I have recently posted about a demo project I implemented in Mercury (
as seen there licensed under the MPLv2.
Recently a kind gentleman has followed up on my mail, being interested in
additional material related to it.
This gentleman has introduced himself and briefly talked about his
interests and what he did during his work life.
I was pleasantly surprised to hear about a fellow practitioner also using
One of the areas of work was patent law, which didn't surprise me at first.
However, after some time it got me thinking and thought briefly about
whether I correctly stated all references,
gave credit where credit is due, etc. whether I behaved ethically correct
in regards to publications and so on,
which every academic should do of course.
However, another thought came to mind and I thought about the license of my
I have deliberately chosen a license which would promote sharing of
modifications that could prove useful to the general public,
while not being too restrictive, hence why I licensed the demo project
Most of my other open-source projects have been developed in Java, which is
licensed using the GPLv2 with the classpath exception
which I assumed was true also for Mercury.
The freedom of licensing your source code however you want, is what I
fundamentally assume(d) is true for every programming language in the world!
However, after checking Mercury's GPLv2 License there was no such exception.
Am I being paranoid here, did I misunderstand the license, or did I
inadvertently cause copyright infringement?
Should my demo project's license be actually Mercury's license?
I'm usually very pedantic and correct when it comes to "these" kinds of
things, but am currently very dumbfounded and certainly not an expert,
I would appreciate any help / answer you could give me
(Also apologies to the gentleman for describing the specifics of our
conversation, I hope you don't mind, it just illustrates my thinking
(Furthermore, I think the answer to this question could maybe prove useful
for other people who search for it too)
