It is a Java-based open source visual development platform allowing to automate business processes and connect heterogeneous applicative systems.
It has a graphical user interface for process modeling and debugging.
The dynamism/intelligence of the processes is expressed through (essentially) Java code snippets, which eliminates the need to learn any specific syntax.
Extensibility is almost a key feature allowing any user to model and mostly generate plugins complementing core features as needed.
