Hello! I’m about to be finished with a program and wish to publish it on Gitlab as an open source program. Before proceeding, i wanted to know if there is any regulation regarding publishing code using CVB drivers and .dll. Also would like to know what licensing do you recommend. Best regards, Pierre-Olivier Morin ---

Hi Pierre-Olivier! I’m very sorry for keeping you waiting so long! There are two things that might be of interest here. Number one is the CVB License agreement which you can download here: [CVBLicenseAgreement.zip](https://forum.commonvisionblox.com/uploads/commonvisionblox/original/1X/116873c12151de940929b91d677d0afa8865b09e.zip) (1.9 MB) - ignore the registration bit on page 1, page 2 and 3 show the license terms. The other thing to keep in mind is that there are in fact a few Open Source components in use inside :cvb: and applications built on top of :cvb: should declare the use of many of these to avoid violating their license terms. The full list of these components and their respective license terms is available here: [https://help.commonvisionblox.com/NextGen/OpenSourceLicenses.pdf](https://help.commonvisionblox.com/NextGen/OpenSourceLicenses.pdf) This information will also be installed as a \*.chm and \*.pdf file into the _%CVB%\Doc_ directory every time you install :cvb:. As far as code containing calls into the :cvb: library is concernced we do of course not impose any restrictions - after all it’s **your** code and the terms under which you give permission to use it is up to you. ---

Thanks a lot for your answer it helps a lot! hopefully, the program will soon be on gitlab.
