Re: [rules-users] Drools Flow / Declarative process definition

Jaroslav, Yes, if you execute your processes in advanced mode, we are translating procedural constructs like sequence into a more declarative rule like the one you described as an example. Note we are currently not doing that for all procedural constructs (like branch / joins) but we plan to extend these integration points over time. This does allow you to execute a process without having explicit connections between all nodes. We like to describe this as process fragments, where you have small, not-connected flow fragments and where the rules or the user can define when each fragment should be executed, etc. This could then be event-based, data-based, user-triggered, etc. Instead of the process controlling everything, we see this as an inversion where your rules will be controlling the process fragments. This is however still work in progress (meaning a lot is already possible if you dive into it, but we definitely need to extend the tooling etc. to better harness this power before we unleash this to our users). I'm hoping to do a blog entry about this soon, to show some direction. If you're interested in this, it's also related to flexible or ad-hoc processes, adaptible case management, etc. Drools currently targets the Java space primarly. But this doesn't mean you can't use if for XML processing. At this stage, this could become rather complex as we don't provide high-level constructs yet to manipulate this XML data, so you'd have to either build this yourself or do more low-level XML manipulation. As part of our move to BPMN2, we are however planning to seriously enhance this, by adding XPath as a constraint language dialect, better web service integration (as part of our integration with the ESB and the entire SOA platform), etc. Kris ----- Original Message ----- From: "Jaroslav Pullmann" <jaroslav.pullmann(a)fit.fraunhofer.de&gt; To: <rules-users(a)lists.jboss.org&gt; Sent: Friday, February 26, 2010 2:47 PM Subject: [rules-users] Drools Flow / Declarative process definition Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
