1. Introduction

The XMPP Standards Foundation (XSF) [1] defines protocol suites for the purpose of compliance testing and software certification. This document specifies the 2012 compliance levels for XMPP clients and servers. [2] Unless qualified where explicitly noted, support for the listed specifications is REQUIRED for compliance purposes.

2. Compliance Levels

Table 1: XMPP Compliance Levels for 2012

Spec Core Server Core Client Advanced Server Advanced Client
RFC 6120 [4]
RFC 6121 [5]
RFC 6122 [6]
Service Discovery (XEP-0030) [7]
Entity Capabilities (XEP-0115) [8] ✓ *
Jabber Component Protocol (XEP-0114) [9] N/A N/A
Blocking Command (XEP-0191) [10]
BOSH (XEP-0124) [11] ✓ **
XMPP Over BOSH (XEP-0206) [12] ✓ **
vcard-temp (XEP-0054) [13]
Personal Eventing Protocol (XEP-0163) [14]
Multi-User Chat (XEP-0045) [15] ✓ ** ✓ ***
Chat State Notifications (XEP-0085) [16] N/A N/A
Message Delivery Receipts (XEP-0184) [17] N/A N/A
Stream Management (XEP-0198) [18]

* Necessary to support Personal Eventing Protocol (PEP).

** Support can be enabled via an external component or an internal server module/plugin.

*** Support for the Entity Use Cases and Occupant Use Cases is REQUIRED; support for the remaining use cases is RECOMMENDED.

3. Implementation Notes

Some of the protocol specifications referenced herein have their own dependencies; developers need to consult the relevant specifications for further information.

Developers are advised to refer to Best Practices for Use of SASL EXTERNAL (XEP-0178) [19] regarding proper implementation of the SASL EXTERNAL mechanism in XMPP.

4. Security Considerations

This document introduces no additional security considerations above and beyond those defined in the documents on which it depends.

5. IANA Considerations

This document requires no interaction with the Internet Assigned Numbers Authority (IANA) [20].

6. XMPP Registrar Considerations

This document requires no interaction with the XMPP Registrar [21].

7. Acknowledgements

Permission is hereby granted, free of charge, to any person obtaining a copy of this specification (the "Specification"), to make use of the Specification without restriction, including without limitation the rights to implement the Specification in a software program, deploy the Specification in a network service, and copy, modify, merge, publish, translate, distribute, sublicense, or sell copies of the Specification, and to permit persons to whom the Specification is furnished to do so, subject to the condition that the foregoing copyright notice and this permission notice shall be included in all copies or substantial portions of the Specification. Unless separate permission is granted, modified works that are redistributed shall not contain misleading information regarding the authors, title, number, or publisher of the Specification, and shall not claim endorsement of the modified works by the authors, any organization or project to which the authors belong, or the XMPP Standards Foundation.

Disclaimer of Warranty

## NOTE WELL: This Specification is provided on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. ##

Limitation of Liability

In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing, shall the XMPP Standards Foundation or any author of this Specification be liable for damages, including any direct, indirect, special, incidental, or consequential damages of any character arising from, out of, or in connection with the Specification or the implementation, deployment, or other use of the Specification (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses), even if the XMPP Standards Foundation or such author has been advised of the possibility of such damages.

IPR Conformance

This XMPP Extension Protocol has been contributed in full conformance with the XSF's Intellectual Property Rights Policy (a copy of which can be found at <http://xmpp.org/about-xmpp/xsf/xsf-ipr-policy/> or obtained by writing to XMPP Standards Foundation, 1899 Wynkoop Street, Suite 600, Denver, CO 80202 USA).

Appendix D: Relation to XMPP

The Extensible Messaging and Presence Protocol (XMPP) is defined in the XMPP Core (RFC 6120) and XMPP IM (RFC 6121) specifications contributed by the XMPP Standards Foundation to the Internet Standards Process, which is managed by the Internet Engineering Task Force in accordance with RFC 2026. Any protocol defined in this document has been developed outside the Internet Standards Process and is to be understood as an extension to XMPP rather than as an evolution, development, or modification of XMPP itself.


Appendix E: Discussion Venue

The primary venue for discussion of XMPP Extension Protocols is the <standards@xmpp.org> discussion list.

Discussion on other xmpp.org discussion lists might also be appropriate; see <http://xmpp.org/about/discuss.shtml> for a complete list.

Given that this XMPP Extension Protocol normatively references IETF technologies, discussion on the <xsf-ietf@xmpp.org> list might also be appropriate.

Errata can be sent to <editor@xmpp.org>.


Appendix F: Requirements Conformance

The following requirements keywords as used in this document are to be interpreted as described in RFC 2119: "MUST", "SHALL", "REQUIRED"; "MUST NOT", "SHALL NOT"; "SHOULD", "RECOMMENDED"; "SHOULD NOT", "NOT RECOMMENDED"; "MAY", "OPTIONAL".


Appendix G: Notes

1. The XMPP Standards Foundation (XSF) is an independent, non-profit membership organization that develops open extensions to the IETF's Extensible Messaging and Presence Protocol (XMPP). For further information, see <http://xmpp.org/xsf/>.

2. The XSF neglected to publish compliance suites for 2011; therefore the predecessor to this document is XMPP Compliance Suites 2010 (XEP-0270) [3].
