A new release of JRules just came out. Sadly the name changed, for Operational Decision Management. The components are also renamed, it may be to do not confuse the new product manager, who is also responsible of IBM BPM. Therefore Rule Studio is now Rule Designer, and Rule Team Server is named Decision Center, RES new name is Decision Server. The following diagram illustrates the new components.
The big change in this release, is the event filtering rules as part of the product. The Event Designer is an eclipse plugin, as Rule Designer is. It is a port of WBE development environment into eclipse and the filters are also managed within the decision center. This is very important to have one platform to govern all the authoring and deployment of rules and filters.
