1. Introduction

The XMPP Standards Foundation (XSF) [1] defines protocol suites for the purpose of compliance testing and software certification. This document specifies the 2016 compliance levels for XMPP clients and servers; it is hoped that this document will advance the state of the art, and provide guidence and eventual certification to XMPP client and server authors. Unless explicitly noted, support for the listed specifications is REQUIRED for compliance purposes.

2. Compliance Levels

2.1 Core Compliance Suite

Table 1: XMPP Core Compliance Levels for 2016
Feature Core Server Core Client Advanced Server Advanced Client Providers
RFC 6120 [2] Compliance N/A
RFC 6122 [3] Compliance N/A
Feature discovery Service Discovery (XEP-0030) [4]
Feature broadcasts ✓* Entity Capabilities (XEP-0115) [5]
Server Extensibility N/A N/A Jabber Component Protocol (XEP-0114) [6]
Event publishing Personal Eventing Protocol (XEP-0163) [7]

2.2 Web Compliance Suite

To be considered XMPP web compliant, all line items from the core compliance suite above must be met, as well as all items in this suite.

Table 2: XMPP Web Compliance Levels for 2016

2.3 IM Compliance Suite

To be considered XMPP IM compliant, all line items from the core compliance suite above must be met, as well as all items in this suite.

Stanza Acknowledgements Stream Management (XEP-0198) [19]

2.4 Mobile Compliance Suite

To be considered XMPP mobile compliant, all line items from the core compliance suite above must be met, as well as all items in this suite.

Table 4: XMPP Mobile Compliance Levels for 2016
Feature Core Server Core Client Advanced Server Advanced Client Providers
Session Resumption Stream Management (XEP-0198) [19]
Stanza Acknowledgements Stream Management (XEP-0198) [19]
Client State Indiciation Client State Indication (XEP-0352) [20]
Third Party Push Notifications ✓† Push Notifications (XEP-0357) [21]

* 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.

§ Only one of the recommended providers must be implemented for compliance.

3. Implementation Notes

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

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) [22].

6. XMPP Registrar Considerations

This document requires no interaction with the XMPP Registrar [23].

7. Acknowledgements

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>.
