Hello, you seem to be drafting (possibly along with other people) a new license that you propose for documentation. Even before commenting the details of the license text, I would like to express my own personal opinion on the operation itself. My personal recommendation is: please, don't. License proliferation is harmful, and adding another newly drafted license to the already excessively long list of existing licenses should be avoided, unless absolutely necessary. Writing a good license text, avoiding all the subtle pitfalls that may cause unexpected results, is a very hard task: even legal experts may spend a very long time and yet come up with a flawed text. The use of existing, well-known and well-vetted licenses is highly recommended. Moreover, you are proposing a license specifically designed to be applied to documentation only. This is a poor choice, because the boundaries of what is exactly "documentation" are not so well-defined as one might think. In my own personal opinion, a good license should applicable to any kind of software (in the broad sense of the word, see my [essay] on the topic, for more details). [essay]: <https://www.inventati.org/frx/essays/softfrdm/whatissoftware.html> You are searching for a good simple and permissive license that can be applied to documentation. My recommendation is: if you are writing documentation for a specific program or library, use the same license as the program or library itself. This allows anyone to transfer material back and forth between the program or library and the documentation without having to ask for additional permissions (for instance: material from the documentation may be used to enhance the online help of a program or the comments in the source code of a library, and vice-versa). In the case of DPS8M, I seem to understand that the majority of the code is under the [ICU license], which looks perfectly OK for documentation as well (and meets the DFSG). [ICU license]: <https://gitlab.com/dps8m/dps8m/-/blob/505ed98481766ac936cf0b5ff8de04abd7547f08/LICENSE.md#dps8m-simulator Otherwise, if you are writing general documentation about many different programs/libraries or about other topics (science, art, ...), a simple permissive license that I would recommend is the [Expat] license or the [zlib] license. [Expat]: <http://www.jclark.com/xml/copying.txt> [zlib]: <https://www.zlib.net/zlib_license.html> [...] > Thank you, Thanks to you for asking for advice! I hope my reply may be helpful. -- http://www.inventati.org/frx/ There's not a second to spare! To the laboratory! ..................................................... Francesco Poli .
