Extensible Messaging and Presence Protocol (XMPP)


XMPP (Extensible Messaging and Presence Protocol) is a messaging protocol for products based on XML. It provides online access to messaging of extensible data of different types among a few or more XMPP entities in one network. It is widely used in software development companies like VEProf for messaging applications.

The first name of the protocol was Jabber, and it was created in 1999. It was made by Jabber open-source community for instant messaging possibility, presence info, and availability and control of a contact list. Originally designed and developed as an extensible technology, XMPP has served for sharing files, making voice or video calls, regular chat, public subscribe notification, IoT apps of different kind, games, and social networks.

XMPP is a special technology mostly because it is open to anyone, and it is extensible enough and ready for cooperation, which makes it an incredible foundation for any XMPP based implementation that a person or a company can create. It is developed as an open source project. It can work with any software license. It is one of the best and user-friendly protocols available, though there is a great variety of clients and libraries that are also open-source and accessible. When it comes to XMPP, its main advantage is it can be customized, and individuals or companies can develop their own extension, depending on their purpose.

In 2002, the Internet Engineering Task Force gathered a working team on XMPP to make XMPP an official instant-messaging and presence technology. In 2004, they released specifications, known as RFC 3920, RFC 3921, RFC 3922, RFC 3923. Later, XMPP became an open-source standard. These specifications were upgraded and rethought and fixed in 2011, creating RFC 6120, 612,1 and RFC 6122. In 2015, they created RFC 7622. These extensions are available for work, and XMPP experts are continuously working on expanding the possibilities of XMPP technology, making it more secure and advanced.

XMPP Standards Foundation reported, by 2003, more than 10 million people were using XMPP technology, and since then, the number has risen.
