the BSD license, 3 clause, phohibits usage of the name of the project (JMonkeyEngine, Lemur) and its contributors to promote a derived project w/o permission.
promotion in which way: github’s README.md, which content can be searched thru google? or a youtube promo video?
in my case, I am creating a project that depends on JME and Lemur.
It requires both to work, is a technical reason.
I think I did even worse, I used the letters “…JME” on the project short name’s ending (that composes its URL).
I could just put the libraries or their reference on the project and do not speak about their names at README.md, no problem at all.
I can even change the project’s short name, no problem either.
but is that necessary (concerning github or other opensource host)?
or suffice just not publish ex. a youtube video relating my project to them directly? (despite would have to reference them on the technical info about it)
There’s a difference between crediting a project (i.e., “This project uses jME3”) and using the project to promote your own (“jME developers think my project is awesome!”). The former is a common courtesy and sometimes a requirement to use a library, the latter is both unethical (unless the authors have given an explicit endorsement and permission to publicize it) and forbidden by most licenses (including jME’s).
