Well, the intent is clear in both the wording of the QPL 6 header as well as the Trolltech annotations. I don't know if the ocaml upstream realize that, i think that maybe not, but i will get clarification from them about it. > (or ...) from c3 and c4. Similarly, the reverse for c3: especially, I Err, you mean QPL 3 and QPL 4 here ? prefixing the clauses with the licence is good practice, since it precludes confusion between QPL 3 and DFSG 3 for example. > think about modifications which turn part of ocaml into a linked (but > seperate) reusable component. What did I miss? The clear distinction trolltech has put into the QPL licence wording and the annotations ? Also the QPL 6 header clearly makes a separation between the "application programs, reusable components and other software items that link with" and the "original or modified versions of the Software". I am no lawyer, but i am under the impression that the intent of the licence writter comes into play when there is dubious interpretation, but the number of times this distinction is made in the licence doesn't let much doubt about the interpretation. > >The upstream author can request a copy of the items, if they are > >distributed, > >but not openly distributed (in which case he just needs to get the > >public > >version).

I don't follow you, the author of the work linking with the original software is free to chose any free licence, BSD or QPL, and it doesn't say anywhere that you have to make particular consesion for the upstream author. The only thing QPL 6c ensures is that you cannot refuse to distribute the linked software to the upstream author, if you distribute it to other folk under the QPL 6. > As I wrote above and elsewhere, I'm not sure about your > interpretations yet. Let's bring all the discussion about this in this subthread though. Friendly, Sven Luther
