     2.  Abstract
     
     This  document  defines  a schema for the Routing Policy Specification
     Language (RPSL).  It is expected that this schema will  be  useful  in
     providing  a  standardized  format  for  representation of RPSL within
     LDAP-based directory services.
     
     
     3.  Introduction
     
     The  Routing  Policy  Specification  Language  (RPSL),  described   in
     [6]-[8],  provides a means for the high-level specification of routing
     policies.  To date,  efforts  at  representing  routing  policies,  as
     descrbed  in [9]-[10], have relied on proprietary schemas.  This docu-
     ment describes how routing policies may be represented  in  LDAP-based
     directory services.
