Welcome to Nabu

Nabu is a plugin for Jive Messenger, a server implementation of the Jabber Instant Messaging protocol. It provides server-side logging of chat conversations and related events. The logged data is stored in a semantic graph, using the RDF W3C standard.

Nabu is developed in context of the EPOS project. The goals of Nabu are:

  • Enable clients to search and annotate their archived conversations. The archive can be searched for messages using the SPARQL query language. Users can annotate messages by adding their own RDF statements, e.g. to classify conversations by topic.
  • Allow listeners (authorized and controlled by the user) to subscribe to the logged events. In EPOS, this is used to identify the context (current tasks, documents, contacts, ...) of a desktop user, to provide optimal support by the desktop environment.
  • Make it possible to share information with other users. For example, share the log of an online meeting with other team members. Privacy is ensured by a strict privacy model, letting the message sender control which other users or user groups can access the archived message.
