    <abstract>
      <t>The System for Cross-Domain Identity Management (SCIM) specification
      is designed to make managing user identity in cloud based applications
      and services easier. The specification suite builds upon experience with
      existing schemas and deployments, placing specific emphasis on
      simplicity of development and integration, while applying existing
      authentication, authorization, and privacy models. Its intent is to
      reduce the cost and complexity of user management operations by
      providing a common user schema and extension model, as well as binding
      documents to provide patterns for exchanging this schema using standard
      protocols. In essence, make it fast, cheap, and easy to move identity in
      to, out of, and around the cloud.</t>

      <t>This document provides a platform neutral schema and extension model
      for representing users and groups in JSON format. This schema is
      intended for exchange and use with cloud service providers. An HTTP
      protocol binding document is also provided.</t>

    <section anchor="overview" title="Introduction and Overview">
      <t>While there are existing standards for describing and exchanging user
      information, many of these standards can be difficult to implement
      and/or use; e.g., their wire protocols do not easily traverse firewalls
      and/or are not easily layered onto existing web protocols. As a result,
      many cloud providers implement non-standardized protocols for managing
      users within their services. This increases both the cost and complexity
      associated with organizations adopting products and services from
      multiple cloud providers as they must perform redundant integration
      development. Similarly, cloud services providers seeking to
      inter-operate with multiple application marketplaces or cloud identity
      providers must be redundantly integrated.</t>

      <t>SCIM seeks to simplify this problem through a simple to implement
      specification suite that provides a common user schema and extension
      model, as well as binding documents to provide patterns for exchanging
      this schema via an HTTP based protocol. It draws inspiration and best
      practice, building upon existing user protocols and schemas from a wide
      variety of sources including, but not limited to, existing services
      exposed by cloud providers, PortableContacts, vCards, and LDAP directory
      services.</t>

      <t>This document provides a JSON based schema and extension model for
      representing users and groups, as well as service provider
      configuration. This schema is intended for exchange and use with cloud
      service providers and other cross-domain scenarios. An HTTP protocol
      binding document is provided separately.</t>

      <t>A resource is a collection of attributes identified by one or more
      schemas. Minimally, an attribute consists of the attribute name and at
      least one simple or complex value either of which may be multi-valued.
      SCIM schema defines the data type, plurality and other distinguishing
      features of an attribute. Unless otherwise specified all attributes are

      additional values indicating extended schemas that are in use. Schema
      extensions SHOULD NOT redefine any attributes defined in this
      specification and SHOULD follow conventions defined in this

      URI SHALL be used as a JSON container to distinguish attributes

            used by the user to directly authenticate to the service provider.
            Often displayed to the user as their unique identifier within the
            system (as opposed to id or externalId, which are generally opaque
            and not user-friendly identifiers). Each User MUST include a

            <t hangText="displayName">The name of the user, suitable for
            display to end-users. Each user returned MAY include a non-empty
            displayName value. The name SHOULD be the full name of the User
            being described if known (e.g. <spanx style="verb">Babs Jensen</spanx>
            or <spanx style="verb">Ms. Barbara J Jensen, III</spanx> ), but

            instead of <spanx style="verb">Robert</spanx>. This attribute
            SHOULD NOT be used to represent a User's username (e.g. bjensen or

            used.</t>

            <t anchor="preferredLanguage"
            hangText="preferredLanguage">Indicates the user's preferred
            written or spoken languages and is generally used for selecting a
            localized User interface. The value indicates the set of natural
            languages that are preferred. The format of the value is same as
            the Accept-Language header field (not including
            "Accept-Language:") of HTTP and is specified in <xref
            target="RFC7231">Section 5.3.5 of</xref>. The intent of this value
            is to enable cloud applications to perform matching of language
            tags <xref target="RFC4647"/> to the user's language preferences
            regardless of what may be indicated by a user agent (which might
            be shared), or in a non-user present interaction (such as in a
            delegated OAuth2 <xref target="RFC6749"/> style interaction) where
            normal HTTP Accept-Language header negotiation cannot take
            place.</t>

            <t hangText="locale">Used to indicate the User's default location
            for purposes of localizing items such as currency, date time
            format, numerical representations, etc. A valid value is a
            language tag as defined in <xref target="RFC5646"/>. Computer
            languages are explicitly excluded.</t>

            <t>A language tag is a sequence of one or more case-insensitive
            sub-tags, each separated by a hyphen character ("-", %x2D). For
            backwards compatibility reasons, servers MAY accept tags separated
            by an underscore character ("_", %5F). In most cases, a language
            tag consists of a primary language sub-tag that identifies a broad
            family of related languages (e.g., "en" = English) which is
            optionally followed by a series of sub-tags that refine or narrow
            that language's range (e.g., "en-CA" = the variety of English as
            communicated in Canada). Whitespace is not allowed within a
            language tag. Example tags include: <figure align="center">
                <artwork align="center">fr, en-US, es-419, az-Arab, x-pig-latin, man-Nkoo-GN</artwork>
              </figure> See <xref target="RFC5646"/> for further
            information.</t>

            <t hangText="timezone">The User's time zone in IANA Time Zone
            database format <xref target="RFC6557"/>, also known as "Olson"
            timezone database format <xref target="Olson-TZ"/> ; For example:
            <spanx style="verb">America/Los_Angeles</spanx>.</t>

            <t hangText="active">A Boolean value indicating the user's
            administrative status. The definitive meaning of this attribute is
            determined by the service provider. As a typical example, a value
            of true infers the user is able to login while a value of false
            implies the user's account has been suspended.</t>

            <t hangText="password">The user's clear text password. This
            attribute is intended to be used as a means to specify an initial
            password when creating a new User or to reset an existing User's
            password. Password policies and the ability to update or set
            passwords are out of scope of this document. The mutability of
            this attribute is <spanx style="verb">writeOnly</spanx> indicating
            the value MUST NOT be returned by a service provider in any
            form.</t>

      <section title="Multi-valued Attributes">
        <t>The following multi-valued attributes are defined.</t>

        <t><list style="hanging">
            <t hangText="emails">E-mail addresses for the User. The value
            SHOULD be canonicalized by the service provider, e.g. <spanx
            style="verb">bjensen@example.com</spanx> instead of <spanx
            style="verb">bjensen@EXAMPLE.COM</spanx>. Canonical type values of
            <spanx style="verb">work</spanx>, <spanx style="verb">home</spanx>,
            and <spanx style="verb">other</spanx>.</t>

            <t hangText="phoneNumbers">Phone numbers for the user. The value
            SHOULD be canonicalized by the service provider according to
            format in <xref target="RFC3966"/> e.g. 'tel:+1-201-555-0123'.
            Canonical type values of <spanx style="verb">work</spanx>, <spanx

            <spanx style="verb">fax</spanx>, <spanx style="verb">pager</spanx>,
            and <spanx style="verb">other</spanx>.</t>

            <t hangText="ims">Instant messaging address for the user. No
            official canonicalization rules exist for all instant messaging
            addresses, but service providers SHOULD, when appropriate, remove
            all whitespace and convert the address to lowercase. Instead of
            the standard canonical values for type, this attribute defines the
            following canonical values to represent currently popular IM
            services: <spanx style="verb">aim</spanx>, <spanx style="verb">gtalk</spanx>,
            <spanx style="verb">icq</spanx>, <spanx style="verb">xmpp</spanx>,

            and <spanx style="verb">other</spanx>.</t>

            <t hangText="photos">URL of a photo of the User. The value SHOULD
            be a canonicalized URL, and MUST point to an image file (e.g. a
            GIF, JPEG, or PNG image file) rather than to a web page containing
            an image. Service providers MAY return the same image at different
            sizes, though it is recognized that no standard for describing
            images of various sizes currently exists. Note that this attribute
            SHOULD NOT be used to send down arbitrary photos taken by this
            user, but specifically profile photos of the user suitable for
            display when describing the user. Instead of the standard
            canonical values for type, this attribute defines the following
            canonical values to represent popular photo sizes: <spanx
            style="verb">photo</spanx>, <spanx style="verb">thumbnail</spanx>.</t>

            <t hangText="addresses">A physical mailing address for this user.
            Canonical type values of <spanx style="verb">work</spanx>, <spanx
            style="verb">home</spanx>, and <spanx style="verb">other</spanx>.
            The value attribute is a complex type with the following
            sub-attributes. All sub-attributes are OPTIONAL. <list

                <t hangText="formatted">The full mailing address, formatted
                for display or use with a mailing label. This attribute MAY
                contain newlines.</t>

                <t hangText="streetAddress">The full street address component,
                which may include house number, street name, P.O. box, and
                multi-line extended street address information. This attribute
                MAY contain newlines.</t>

                <t hangText="country">The country name component. When
                specified the value MUST be in ISO 3166-1 alpha 2 "short" code

              </list></t>

            <t hangText="groups">A list of groups that the user belongs to,
            either thorough direct membership, nested groups, or dynamically
            calculated. The values are meant to enable expression of common
            group or role based access control models, although no explicit
            authorization model is defined. It is intended that the semantics
            of group membership and any behavior or authorization granted as a
            result of membership are defined by the service provider. The
            canonical types <spanx style="verb">direct</spanx> and <spanx
            style="verb">indirect</spanx> are defined to describe how the
            group membership was derived. Direct group membership indicates
            the user is directly associated with the group and SHOULD indicate
            that clients may modify membership through the <spanx
            style="verb">Group</spanx> resource. Indirect membership indicates
            user membership is transitive or dynamic and implies that clients
            cannot modify indirect group membership through the <spanx
            style="verb">Group</spanx> resource but MAY modify direct group
            membership through the <spanx style="verb">Group</spanx> resource
            which MAY influence indirect memberships. If the SCIM service
            provider exposes a Group resource, the <spanx style="verb">value</spanx>
            sub-attribute MUST be the <spanx style="verb">id</spanx> and the
            <spanx style="verb">$ref</spanx> sub-attribute must be the URI of
            the corresponding <spanx style="verb">Group</spanx> resources to
            which the user belongs. Since this attribute has a mutability of
            <spanx style="verb">readOnly</spanx>, group membership changes
            MUST be applied via the <xref target="group-resource">Group
            Resource</xref>. The attribute has a mutability of <spanx
            style="verb">readOnly</spanx>.</t>

            <t hangText="entitlements">A list of entitlements for the user
            that represent a thing the user has. An entitlement MAY be an
            additional right to a thing, object, or service. No vocabulary or
            syntax is specified and service providers and clients are expected
            to encode sufficient information in the value so as to accurately
            and without ambiguity determine what the user has access to. This
            value has NO canonical types though type may be useful as a means
            to scope entitlements.</t>

            <t hangText="roles">A list of roles for the user that collectively
            represent who the user is; e.g., <spanx style="verb">Student, Faculty</spanx>.
            No vocabulary or syntax is specified though it is expected that a
            role value is a String or label representing a collection of
            entitlements. This value has NO canonical types.</t>

            <t hangText="x509Certificates">A list of certificates issued to
            the User. Values are <xref target="type-binary">Binary</xref> and

                  on uniqueness by returning HTTP Response code 400 (Bad

                  to a greater degree than the service provider enforces. For
                  example, a client could make a value unique while the server
                  has uniqueness of <spanx style="verb">none</spanx>. Valid

                      server generated key or counter). No two resources on

        <t>This section defines the process for registering new SCIM schemas
        with IANA. A schema URI is used as a value in the schemas attribute (
        <xref target="schemas-attribute"/> ) for the purpose of distinguishing
        extensions used in a SCIM resource.</t>

        <section title="Registration Procedure">
          <t>The IETF has created a mailing list, scim@ietf.org, which can be
          used for public discussion of SCIM schema proposals prior to
          registration. Use of the mailing list is strongly encouraged. The
          IESG has appointed a designated expert who will monitor the
          scim@ietf.org mailing list and review registrations.</t>

          <t>Registration of new schemas MUST be reviewed by the designated
          expert and published in an RFC. A Standards Track RFC is REQUIRED
          for the registration of new value data types that modify existing
          properties. A Standards Track RFC is also REQUIRED for registration
          of SCIM schema URIs that modify SCIM schema previously documented in
          a Standards Track RFC.</t>

          <t>The registration procedure begins when a completed registration
          template, defined in the sections below, is sent to scim@ietf.org
          and iana@iana.org. Within two weeks, the designated expert is
          expected to tell IANA and the submitter of the registration whether
          the registration is approved, approved with minor changes, or
          rejected with cause. When a registration is rejected with cause, it
          can be re-submitted if the concerns listed in the cause are
          addressed. Decisions made by the designated expert can be appealed
          to the IESG Applications Area Director, then to the IESG. They
          follow the normal appeals procedure for IESG decisions.</t>

          <t>Once the registration procedure concludes successfully, IANA
          creates or modifies the corresponding record in the SCIM schema
          registry. The completed registration template is discarded.</t>

          <t>An RFC specifying new schema URI MUST include the completed
          registration templates, which MAY be expanded with additional
          information. These completed templates are intended to go in the
          body of the document, not in the IANA Considerations section. The
          RFC SHOULD include any attributes defined.</t>
