Modern XMPP is an independent project launched to improve the quality of user-to-user messaging applications that use XMPP. XMPP is a mature open standard for internet messaging. If you are reading this, you have probably heard of it.
We are developing a handful of simple documents aimed at people who wish to build on top of XMPP. The recommendations are derived from healthy discussions between developers from multiple XMPP projects and other members of the XMPP community.
Our recommendations highlight only the XEPs you need to implement for a modern messaging application, ignoring historical cruft and excessive backwards-compatibility.
We also intend to provide a comprehensive set of guidelines for UI and UX design. Developing a client was never just about the protocol. In fact in most cases the protocol is a secondary concern. Having a concrete set of guidelines will help to provide a more uniform user experience between different applications, ensuring they use the same terminology, and provide interoperable feature sets.
