1. Write in front
I participated in the open source annual meeting held by the Open Source Society last weekend. I hosted the open source governance sub-forum on the afternoon of the first day. The BSL license translates it a bit. If I hadn't seen the photo of Peng Lixun and Monty at Shaolin Temple in the circle of friends just now, I guess I could still drag it. . . So the beginning of the following article was written half a month ago.
In mid-October, Michael Monty Widenius came to the platform of Yunqi Conference for the third time, and once again promoted MariaDB, but this time he changed the PPT. The only thing missing from Ali Technology's GitHub is his theme PPT. I only saw the video on the Internet, which made my obsessive-compulsive disorder very uncomfortable. It has only been a few days since Ali announced the news of the investment in MariaDB Corporation. Taking advantage of this hot spot, I just wanted to simply write Maria's BSL license, turn on the computer and organize the data, and my thoughts were freed, and I found out about Monty's personal development. Isn't history the history of open source software development, from MySQL to MariaDB, from MySQL AB to MariaDB Corporation, the attempts to grow and be acquired, to split and commercialize, it's exciting to think about it. I was prepared to write the first draft in two hours, but I was troubled by the MySQL code and MariaDB code. I didn’t know where to start, and it took me a day to read the information. The communication between the experts was a little enlightened, but fortunately, write whatever comes to mind.
2. BSL license introduction
The first part introduces the delayed open source model of MariaDB Corporation and its BSL license (you have to distinguish between MariaDB Foundation and MariaDB Corporation, although the staff of the two overlap, but they are two different organizations). In August last year, MariaDB Corporation announced that it would use the BSL license (Business Source License) on MariaDB MaxScale, which caused a thousand waves, and the community commented, good and bad, so what exactly is BSL? What exactly is the delayed open source model that monty is talking about? The following is my translation of BSL1.1.

3. Example
You may not understand just by looking at the license. I will show you the license file of MariaDB. The address is: https://github.com/mariadbcorporation/MaxScale/blob/2.1/LICENSE.TXT.
I just started writing in Open Source China recently, and some subsequent articles will be posted here, mainly in several directions: open source software legal risks, license compliance, business models, and collaboration models. I will also translate some foreign works. Based on the principle of being short and powerful, I will eat less and eat more meals . I hope everyone likes it, and you are welcome to make a brick. Thanks for the support
