NxBRE is now licensed under the MIT License, the LGPL license was creating issues for some users.
After many years of waiting, RuleML 1.0 has finally been announced: http://ruleml.org/1.0/
It was one of NxBRE's Inference Engine original goal to follow the RuleML versions until 1.0 will be reached. Though I'm not in the position to announce any ETA for supporting it, it's definitively a feature that will be added: http://sourceforge.net/tracker/?func=detail&aid=3053861&group_id=97759&atid=618998... read more
I'm happy to announce the release of a new version of the Inference Engine Console.
It's a minor release with two new features, including one kindly contributed by a user:
* Prompt user for strictness when loading a Visio rulebase (feature request 1812990).
* Support custom queries in HRF format (contributed by Martin Wickett).
RuleML 2009, the International RuleML Symposium on Rule Interchange and Applications, will be held in Las Vegas, Nevada, USA on Nov 5-7, 2009.

Happy new year and happy new NxBRE too!
This new version contains a few bug fixes and the embryo of a backwards-chaining wrapper for the flow engine.
See the release notes for more information: https://sourceforge.net/project/shownotes.php?group_id=97759&release_id=651713
The Flow Engine is currently under work: I have added a simple backward chaining scheduler that can execute sets in order to produce a specified goal in the rule context.
This will allow to better support Reaction RuleML, hence to be able to consume the output of Acumen's RuleManager ( http://www.acumenbusiness.com/Products.htm ), an excellent tool for BRE related development on the .NET platform.... read more
I will be attending SD West 08 next week: if you want to meet and discuss NxBRE, shoot me an email!
I am happy to announce the release of NxBRE 3.1.1. This is mainly a service release for the Inference Engine, which got some bug fixed and simple features added.
See the release notes for more information: https://sourceforge.net/project/shownotes.php?group_id=97759&release_id=566445
Do you feel like running a few minutes remote demonstration of what you have accomplished with NxBRE and RuleML in your project?
Then you are up to the challenge: http://2007.ruleml.org/index-Dateien/Page787.htm
Please contact me ASAP (firstname.lastname@example.org) for more details!
The console has simply been recompiled with the latest version of NxBRE.
Though still very crude, NxDSL can already help you to build a rich rule language for your business domain.
Your feedback will be very appreciated...
Check the release notes to see all the changes: http://sourceforge.net/project/shownotes.php?group_id=97759&release_id=536905
Thanks to everyone for the great feedback, patches and improvement requests!

This second beta release shows no progress on the integration of RuleML 0.91, as some uncertainty in the support of integrity constraints in Naf Datalog remain.
The "smart implication scheduler", which was introduced in v3.1.0Beta1 and was proven dumb, has been rolled-back: the Inference Engine should now behave exactly like v3.0.0.
Many improvements and bug fixes have been included, thanks to the feedback from you, the NxBRE community!
Want to share your experience with NxBRE and RuleML?
Then why not considering a visit to RuleML-2007 that will happen in Orlando, Florida in October (25-26). You might even want to submit a paper or a demo: if that is the case, act fast!
While the construction of version 3.1.0 progresses steadily, thanks to great suggestions and patches from the community, a little set of NxBRE goodies were born!

The patch for bug 1632463 (http://sourceforge.net/tracker/index.php?func=detail&aid=1632463&group_id=97759&atid=618995), ie. "Infinite loop in <While> block", is available in SVN trunk under revisions 202 and 203.
This beta release is intended for those interested in testing one of these two new features:
* Added regex matcher operator (feature request 1545354).
* Improved implication scheduling in the agenda to limitate the number of fired implications (feature request 1590017).
There is also a *preview implementation* of the RuleML 0.91 Naf Datalog adapter. So far, this implementation does not support the cool features of the new version of RuleML (multiple named rulebases in one rule file, retract operations), hence it is not worth using it.
In order to figure out what is planned for the next release, simply check the different trackers (bugs, feature requests): the ones tagged at priority 9 will be included in the next release.
To see what has actually been done and is available in the SVN trunk, turn to the readme file: http://nxbre.svn.sourceforge.net/viewvc/nxbre/trunk/NxBRE3/README.txt?view=markup
The IEConsole has been migrated to .NET 2 and NxBRE 3 (feature request 1598242).
Download it from there: http://sourceforge.net/project/showfiles.php?group_id=97759&package_id=111399&release_id=464405
Finally, after weeks of refactoring, a general beefing up of the documentation, version 3.0.0 is officially out! Check the readme file for discovering the extent of what has been done between version 2.5 and version 3.0.
Please note that branch 2.5 will still be maitained "for a while" but in a minimal way: only patches but no new release.
I am happy to announce the second release candidate of NxBRE v3, which should be the last one before the final 3.0.0 release.
Please check the change log at this URL: http://sourceforge.net/project/shownotes.php?group_id=97759&release_id=440610
The main changes consist in a faster/simpler internal fact base and the introduction of RuleML features already available in v2.5 to Visio 2003 rule bases.
I am happy to announce the first release candidate of NxBRE v3.
Though it satisfies all unit and acceptance tests of NxBRE v2.5.3, this version is not (yet) intended for production but to receive feedback from developers and users.
No new feature has been added but many many changes have been made. Please consult the release notes to discover what and read the README.txt document for a short migration guide.
