VIA offers a visual design environment, with a graphic interface you can use for building SIS components (triggers, compositions, interceptors, and macros).
As explained in SIS Overview and Concepts, the SIS-internal representation of these components are XML descriptor files. With VIA, instead of producing or maintaining this XML manually, you can create the SIS components visually as diagrams (such as trigger diagrams and interaction diagrams). VIA takes over the task of generating the XML descriptors so you can focus on the task of defining service interaction behaviour, rather than writing XML.
The following screenshot shows key components of the VIA GUI.
