Open source license issue

Get Started

Hello,
I would like to distribute a Python script (with JavaScript/CSS and third libraries as jQuery, Bootstrap) under a free license, but I have some questions:

  1. Should I indicate the license in all files or a single text file with the license in the root of the software enough?

  2. Should I indicate the date in the license and why?

  3. Can I put the text of the license under another license (e.g. Attribution-ShareAlike 3.0)?

Thank you.

Can you answer me, please?

You can if you want but don’t have to. A simple LICENSE file is enough.

  1. Should I indicate the date in the license and why?

Date of what? You don’t have to date anything.

  1. Can I put the text of the license under another license (e.g. Attribution-ShareAlike 3.0)?

Maybe…but why? why license the license that doesn’t make much sense…
Unless you mean this: https://en.wikipedia.org/wiki/Multi-licensing

@logic_earth Thank you very much for your response!

Here’s an example

“Copyright (C) <year> <last name> <first name>”

The year is it mandatory for the license to be valid (legal)?

That is copyright stuff, nothing to do with a license. But no, there is no mandatory…aspect of it. Nor do you even need to put “copyright” anything.
