Citadel (Groupware)

Encyclopedia : C : CI : CIT : Citadel (Groupware)

Citadel is a messaging and collaboration platform. While other types of groupware focus on automating business processes, Citadel focuses on connecting communities of people together.

History

Citadel was a Unix BBS system in the 1980's. It has since then evolved in the internet age to become a full-featured collaboration suite.

The \"rooms\" concept

A Citadel system is made up of containers called "rooms." A room may be used as an email folder, a discussion forum, a real-time chat, a mailing list, a calendar, an address book, an RSS sink ... and sometimes a combination of any of the above. Furthermore, you can replicate rooms between multiple Citadel nodes, allowing you to set up a federated, distributed messaging environment.

Citadel includes capability for:

Standards-compliant e-mail (POP, IMAP, SMTP)
Shared calendaring (GroupDAV, Aethera, and Kolab-1)
Shared address books
Discussion forums
Instant messaging
Collaborative whiteboards
Bulletin Board System (BBS)

The Citadel system provides numerous front ends to present to users, such as a text-based interface, a web-based interface, and many popular PIM clients using SMTP/POP/IMAP. All of these can be used simultaneously.

It's also scalable. Not only can a well-equipped Citadel server support a large number of concurrent users, but you can also build a distributed network of Citadel nodes that share rooms and their content.
