    Rules Fest
    Don't forget about the San Jose Rules Fest Oct 2010. It's a 3 day event of talks followed by a one day Boot Camp with separate rooms for Jess, Drools&jBPM, Grind Works and Open Rules. You may attend the talks or the bootcamps or both.

    The Boot Camp will spend the morning introducing the 4 Drools technologies: Expert, Fusion, Flow and Guvnor and will additionally cover what's new in Drools 5.1. We will also discuss the plans for jBPM3, jBPM4 and Drools Flow. The afternoon will be an open floor where you can get time with us core developers for any questions, mentoring or assistance that you would like.

    Thanks

  2. Progress Savvion BRMS[ Go to top ]

    I've recently just done some blogs on the subject of Savvion BRMS, a Progress project, that wraps up Drools BRMS and passes it off as their own work with no accreditation.

    Progress Buy a Bridge in Brooklyn (Savvion BRMS) and make Del Boy Trotter Proud

    Breaking news... Have your vote on what the Drools community should do with it's 30% of the Savvion $49mill Sale

    Breaking news... Progress and Savvion steal candy from a baby!!!

  3. Not doing Drools any favors[ Go to top ]

    Mark -

    Drools is open source. If someone uses it, builds a business around it (whether or not you think the business adds much value), then manages to get people to buy the product (or even the business), then isn't that a good thing for open source?

    Think about all of the companies that have been successful doing this, like RedHat taking the Linux OS and selling it as RedHat Linux (and eventually making enough money from going public to buy JBoss and other open source companies).

    Sure, it would have been nice if someone gave you a giant check too, but this time around you weren't in the right place at the right time.

    You are kind of comparing apples to oranges.  Red Hat does a boat load of development on both Linux and huge value add within RHEL.  That's why you see companies like Oracle "forking" RHEL rather than the Linux kernel itself.

    I agree that this is a +++ for OSS.  Also a huge plus for Drools as it shows there is huge value there.  Although, you do have to scratch your head a little and wonder why somebody would pay so much for a repackager.  Would have been cheaper for them to hire Proctor.

    They must have their reasons. There are other people/companies in the business rule space that focus on rule repository and rule management. They could have chosen one of the other companies.

    Honestly the code isn't itself the biggest factor for acquisition, atleast that's what I've been told by others who evaluate companies for acquisition. Often it's the people in the company and revenue that are bigger factors.

  6. Its not the first to do this.[ Go to top ]

    They are not the first to repackage an opersource product and sell it take IBM RAD (ok they did start eclipse) and thier http server.

    They may not directly contribute but they will increase the skills base which is ultimately beneficial to the prject because some of those people may end up contributing.

     

  7. Drools 5.1 Released[ Go to top ]

    There are different types of upstreamers. For some it's an embedded part of some larger app, where it's "just a library" and the user would never know. While we would like accreditation we know it's now always possible, and it's more important to increase mindshare and skill set and generate adoption. Same for organisations where it's used, behind a firewall, and no one ever knows.

    Then there are others such as Intalio or WSO2 who upstream Drools as a "BRMS" adding some value, both give some nominal acknowledgement, and more recently Intalio has started to involve intself in the community process.

    Both are important and exactly why I push Drools under ASL. We need long term health, for that we need "Drools everywhere". To grow mindshare, ra-affirm our technology and paradigms and get good feedback.

    You might want to read my follow up blog where I explain that even in the case of Progress, it's still good for Drools and the community. However if they are gonna pass our other works  as there own, I think they are fair game for me having a bit of fun.
