Drools 5.x was not designed to be thread-safe in general: there are some known critical races that may arise when multiple threads are inserting facts in parallel. Many have been patched in 5.6, but the real solution to the problem will be introduced in the 6.x series.

My goals are to be able to receive data from any data source, translate it to triples (as much as I can see, any kind of data source is feasible to be translated into triples: relational, NoSQL, XML, etc). Then, given that input triples, infer as much meta data as possible, for example, infer types/classes without any schema information and then build a meta model with this translate-able model to other output models or endpoints. The idea of MDAfy is still fascinating. Maybe, I'm not sure, this could work with Drools in this way: My model has a set of predefined entities which represents semantic / semiotic relationship. Having a set of 'predefined' rules in Drools for each kind of entity for which the meta model provides 'executable' instances, for me sounds like some kind of meta programming that could be done. Drools could be the engine and the meta model and input data could be kind of script. I'm really not sure if something like this could be done, I'm just thinking out loud. Best regards, Sebastian.

Currently the project vs product version numbering is considered confusing by some people; especially when both the project and the product are on the same major version number. One of the ways JBoss wishes to address this is for the community major version to automatically increment just prior to the product release - if the community is on the same version. For example as JBoss BRMS 6.0 is about to release, with community currently also on 6.0 the next community release would be required to move to 7.0, instead of 6.1. Community can then do 7.1, 7.2, 7.3 etc until the product shifts to 7.0. At which point the community much shift to 8.0.

The problem is the node sharing of Foo2. R1 thinks it?s propagating an update, when it never passed R1?s Foo2 before, so it should propagate as an update for R2 but an insert for R1. I suspect the problem is related to the SegmentPropagator when it is updated after moving from the first shared segment, to the two child segments. Please try to avoid submitting project jars. It takes a lot more time for us to setup and work with, which will delay our time in getting back to you.
