Nabu - A Semantic Archive for XMPP Instant Messaging

Instant messaging (IM) has become more and more common these days, and is complementing email and other means of electronic communication. However, due to its heavily context-dependent nature, searching archives of instant messages using only full text search is a tedious task. Also, in contrast to mails, files, and other electronic media, instant messages typically do not feature a unique identifier or location, making it difficult to reference a particular instant messaging conversation. Nabu is a semantic archive for XMPP instant messaging designed to address these problems by implementing a semantic message store, using RDF(S) as its storage format. It is implemented as a server module and will log messages, manage access control to the archives on a per-user basis, and allow other components to observe and annotate messages.
