With the news of Rapid-I now being RapidMiner we thought it would be helpful to reiterate that the core of RapidMiner stays open source.  And exactly like for previous versions of RapidMiner, we extend this core and offer this extended functionality only to our customers.  Following this approach, the commercial editions of RapidMiner 6 will better scale up for the analysis of larger data sets and offers more connectors to data sources.  At the same time, RapidMiner will change its model to business source, which means that older versions of the software are available under a OSI-certified open source license while the latest version, although still open source for most parts of the product, will only be available as a trial version or under an commercial license.

With every new major version, the newest major version and its updates will be available under this business source license while the previous versions will be licensed under the AGPL v3 just as before.  This business source approach offers many of the benefits of an open source model and we consider it superior to the open core model which we have been using so far since the open core model does actually not offer any of the advantages of an open source license to our customers.

    This is not an honest approach. You should have changed the name to something new not the version number. This is deceit.

    I have never heard of such transition from open source to commercial in the middle of nowhere.

    Furthermore I will never trust in such a mindset in any commercial affairs.

      Dear John,
      Thanks for taking the time to write and share your thoughts. There are a lot of things happening at once and I am sure it can seem overwhelming.
      The new version of RapidMiner is still the same great basic product but there have been several enhancements, so a new version number was appropriate.

      The transition to a business source model was not taken lightly, and we’re working closely with our advisors and other members of the community to do so in an open and transparent fashion. One such advisor is Monty Widenius, the main author of the original version of the open source MySQL database.

      Multi- or dual-licensing is not uncommon in the software industry. MySQL is just one example of this. MySQL Enterprise Edition, Standard Edition and Cluster CGE are commercial editions and can be purchased. The other editions, such as the MySQL Classic Edition or MySQL Community Edition, are free to use although some restrictions apply. Monty has done a great job explaining his updated thinking on open source versus business source. You can read his blog here: http://monty-says.blogspot.com/2013/06/business-source-software-license-with.html

      We believe that the transition is necessary to support RapidMiner and the RapidMiner community over the long term. Unlike most open source products, the RapidMiner core was produced entirely by the team at Rapid-I (now RapidMiner). We know we need to continually invest more in the product.

      Many software vendors use open source frameworks, modules, and libraries inside their commercial products and services. Many customers are willing to pay for the benefits of a commercial product – things like legal protection, commercial-grade quality assurance, and professional support/training/consulting. Those paying customers allow us to further invest in the product for the benefit of the whole community, and yes, grow a company that can support the product over the long run.

      I hope this helps to better explain what we are doing. Thanks again for taking the time to write.

      Best regards,

    This has been a fantastic way to alienate your entire user base. Given the number of viable, open source, free alternatives, it’s easy enough for most to just switch. If I wanted a subscription product, I would just use SAS enterprise miner. What’s worse though, is that this sort of change should have been communicated to your users well in advance. To make such a change midstream without any notification was a serious blunder. Additionally, your site, blog, etc have become opaque marketing and sales nonsense. I realize you need to earn revenue one way or another to support your products, but you’ve switched business models and it seems the entire culture of your firm in an abrupt and significant way that can and will be problematic for many of your users. At this point, I’m transitioning away from RapidMiner in my production systems and will no longer recommend others rely upon it not because costly, but because I don’t feel that I can trust the company supporting it to keep me informed and allow ample planning time for major changes such as this.
