Publish/subscribe communication is increasingly often the basis for distributed, event-based, and loosely-coupled applications. With this communication paradigm, application components communicate indirectly by publishing notifications and by subscribing to those notifications of interest. To precisely specify the subscribers' interests, content-based publish/subscribe systems provide expressive filter models that, on the one hand, ease implementing versatile and entangled interaction patterns. On the other hand, however, resulting notification flows evolve dynamically and implicitly making an analysis the more challenging and complex.
