Apache Unomi is a REST server that manages user profiles and events related to the profiles. It can be used to integrate personalization and profile management within very different systems such as CMS, CRMs, Issue Trackers, native mobile application. It was designed to be easy to integrate with external systems, promoting profile sharing and re-use in very different applications. Basically the server tracks users using different mechanisms (by default cookies), builds a progressively populated profile and associates events that are performed by a user with his profile. Events may range from a click on a page, to a file being downloaded, a native mobile application button being clicked, or anything that can be sent to the server.
