Legal aspect of using free libraries and cms for development?

Question

CMS

Does anyone have experience with the subject?
Suppose we develop a site under a contract, by default in layout we use jQuery and, for example, Wordpress for cms, while according to the civil code we create an object protected by copyright (a computer program), and we must have rights to it (for example, transfer a non-exclusive license to a client) in order to he could use it stupidly.
There is a legal collapse, even if we write that the result of the work of the executor may contain computer programs of third parties, then we should, as it were, guarantee the legality of using these programs, since the MIT license will not be of interest to anyone in case of any problems, any ideas?

Answer 1

There is no legal collapse. You create not just a program, but a composite work that includes programs of other authors. In your case, the composite work is burdened with additional terms imposed by open source licenses.
Personally, I would recommend attaching the original licenses in the source code and draw the attention of the client to this. In the very text of the agreement, it is necessary to distinguish between the fact that for such and such parts of the work the exclusive right is transferred, and for such parts - the right to reproduce and other rights that a specific license provides. The license itself is not worth mentioning, as well as quoting from it.
After that, the lawyers and the client's accounting department will slowly go crazy, but you will be clear before domestic law and open licenses.

Answer 2

Depends on the license of the programs used. If LGPL, then just dynamically link, and in the folder with the program a file with an LGPL license. If BSD or MIT, then you can even assign like.

Answer 3

The easiest way, if you don’t want to understand the compatibility of licenses between yourself and our legislation, is to “force” the client to download jQuery and WordPress himself, and transfer only his code and his license with integration instructions to him. For our "organs" this should be enough.

Answer 4

You can do it like in Quake, they simply indicated that the rights to the game itself belong to the ID, and to some parts of the engine (for example, the ZIP algorithm) - to their developers.
