From this humble basis, it has been used to build large-scale instant messaging systems, Internet gaming platforms, search engines, collaboration spaces, and voice and video conferencing systems. More unique applications appear every day, further demonstrating how versatile and powerful XMPP can be.
XMPP is made of a few small building blocks, and on top of these primitives many larger constructions have been made. Within XMPP are systems for building publish-subscribe services, multi-user chat, form retrieval and processing, service discovery, real-time data transfer, privacy control, and remote procedure calls.
