Parents and kids

Collaboration in the Sugar sense is simply helping kids play together. Kids play together all the time. They talk, they run, they throw balls back and forth. Sugar allows kids to talk and play and learn together.

Activities - Activities, in the Sugar world, are the programs and applications on which kids learn.

Really, that is all you need to know:)

Activity Developers

Presence Service - The Presence Service is a set of APIs which allow developers to enable collaboration features on Sugar.

That is all you need to know. The rest is under the covers.

Core Sugar Developers

Telepathy - Telepathy is another set of APIs which has a 'plug-in' design so that various communication protocols can be 'plugged-in' without affecting what the user of activity developers sees.

Collaboration Developers

Telepathy-gabble - Telepathy-gabble is a plug-in backend that uses the XMPP protocol to talk to a server.

XMPP - Extensible Messaging and Presence Protocol (XMPP) is an open, XML-based protocol originally aimed at near-real-time, extensible instant messaging (IM) and presence information. (buddy lists)

XMPP Server - At the bottom to the stack is a XMPP server. These are often referred to as jabber servers because the first popular XMPP Server was called jabberd.
