              SCIM Protocol: Multi-Value Paging Extension
                      draft-hunt-scim-mv-paging-00

Abstract

   The System for Cross-Domain Identity Management (SCIM) specifications
   define a profile of HTTP protocol and a schema that enable managing
   identities in cross-domain scenarios.  This specification extends
   SCIM protocol resource retrieval and query functions to enable paging
   of SCIM resources that contain large complex multi-valued attributes
   such as SCIM Groups.

1.  Introduction and Overview

   SCIM Protocol [RFC7644] is an application-level, HTTP protocol for
   provisioning and managing identity data on the web and in cross-
   domain environments such as enterprise to cloud, or inter-cloud
   scenarios.  The protocol supports creation, modification, retrieval,
   and discovery of core identity resources such as Users and Groups, as
   well as custom resources and resource extensions.

   The definition of resources, attributes, and overall schema are
   defined in the SCIM Core Schema document (see [RFC7643]).

   This specification extends SCIM resource retrieval and query
   functions to enable paging of SCIM resources that may contain
   attributes with large numbers of values.  For example, a SCIM Group
   may contain thousands or millions of members.

1.1.  Intended Audience

   This document is intended as a guide to extend SCIM protocol usage
   for both SCIM HTTP service providers and HTTP clients who may
   provision information to service providers or retrieve information
   from them.

1.2.  Notational Conventions

   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 [RFC2119].  These
