The X.500 directory provides a powerful mechanism for storing and
retrieving information about objects of interest.  To interpret the
information stored in the directory, the schema must be known to all
the components of the directory.  Presently, there are no means other
than ftp to distribute schema information across the Internet.  This
is proving to be a severe constraint as the Directory is growing.
This document presents a solution to the schema distribution problem
using the existing mechanisms of the directory.  A naming scheme for
naming schema objects and a meta-schema for storing schema objects is
presented.  The procedures for fetching unknown schema from the
directory at runtime are described.  This RFC is a product of the
Access, Searching and Indexing of Directories Working Group of the
IETF.
