First draft based on XEP-0443.

+ + +
+ +

+ There is a growing number of XMPP Extension Protocols (XEPs) that provide + different building blocks for XMPP-based applications. XMPP software + developers are confronted with the challenge of finding the right + combination of XEPs for a given application profile. Users need a way to + compare applications without resorting to comparing for individual XEP + numbers. +

+

+ This document defines XMPP application Categories based on + typical use cases (Core, Web, IM, Mobile) and Levels + (Core, Advanced) based on functionality in the respective category. For + each combination of those, the required XEPs are referenced. As the + protocol landscape changes over time, this document is updated roughly + once a year. +

+

+ For developers, this document provides guidance on which specifications + they need to consider when implementing an application of a certain kind. + By completing a compliance test or performing a self-assessment, they can + advertise their implementation as compliant with a given Category and + Level. +

+

+ For users, this provides an easy way to compare implementations based on + their respective advertised compliance levels and year. +

+

+ Unless explicitly noted, support for the listed specifications is REQUIRED + for compliance purposes. + A feature is considered supported if all comma separated feature providers + listed in the "Providers" column are implemented (unless otherwise noted). +

+ +

This section outlines the protocol specifications that are relevant for + developers, but are not ready yet to be required for Compliance. + Developers are encouraged to implement those and + to share their experience and feedback.

+ + + +

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

+ + +

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