Perhaps part authors need to do more thinking and talking about this. I
must admit my eyes start to glaze over when terms like zlib, GPL and other
legalese are tossed about, but whatever we do will likely have impact on
the future of the parts library project.
Here are some thoughts that are rolling around in my head:
1. Derivative works:
In a situation where someone uses my parts in an LCad program to create a
model and make pretty pictures of it, I don't want to restrict in any way
their claim to copyrights of those pictures or even the model file (as
long as use of that model file needs the parts library to be viewed.)
If that person were to distribute their model in a way that the parts
library was not needed (for example inlining all the parts) then the
information about the authorship of the parts should be included in such a
distribution.
Any application which transforms the parts library (i.e. LeoCAD, some VMRL
converter, or L3P) should also include information about part authorship.
I know L3P does this nicely, what about LeoCAD?
2. Commercialization of parts library:
I'm a bit ambivalent about this. On the one hand, I want the parts to be
used as widely as possible, provided they give proper credit to authors.
I like the idea that some of the programmers who have contributed here
would turn LCAD into a commercial success.
At the same time, I'm a little troubled at the thought that I would have
to pay money to use a product that is completely reliant on the thousands
of combined hours I and other authors have put into the parts library.
I'm not quite sure what effect that would have on authors' willingness to
make future contributions.
Can any of you who understand these licenses comment on how they would
relate to the above concerns?
Do other authors have similar concerns, or others?
