Actually eXist is a bit of a mish-mash of licences... Any parts of eXist I have authored will be under the BSD licence where = indicated, as I much prefer that over GPL or LGPL. But eXist also in places has borrowed code from other projects and these = have their licences indicated as appropriate, I saw one today that was = under the Apache licence - FastByteBuffer.java for example. Also there are plenty of third party jar's that eXist makes use of that = are released under various different licences. So its a bit of a mixed bag...

In theory, you'd have to distribute that change under LGPL. http://www.gnu.org/copyleft/lesser.html Of course, we'd like it if you contributed back to the project. > it have same specific support? I'm not sure I understand the question. It sounds like you just want to use eXist verbatim embedded in another software application. As such, LGPL will let you do that without any entanglements. --Alex Milowski -------------------------------------------------------------------------= Using Tomcat but need to do more?

> Actually eXist is a bit of a mish-mash of licences... For the database core or the query engine itself there should be no doubt that it is LGPL, even though it links with non-GPL libraries. > Any parts of eXist I have authored will be under the BSD licence where > indicated, as I much prefer that over GPL or LGPL. I won't object if extension modules (which are clearly marked as such) use a different license. Contributions to the core should remain LGPL though. Just to avoid any confusion. > But eXist also in places has borrowed code from other projects and these > have their licences indicated as appropriate, I saw one today that was under > the Apache licence - FastByteBuffer.java for example. There are some rare cases where I adopted single classes written by other people. I found it appropriate to include a reference to the original author and the license under which their code was published. However, 99% of the code were written by us and not copied from other sources, though I will always readily admit that e.g. saxon has been a major source of inspiration. Finally, my position concerning licenses has always been tolerant: though I like the GPL/LGPL I would probably have been willing to switch to a different license in the past. However, nobody really tried to convince me, so I'm happy with the LGPL ;-) Wolfgang |
