Reusage and changing of BSD licensed software

| | August 5, 2015

I am developing the CRM software for my company. It is a internal product for the moment but it will be distributed in the future. The product is actually web application. I want to add some javascript plugin that is distributed under the New BSD license (without 3-rd clause). But I want to change some part of the code too. For example I want to remove the link to the project page and to change the layout of some parts of the code.

The questions are:

  1. Can I change the plugin source code
  2. Should I add some links to the developers site or company
  3. Can I distribute my application with integrated plugin

Thank you

    You can change the source code. But you need to leave the original license and copyright statement in place, although you can add your own (in which case the resulting, derivative, work is under both sets of copyrights and conditions).

    If the original license conditions contained any links – you cannot remove those (as that would void the license, and hence your ability to use the original code). If they where in the non-license part of the code – then you can, in theory, change ‘anything’.

    You can (re)distribute the application with the integrated plugin – provided that you comply with the license (which in case of the BSD license says that such a (re)distribution should contain the license, the disclaimer, etc).

    In actual practice you should probably still add some links to the developers site or the company as to the origin of the code. I.e. document where you got it, when you got it and what version was used on what date as the basis. This greatly helps document provenance and future maintenance. And long term means that the value of your work is higher; as it is cheaper/easier to ascertain that you indeed had the rights to do what you did.
