they are not covered by this schema.

2. Representation of CORBA Object References

This document defines schema elements to represent a CORBA object reference in LDAP directory. Applications in possession of a reference to an object can invoke calls on that object. Such a reference is termed an "interoperable object reference," or IOR. Access to CORBA objects by using IORs is achieved transparently to the application, by means of the General Inter-ORB Protoco...
