1. Introduction

The XMPP Standards Foundation (XSF) [1] defines protocol suites for the purpose of compliance testing and software certification. This document specifies the XMPP Basic Server 2008 certification level.

2. Definition

The XMPP Basic Server 2008 certification level is defined as follows:

Table 1: Required and Recommended Specifications
Specification Requirement Level
Service Discovery (XEP-0030) [4] REQUIRED
Non-SASL Authentication (XEP-0078) [5] RECOMMENDED *
Error Condition Mappings (XEP-0086) [6] RECOMMENDED *
Stream Compression (XEP-0138) [7] RECOMMENDED

* Note: Support for XEP-0078 and XEP-0086 is recommended for backward compatibility only. It is likely that compliance definitions for future years will remove these recommendations.

3. Implementation Notes

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

Developers are advised to refer to Best Practices for Use of SASL EXTERNAL (XEP-0178) [8] 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) [9].

6. XMPP Registrar Considerations

This document requires no interaction with the XMPP Registrar [10].

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.
