..._and_ you distribute binaries, _and_ you actually link to the MySQL codebase as opposed to merely using it, _and_ you haven't haven't negotiated a licence exception from the copyright owners. If you're going to characterise licence provisions, please take the time to be accurate. > Postgres has a BSD style license I believe, so there's no requirement > to release your sources if you incorporate it in your own apps. It has a two-clause BSD licence, which means you can create _and_ distribute proprietary forks, and the only things you're not allowed to do are sue the copyright holders or assert warranty rights. > License-wise, Firebird uses a Mozilla style license which > as I understand it means that you only have to release > source on those parts you modify which have to do directly > with Firebird. Again, you are in error on the "release sources" concept. Copyleft licences such as GPL and MPL trigger obligation of source code access only if you distribute binaries. (In the case of MPL, licence provisions apply separately to individual code modules.) The point, particularly in relation to databases, is that many deployments involve remote usage of the code, without distribution of it. Hence, no obligation of source access, even under copyleft licences. -- Cheers, Paranoia is the delusion that your enemies are organised. Rick Moen [EMAIL PROTECTED] _ Philippine Linux Users Group.
