Yes, the mechanism is abstract enough to support other datasources. We plan on adding REST resources in the future as another type of external variable. Regarding JBI NormalizedMessage properies, we've been working on a spec proposal for "context" that could hold this kind of information in the process data and carry it between the process and the integration layer (Axis2/JBI/SCA/...). We'll publish something on the wiki very soon to kickstart the discussion. This being said, the best practice for data that needs to be accessed and manipulated within business processes is still to place this information in the message payload, not in message headers or properties. alex
