Add a license notice as a header of every source files
Activity
changed milestone to %0.7.0
I am planning to add following license notice as headers of every Python files, with on of the three lines:
""" Copyright © 2016-2019 Silkaj, Duniter Copyright © 2016-2019 Moul, Tortue, Jytou, Cebash, Cgeek Copyright © 2016-2019 Maël Azimi, Tortue, Jean-Yves Toumit, Sébastien DA ROCHA, Cédric Moreau Silkaj is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

Edited by MoulCopyright statement (what you call "one of the three lines", I guess) should be represent who claims copyright for which years. Typically (but depending on jurisdiction) a copyright holder is either a) a person contributing creative changes to the work (i.e. the file) that year, or b) a person or organisation paying someone else for their time that year and therefore own whatever creative works those others contributed.
I suggest adding a separate line per copyright holder. Not very important, but avoids ambiguity: Is "Silkaj, Duniter" one or two entities? Do each of them claim copyright for all listed years?
I also wonder if correct that "Silkaj, Duniter" hold any copyright in this project - but you know best :-)
And I suggest to not list someone contributing non-creative changes: Use copyright statements for legalese not for crediting in the social sense of the word: Use a project-wide CREDITS file for socially crediting all contributors (or whomever you want to creedit for whatever reason) independent of legal requirements or intensions.
For copyright statements I recommend to use real names + a single pseudo-unique identifier.
Example:
Copyright 1983, 2019 Jonas Smedegaard <dr@jones.dk>Personally I would use double space to separate range (i.e. the years) from copyright holder. Some use comma (but that is slightly ambiguous - when copyright holder is an organization starting with a number), and some use a single space. Not really important, just style - my parser should handle all styles ;-) https://metacpan.org/pod/String::Copyright
Copyright sign © is superfluous - it predates the Berne convention: https://en.wikipedia.org/wiki/Copyright_symbol - but add it if you like, it is a beautiful glyph :-)
Some worry that email addresses are easily harvested by bots, and try masquerade e.g. replacing @ with space + AT + space. Please don't: Harvesting tools are far more efficient than humans, so what you really do is make it slightly more cumbersome for robots and VERY ANNOYING for humans to use your information.
Some avoid having real identifiers altogether. Then use pseudonymous name and indetifier instead (if legal to do so in your jurisdiction). I believe it is comparable to how it is legal to make a binding contract - you likely need to know who is involved in the deal, but may not (depending on jurisdiction) need to know identities in a way that can be cross-referenced with other identity tables (e.g. a phone book).
